Prop shaft coupler removal
I have only about 3.5 inches of room for a puller here once I add a backer plate to the coupler for the puller. Not to mention the starboard engine has more stuff in the way to even get in there. What do you guys suggest? This is a 1970 38 ft Connie.

Re: Prop shaft coupler removal
Place a spacer between the end of the prop shaft and the end of the transmission output shaft. Re-couple to the transmission and carefully and evenly retighten the coupler bolts and push the shaft out .

Re: Prop shaft coupler removal
Agree with Greg. Or blast it with PB and tap tap from side to side and see if it starts to move. I use a brass drift and a hammer so
I don't bang up the flange. It's tight, but not pressed on. Good Luck!

Re: Prop shaft coupler removal
both good suggestions....combine the PB with the press out tactic....will work...be patient....and, as said, don't use a steel hammer.....
Some guys have experiments with freezing to shrink and heating to expand various parts....but access precludes that in your case I would guess.
Good luck....use LOTS of PB Blaster...over multiple days.....

Slide hammer for removing the shaft from the couplers.

I like the slide hammer idea although I hear some "don't do it", have you had good luck with this technique?

Re: Prop shaft coupler removal
I have used the slide hammer method numerous times over the years.
it works great! only caution is to stop as soon as the shaft clears the coupling so you dont jam the shaft key into the packing nut.
best to have a helper watching the coupling while you run the slide hammer.
takes about 10 min.

Re: Prop shaft coupler removal
I have had excellent luck with this over the last 20 years. I can't even begin to count how many times I have used it on everything from runabouts to cruisers.Jim Godlewski wrote:Jim,jim g wrote:Slide hammer for removing the shaft from the couplers.

A coupler is suppose to be fitted to the shaft by the company that made the shaft. They should also check and make sure the face of the coupler is 90 degrees to the shaft when fitted. It should be a press fit. Which would just require a moderate amount of hammering. If you have to use it as hard as you can to put a shaft in then the coupler hole is to small.
