Engine removal

[Txlawdog]

Greetings all. I am about to pull the engine on my 1985 Catalina 30 for a complete overall. My question is, how to you separate the shaft coupling from the transmission? I removed the four bolts and I noticed 2 set screws on the shaft. Do I need to remove these also? I have read several threads on this topic but I am still unclear on how to separate the two. Does the prop shaft slide back to allow for engine removal? Any thoughts would be grateful. Attached is a photo of what I am looking at. The boat is in the water and the last thing I need is water coming in if I screwing something up.

The set screws hold the shaft half of the coupling to the shaft.

Since the four bolts are removed the coupling halves should separate when the engine is moved.

Thank you River for the info. I am going to work on it this evening.

When I separated that coupler it did not come off easily or immediately. There may be some corrosion holding the parts together. ALSO....doing the work while the boat is in the water will likely start some leaking at the packing as the pieces are disturbed. Great care will be needed and you might want to support the inboard end of the shaft when the engine is moved and removed. I would hesitate to do the job in the water.

C'mon, people don't have to haul their boats to pull an egnine.

Why go further than separating the couplings? If the engine goes up (only) it should clear and if it goes up & forward it certainly will.

There was a thread here about a week or two ago about a C30 skipper who added lotsa access around his engine, forgot if he pulled it or not.

Good point about supporting the shaft, very good.

To insure the engine goes straight up or forward I will remove the engine mounts at the base. Then slide the engine forward about an inch. I got the coupling to spin independent of the transmission so all seems ready for the lift.
