How are you determining its bent? Just visually?

Have you hit something or had anything happen that would cause it to possibly bend?

If not, you can check for a bent shaft by loosening the bolts at your dampener plate and using a feeler gauge while checking it every 90 degrees. There should be no more than .003" gap on any one side between your plates.

Here's a great video that goes over how to determine if your shaft is bent, then what to do about it: http://www.youtube.com/watch?feature=player_embedded&v=3zZ2mSH_Ncc

The guys at Discount Inboard Marine are excellent for helping you figure this out also. http://www.skidim.com (http://www.skidim.com[/URL])

Looks bent and twisted. I went through that with my 92 and ended up replacing all the gear.

I had the same issue on mine and fixed it all myself. Bent and tweaked it back to true and new cutlass bearings she was good as new.

How difficult is it to removed and replace those cutlass bearings?

Any tips on replacing those bearings?

LOOK at This bend from a log.

How did you get it off the bottom of the boat? Heat gun? I just bought one yesterday but it's been so danged hot I haven't had the motivation to pull it.

After u remove the 8 bolts i used a box blade an as u turn the strut left & right cut the seal off it will fall off from the hull.

07-02-2012, 01:22 PM
Man, I can't move mine AT ALL. I can't turn it and I don't think I can get a blade under it. I'm gonna hit it with a heat gun tonight.

i just went thru this..the new strut came with bearings so you are all set there. new packing of course and while i had the shaft out i replaced the shaft log hose. mine had gotten soft over the years so with a new one at a whopping 6 bucks went ahead and replaced it...while you have it all apart it would for sure do it.

Thanks, I order strut, packing, shaft log hose from DIM today be here on 7-5-12, what is the best way to remove the coupling on the tranny end of shaft.

07-03-2012, 04:28 PM
on mine (88 prostar 190) i removed the coupler from the transmission then removed the cotter pin and castle nut from the shaft (mine is keyed). then place a socket in between the shaft and the transmission and tighten the shaft coupler to the transmission coupler. the socket as you tighten the two couplers together will push the shaft out of the shaft coupler. I soaked mine liberally in penetrating oil. pretty straight forward deal.

07-03-2012, 09:56 PM
what size is the nut that is on the end of shaft were the coupler is. My shaft is 1" so i"ve tried 1" 1/8 1"1/4 1"3/16 30mm 27mm i"m lost. HELP PLEASE THANKS

07-05-2012, 02:27 PM
i have a power slot so i could not get a socket on it because of the distance between the transmission and the shaft log will not allow much of anything between the couplers..i used a punch on the castle nut and it spun off without a problem...it a fairly big nut

07-05-2012, 03:45 PM
Chrisoswald, Thanks i got it off w/ a 1 1/4 thinwall deep socket i have a 1:1 so i have room to move the shaft back through the shaft log.

07-08-2012, 12:28 PM
AS i start to up this back together i have a ?, shaft as it comes out bottom of hull is not in the center, it is at the shaft log by the stuffing box bolt. With the strut not bolted down i can move it to center the shaft on exit. Do i need to drill some of the holes bigger or what? Thanks

07-08-2012, 04:52 PM
Do you have the strut sealed down yet? If not, try putting down the sealant, threading the bolts, then holding the shaft reasonably centered (as long as it's not actually hitting the shaft log, you'll be fine), and tightening the bolts. If the strut is straight, this should be all you need.


07-08-2012, 06:06 PM
i replaced my strut centered it in hole through hull .and then moved the engine a bit to get the shaft to line up .you want the shaft to come through the center of the hole through the hull

and then align engine to shaft.


07-08-2012, 06:09 PM
Thanks Frank, Yes the strut is new one. DOING a dry run before i put the sealant on an the shaft is not hitting the shaft on the bottom of the hull but it is close on the right about 1/4 on the left it is about 1/2".

07-09-2012, 01:25 AM
I'd call it good.

Move the engine to align it with the shaft, then do the .003" gap alignment specified in the manual, and go skiing. The attached document describes the whole thing.


07-12-2012, 10:28 PM
THANKS FRANK, Got the shaft today, my 16yr old son a i moved the strut around alittle to get it right that put the sealant on an got all bolts tight. Shaft to motor is .003 all the way around. this is good right?

07-12-2012, 11:21 PM
Sounds perfect - as long as there isn't greater than a .003 DIFFERENCE between readings, you're good. You have .000.

Now get out and go skiing.
