Still working.
I went as far s I can on the boat port for a wail.
I did not go calling and the lawn did not need to be messed with.
Water bug time.
My buddy and I welded up some of the motor platform but did no get it welded to the boat.
I added some Pillars to disperse the weight , not welded in yet. I used a hole saw and cut the Sq tubing and drove it in , should hold better then just welded to the out side.



A VW motor mounts only to the transaxle so no actual motor mounts. I mane one . the motor will set on it and I'll bolt it on with the 2 studs on the front of the motor under the front pulley.





Then I plan on having a heave "L" bracket from the trany bell housing mount holes to the front of the motor mount.




The oil sump is in the very bottom of the case I had to cut a hole to change the oil.



Now I need more welding...

The VW motor is officially attached to the Hull !!!!
I have been fabricating a motor bracket and starter mount .
WOW lots of cutting and fitting But it looks just like I envisioned and
seams to work .
I have to be able to adjust the " attitude" of the motor 'drive.
I still have to make the "Adjuster" on the front.
It will consist of a one inch ,by three inch bolt and nut on a rubber pad
To move up and down and then a locking plate to hold it in place .
That's next.
THEN finally I can start the drive/hub/prop.

At long last I have the primary clutch "ON" the motor.
I had to relocate the starter an 1/8 inch as to let the front half turn freely.
 Every thing is turning to the left and all the screw on parts are right hand thread. I have roll pins and nut locks an anything in the "Drive train". I'm going to do a power up soon to see if the VW 1600cc will make the clutch engage.

Boy, if a tiny 2 cycle snowmobile engine (what CC size was on the sled motor clutch came off of?) will make the clutch function that VW motor surely should too. I forgot is it direct drive to prop or do you have a gear box between?????

The clutch runs off RPM.
 A new SB has to run up to over 4000 rpm before it starts to lock up.
No gears but the drive starts out at 3 to 1 and as the rpm goes up the reduction goes down finally to .70 to 1. It'll have a chain at 1 to 1 from the secondary to the prop.

Looking good D. 

Back in my Mechanic days, I worked for a fracing company. They had Nitrogen trucks with a drop box PTO. The output on the drop box turned clockwise looking at it from the back. We had a heck of a time keeping the output shaft nut tight. I would put a little BLUE locktite on the lock nut as well. (I never liked using red locktite)

We ended up having a nut machined that was split and had an allen screw that would "clamp" the nut to the shaft after it was tight. That worked, but was a real pain to tighten the allen screw. 

It looks like you will be on the water pretty soon. Way to go D.

Major test . A+
1971 VW bug 1600cc undetermined  mileage motor.
This set in a shed for maybe 30 years. I Got a new carb at amazon,
New coil, plugs wires points and condenser. I set the valves and point with a feeler gauge ,remember them ? I had it running on the ground for like 5 minutes for the first test of the clutch adaptor that I had made. It failed in moments. I redesigned and had it fabbed up again, This time with a carrier bearing and a shaft that went in to the piolet bearing in the crank. Have not ran since. I built the hull made the motor mounts and finally mounted it on the boat.
Made a mount for the carrier bearing re did the starter to fit.
About a year later. Today I needed to start it up and see if my primary clutch off the 1969 Johnson snowmobile would even work.
Dang! I put the fuel line in to a gas can and hit the starter. A dozen turns and she came to life. I have not put a timing light on it yet but it ran very smooth from, 800 rpm (Idle) after the electric choke came all the way off , to 5000 rpm ( as fast as I wanted to turn it unloaded). As stated in the information I could find on the clutch It engaged at 1700rpm and at 3100 rpm was fully moved in for the reduction change. Everything sounded smooth and solid. I ran it for a half hour or so at 2500 rpm. I still have to do some work on my temp and oil psi apparently, but the oil on the dip stick was still cool to the touch.  NICE!
Next to mount the secondary clutch, and see if that part works as expected !!!

Houston there Could be a problem...
I just read that the type of clutch (Salisbury Clutch) off the old Johnson's where only rated to 40 hp.
The 1600cc vw is rated at 60 hp.
I'm thinking with the high altitude and loads of miles on the motor I'll probably be closer to 50 hp.
Hope it will work...

It is a centrifugal clutch,  Many of those don't disengage when speed is reduced...IF there is a heavy weight (mass inertia) load on them...they stay locked up.  You prop may make it lock in 'engaged' mode!  
Keep you finger on the 'kill switch' as you try to go to neutral.   A short stop is much better than an unwanted travel up into a dock/parking lot.


Clutches are not usually rated/limited on a horsepower basis.  they are rated/limited on a torque basis.

If the snowmachine ran at a higher RPM for that 40 hp rating; then if the VW engine is running at a lower RPM than snowmachine engine....you will be limited to torques much lower than the torque available from that VW engine, even at  an aged 40 hp.

Also decelerating with the high inertia prop might get torques higher than the rated clutch torque, thereby skidding the clutch friction material.  (wearing it out quick).

Just thoughts from an old engineer!

Yo d4570...no mechanical ability or knowledge here but..wondering if there is a direct relationship to rpm's to clutch vs hp creating those rpm's????.....for example could you control the power output to the clutch via rpm's?...so as to not over max the clutch?

Like...Find out what were the max rpm's on the old Johnson motors of 40hp that were required to allow the clutch to "open" to put full output to the belt (allow it to drop down to  bottom of "v" for full power) and what they said was the max rpm's to the clutch to achieve that result.Question

Thanks.
There is nothing to slip in the clutch.
 it consists of a spring rapped around a shaft.
The spring pushes the sides of the pulley outward making the
belt ride higher on the sides  changing the gearing to the secondary.
Which opens wider from the "Shorter" belt and spring presser and that changes the rpm to the prop. There all on splined shafts they can't slip, the belt can but not the clutches. When its in "Neutral" it is just the belt two "LONG" to engage the sides of the pulleys .
So there Not actually a centrifugal force friction clutch.
There a variable "Step" belt drive like on a drill press only automatic, kinda. 
 
Look at the bottom part of the exploded view and see the clutch assembly

The VW gets its max HP at around 3000 rpm I could just limit the speed of the motor, BUT I NEED all the HP to spin the prop I have.

The primary sheave is centrifugally operated and engages the trans-mission belt when the engine speed reaches approximately 2700 rpm.When the engine is rotating at idle speed or below 2700 rpm, the trans-mission belt rides on a ball bearing between the halves of the primarysheave assembly (see Fig

As the engine speed increases, centrifugal effect forces a garterspring in the end cap outward against the contour of the end cap and axially against the movable sheave half. The profile of the end cap causes the engagement.  As the sheaves are broughttogether the transmission belt is forced outward to ride on a larger diameter of the primary sheave assembly, increasing belt speed (seeFigure 3-8). Since the belt length remains constant, the secondarysheave halves spread apart, allowing the belt to ride on a smaller diameter (low gear).  As the belt climbs between the cone pulley assembly the gear ratio decreases (high gear).


If the torque rating is increase above the rated torque,  the movable sheave will rotate at a speed slower than the outer primary sheave (input speed).  this will causes the garterspring to move at this slip rate, and wear against the wear  disk and/or the  end cap.

The assembly also includes a wear disk.  Which I assume is to compensate for undesred wear, but is very limited.  The wear would be preferred to be on the softer wear plate than the garterspring or the end cap.

If you know the HP of the VW and its top rpm, along with the HP of the snowmachine and it's top speed the max torque of each is easily calculated.
D,  you always have the most interesting  and thought provoking issues.  BEAR

If this helps your thinking.

60 hp @ 3000 rpm means max torque output of VW engine is   105 Ft lbs.

The Snowmachine   40 hp engine, if it was made to run at say 5000 rpm (just a guess for a 2 stroke)  would have a shaft max output torque of  42 ft pounds.

These are MAX calculations.   Only a test will tell.

Where is the extra chain drive transmission you installed?  between the vw engine and the SM clutch?  between the SM clutch and the prop?

Remember the VW engine will only put out enough torque to match the prop load. 

 Propeller loads increase with the square of the speed.  So if you double the speed of the prop...you need 4 times the torque.


Posted By: d4570

The chain is after the clutches. To the prop. I can change it easily if needed
Right now it is 1 to 1.
The clutch starts at 3 to 1 and finishes at .70 to 1, a little over drive...
The prop is made to run at 3100 rpm and with max pitch takes 55 hp to turn it at that speed according to the prop people.
THATS the reason for the torque converter. 
Normally a 1600cc can't get it turning that fast because there max hp is at 3000 rpm, that is with out a reduction , but then you need to run your motor at 4000rpm + to get to the max on the prop..
 It's like chasing your tail.

The prop required torque to reach 3100 rpm would, if my slide rule is still working, be    93.5 foot pounds of torque.  
   
Sounds to me you are very close, on the torque ratings.  your CV, Continuous Variable transmission, is centrifugally controlled, sort of an automatic.  And I suspect the bell housing curve is profiled for the snowmachine thread load and a 2 stroke.  So you might not get to top speed the fastest, BUT it should take you there.

Still looking like a sound project D.

We are anxious for the test results on run up.

I did a no load, no prop today.
All looked good. The clutch started to move at around 1800rpm.
I did not have my laser tack on the hub but it looked slower then the drive.
It starts out at 3x1.
As I increased the motor RPM the clutches both moved, as expected, the clutches
Topped out at 3000 RPM, right where I was hoping.
I should be like .70x1 there ,I would guess around the top end for the prop, 3100RPM.
I didn't run it long but It was quiet and smooth and looked to be running true.Clap

Well.
I did some more welding to make the prop tower absolutely ridge.
I did a dry running of the prop and drive at full power.
Every thing looked true and I felt no vibrations or odd sounds.
I did not run it long The clutch kicked in at 1500 rpm and at 3200 it
Had moved to it's extreme extent.
It is supposed to start at a 3 to 1 reduction then at full it should be at
near 1 to 1.
I was having a problem hand working the gas ,watching the motor tack, and
the lazar tack on the prop. But it looked like at 3200 motor speed it was 3100
prop speed. I was using my wooden 64" 34 prop.
It spun up to speed as fast at I could move the throttle.

I'm hoping the 3 blade 54" will load the motor a lot more, Or I'll need more prop.

CryDid you have to rub it in? Like 80* there and sunny right ?
I can only run it at full rpm for a few seconds It blows everything in the shop around I'm afraid something will hook up with the prop and that would be a disaster.
I'll try and pull it out in to the alley and try the 3 blade.
Still no way to steer it yet.

Headers on the bug.
With the new little welder I'm plugging along.
I made some headers for the bug motor.
The easiest way was to use the existing pipes and ad
crisscross   Pipes. They point out to the side right now but will
point to the back, I have the mufflers from the "Johnson" jammed on now and they make the bug quite quiet. I'll work with them .
 
 
I did some digging and found out I have my distributor "Plumed" wrong.
When I got the carb I used the vacuum lines that where on the old one, used them by size and they seamed to work.
But on a VW they put vacuum on both sides of the advance diagram
and I had them backwards. AND come to find out In my application , I need to uncap one and leave it to atmosphere and plug it at the carb. Then , this is odd, I have to find TDC of #1 mark the pulley where you time it from mark the Degrees to 28*.
Run the motor up to 3500 rpm and set the mark to 28* Above TDC. I also found out an old fashioned distributor with mechanical weights would be the best in my application. 
I'll have to look in to that if I cant get it to 28*.

What you need is dual point distributor, you leave it retarded enough to start easier, then as you come up in rpm, you hit switch for second set of points and it advances your 28 degrees, to get the high rpm and pump some fuel on through.

That used to be the hot set up, before computer tunes and even before going to twin magnetos. That along with the heavy weights and light springs, controlled how much power, you put to the ground or prop.

Ok ! 
I re plumbed the distributor as directed, and left off and plugged the second Vacuum line.
I used a  * print out , worked great.
I found TDS on #1 marked it and took off the prop.
I fired it up with the timing light on it.
Ran it up to 3500 rpm and twisted the distributor till I hit
the stud that was used to hold the old manual fuel pump( I have it capped off ) and use an electric fuel pump.Not quite to the 28* mark with the vacuum line off as needed .
I was able to cut the stub off some to let the distb. turn farther.
I set it to 28* clamped it down, and put the vac line back on.
Put the prop back on and...
PERFICT!!! I now have enough HP to turn the prop up to the required 3100rpm.
That's all ,but it is right on 3900 rpm on the motor and holds . Nice.

Bear, I was trying to get it stopped before we hit the 4wheeler.
 The accelerator is a string and it's up front I had to be able to pull it .

Started the cage for the prop and drive.
 
 
 
 
 
 
 I'll have three "Hoops" I want to cover the drive unit too as well as the prop.
I'll have a removable screen over the motor also .
I gave 2 1/2 inches for movement and in the event I go with a bigger prop If I hop the bug up.
That gives me 3" to spare to get out of the shop I may not be able to get it under the boat port on a trailer, Dang it.

Ailerons

Un like most small airboats I plan on running "Dry" and on Ice a lot.
I need to be able to adjust the attitude of the boat differently then on water. 
Here is my plan.  "Ailerons".
I'm going to put 3 small ones before the rudders, to lift the front or back depending what I need.
Remember "work in progress "

Remember, if you don't need all three, you can easily take them off.  but putting them on later would be a pain.

I have the structure in for my "Elevators " I found out that's what there called not Ailerons. Anyway , and rudders .
I still need to attach the plates and cut them to fit.
There will be 3 elevators 36" X6" and 2 rudders 50"X 10"
 Going to use ss steel hinges to attach them and use  a "Drag link" to hook them together, and move them up and down with a car window motor.
The rudders will be the same but turned with a Mechanical shafts and bell cranks.

Really looking good now. A lot of effort for a project of that complexity. Did you guys actually make any kind of design drawings ie engineering type like blueprints to scale? Before you started cutting and fitting things together. Anyone predetermine what stresses will be put out by the engine and prop against what is holding the parts together? So you will know that it won't "fly apart" under full power and loaded with gear & you guys. You will certainly have to "host" a showing when we all show up for MYGAWDS.

There looks like a "belt" hanging from the generator or alternator in one picture.

Plans ? NO
Drawings ?NO
Engineering ? NO
But if it is worth building it's worth OVER building.
Just a complex Image in our heads.
Yes there is a belt, It is the replacement Generator belt, I just have not got it on yet.

I always have 4-5 extra when I rebuild an automatic transmission!!!  Got a bushel baskets of extra parts from rebuilds!Geek

No engineering? No problem. 

If anything is overstressed you will find out pretty quick. I have built a lot of things that I had to modify a little bit after I started using it.

In my early days as an engineer, we designed to 3 significant figures (the limit of our slide rules.  Then doubled it.  when I retired in 2008, the rule was design to the minimum, then add 5%.

Life moves on.

In 1967, no ne shipped anything that wasn'r fully functional tested. Companies had what was called the TesRoom (shed/building).  Today, they ship it before the design is done.

Think of electric trim tabs on your boat should not need to changes fast. What I intend to do with them is, trim of course in the water but also to make the front " Lighter" if I have to go up over something like getting up on to the ice on a partly frozen river. then shift down to drive the air to the surface to help "Lift" the back and get some "Ground" effect for a little more push.

Slow is no problem.  I think you will use it for 'take-off' mostly, to get you out of the 'hole'.  Raising the rear elevator will push the rear down, thereby raising the nose.  To be effective the elevator will need to raise up 35-0 degrees on take off.  it should be neutralized (zero angle) at running.  But if some permanent 'trim' is needed, it can be set as the zero movement point  with the threaded rod arrangement.

looking good...moving forward.

I needed some U joints for the steering on the waterbug.
There like $30 each on the computer, I need three.
They turn slow and only one revolution so I did not need precision just flex to change sides of the boat with My tubing. They fit over the 1" tubing I'm using.
Handle bars will turn a drum with cables to the tubing shaft.
The shaft will run the length of the boat to the back.
Then a drum back there too with cables to the steering arms on the rudders .
Closer by the day...
