How to pull a boat engine

[grahamh]

Ok this is not as stupid as it sounds.

I know how to disconnect the engine, drive, etc.

I'm more curious about what device you guys use to actually lift the engine out. I've pulled lots of car engines in my life, but I don't think that a normal automotive engine crane would be tall enough. Is there some sort of marine engine crane? I tried searching but had no luck.

My boat's engine is actually running great, I'm just curious should I try this in the future.

Thanks.

A good size tree, large tripod, backhoe, helicopter, A nice beam coming out of the peak of the garage is what i use. Depending on boat size sometimes you can gat the automotive crane in the boat to atleast get the engine cribbed up on the floor of the boat.

A few years back I pulled an engine from a boat and undid everything at home and towed the boat to work and used the forklift to lift it out and then put the engine on a trailer, then towed the boat back home.

Google chainfalls and gantrys

I'm looking at replacing the blowed up 5.0 in the SeaRay.
I'm thinking it will take a pulley setup on the big tree out back.
None of the auto cranes I have access to can get high enough
to pluck the motor.

Ayuh,... Not saying it's Your answer,...
But,..
A couple years ago, a guy posted pictures of using a automotive engine hoist, chained into the back of a pickup to get the height needed...

I can see that. I have to see how far the hoist can extend and still be stable.
I think a pulley setup under the big tree may work best for me though.

Re: How to pull a boat engine

just look for a tow truck and ask him how much he charge you to lift the engine out... they charged me 70$ when I did mine.

Cool thanks for all the advice.

Re: How to pull a boat engine

I used my car engine hoist I made a tube that bolts in the end and extends the beam 3 more feet and then bolted the chain to the end of the tube to pull the motor I made it a couple years ago so I could pull motors from cars while they were still on my trailer to go crush the cars. You just have to make sure you have a extra person to stand on the back of the hoist so it won't flip with all that weight out so far. I had to use my 225 pound neighbor to stand on the back. MAKE SURE THEY DON'T GET OF. With the tube in the end of mine it will go 11' 6" at the highest point when it is all the way up.

I was thinking something like this might work, I could probably extend the legs too to help deal with the instability.

That's very helpful. I think I may actually be able to pull this off (or out as the case may be)

Re: How to pull a boat engine

I was able to use a standard auto engine hoist on mine.

I let the air out of the tires to get the boat as low as possible and also raised the front of the trailer as much as possible to get the transom as low as possible.

I cleared the boat by only about 3 inches.

Re: How to pull a boat engine

I am thinking of doing this also. I am a crane inspector. Some things to think about. As you lower your engine to working height it will change the dynamics of the hoist/crane. I am going to use plate steel and/or sand bags as a counter weight. They won't step off to get a beer.

Same here. I may have actually removed the tires and set the trailer on jackstands or blocks of wood (foggy memory). Cleared it by a few inches.
