O.k. putting the motor in the gullwing. Seem to have issues with the jetaway. The u-joint yoke is stuck on the splines. I'm guessing since there is zero play on the splined shaft that this is where I'll have to get my clearances, but it doesn't slide and won't even come off. When I got the jetaway the yoke was already affixed to the shaft and I figured that's just the way it's supposed to be. Now I'm guessing not. If I try to use it the way it is now, I'll surely be putting undue pressure on the crankshaft and I know that's not good. Once again there is zero play forward and backward on the shaft itself.

I attempted to get the yoke off the splines by gently prying on it with a crow bar and it won't budge. It's like it's a press fit and I'm pretty sure it should just slide on.

Help! Anybody that knows these things. I could sure use some info (in particular how to get this damned yoke off the splines). I tried to call Duane Oblander, but there's no answer at the shop. It is probably lunch time though so I'll try back later.

I'm afraid if I put too much pressure to it, I could screw up something in the jetaway. The only thing I could think of would be to put some heat to it, and possible some penetrating oil. The yoke was badly rusted when I got the deal and that might be contributing.

Here's a couple pictures of it.

Dan, put a good penitrating oil and let it sit awhile. I had that problem with the cruiser and it took some doing to get it off. I used 2 long prybars and alot of muscle with a few quick raps with a hammer to shock the rust and then it came right off.

Wouldn't have a problem if you had a v-drive:D

I would use a puller, or a press, maybe a little heat to the yoke. It does not take much of a burr to lock those on, although it does take some force to get them on when it has a burr.
If the yoke is blind then it may only have a thin sheet metal disk tack welded in the end. Drill it out to get the puller in.

Thanks guys. You were all right on with your suggestions. While I waited a while to call Duane back I used some penetrating oil on it and whacked it a couple times, then tried the pry bar again. None of that worked. I called Duane back and spoke to him. He suggested the puller deal and I didn't have one big enough to fit. I figured I'd drill my hole in the plate/cover before going to buy the bigger puller. When I pushed on the drill it moved a bit. I went back and forth in and out a bunch of times (actually that was before I started working on the boat) and finally got it.

She's all greased up and good to go now. Also got some more spline in there as you suggested Tim.

My driveline alignment still isn't perfect, but I'm going to call it good to go.

Don't laugh at my home made battery box. I'm too friggin cheap to pay $150 for a box (no matter how cool they look).



Thanks to everyone.

Crisis averted.

looks real clean Dan. when's the first river trip?
It does look real clean. They always look good when you can get in there and clean it without a motor. Unfortunately, it only takes a few minutes of slinging fresh grease off the ujoints to screw it all up. ;)

May 25th is the plan. I've still got a bunch of things to do though. This little snafu today kept me from doing lots of other things. Aint that just the way it goes though.

Amen that. My Kachina even looked pretty good once upon a time.

Shit I ain't laughin'. Look at mine. And it's not homemade. I'd probably be better off if I did make one. It's big and clunky and takes up a lot of room, that I need for other shit.

Looks good Dan!:)devil Nice and clean.

Please ignore the clusterfuck of wires in the way, still working on that.

Just keep hammering away HJ. Get the mechanical/electrical stuff straightened out
and then you can mess with the other. As I'm sure you're finding out.......it's never
ending..

This is pretty funny. I was going through some old photos of the Kachina. When I
first got the boat this is what the u-joints looked like. It had probably been run that
way for years.
