really?? because it works just fine! incase you didnt know the whole drive system is modded and shaft rides on ceramic bearing. there is a gap but aint much but its there.

Well, I will be rude that is a recipe for disaster on the photos posted, that I viewed and posted on...especially at the motor connection, as previously stated. Shaft or flex drive a huge difference? The pictures look like flex. If it is a shaft it is OK but not the best drive system. That pond is also a recipe for disaster...WEEDS and way too short

Laddie, you have some real problems with the drivetrain, your bare flex drive connection at the motor is way too long prior to the stuffing tube and you left no clearance between the drivedog and the strut. My 2 cents.

Douggie

Douggie- the coupler is a square-slip, making the drive a two piece setup. There's a step up on the hard prop shaft in the strut, the prop dog should be snug up to the strut, no gap, on this setup. If there is a gap, the shaft will fill with water and leak inside the hull.

When the cable contracts in this setup, it simply moves in and out of the coupler. This is quite an unusual setup from the factory.

Here, these should explain;

In the first photo, notice the step up in the hard prop shaft. It's slight, but keeps the shaft captive in the strut as shown in the last photo.

There is only 1 set screw in the coupler, on the motor side.

That is a weird setup but thanks for showing the design. I just stumbled onto this thread and saw your photos and went what the hell is that and did not read the whole thread.

Thanks,

No worries. It is indeed an odd setup. All of the "joys way"scheiße boots use this configuration.


BTW- the extra fiberglass around the motor mount prevents the hull from cracking and is holding up well. It just need a little stiffness.

Anyone have the Super version yet ? I wonder if the motor mount is more secure on the super version to prevent the hull cracking ?

So you pulled 130 amps on that motor?
if it is good i might go with 2 of the 1100kv version of the same motor in a mean machine.
