Re: Pulling the Engine

I doubt you will be able to easily move a 4-236 engine easily even without the head and other assemblies. I wouldn't try and do such a stunt again and have the back operation to prove it. It's no big deal to pull the head and easily removed ancillary parts if you do go the disassemble and remove route, however.

Cutting the sole of the cockpit is a much more cost and labor efficient way to go. Wouldn't bother with a hatch as you'll probaly never need to pull the engine again. Just cut and reglass.

Re: Pulling the Engine

I'm nearly finished building a centre cockpit boat where I've made the choice to "build in" the engine (Yanmar 75hp). It's only a 2 litre engine with a turbo so once I remove the external components the block should be manageble. However, like all things it's a compromise. "Building it in" means that I could put extra shelving and galley bench space above the engine, something that will be used daily, hopefully for 20 years before I need to pull the motor.

Just make sure you continue to measure once, twice, three times and make sure the hatch idea will work.

As an errant electron - you could go the disassemble route to get it out - it's gotta come out anyway, right? See how difficult that is and then do the hatch mod if required while the engine is getting done.
This is something to consider. If it's hard to work on the motor, a hatch maybe the way to go for EZ access in the future. But if it were mine I would definitely go thru the cockpit for the install.

I've rigged a lot of machinery in/out of boats and it seems if you don't have the gear, stuff gets damaged or broken, even oneself.

Re: Pulling the Engine

Thanks for all the feedback. I am going to cut the cockpit and will decide about the hatch while the engine is at the dealer.

Re: Pulling the Engine

I'd go with building in a new hatch for access. I had the same problem with pulling the engine out of Sabre Dance, and after looking at Tate n Dani's blog, where they changed the engine in their Westsail 32, which has the cockpit sole hatch, I hired a contractor to cut one into SDs cockpit and frame it with angle (she's steel).

Pulling my fuel tank took 15 minutes, most of which was the rigging for the lift. Pulling the engine took 20, only because the fork lift couldn't lift the engine high enough to clear the cockpit coaming and I had to rerig the lift.

Re: Pulling the Engine

I would cut thee hole. and have a good ships carpenter turn the deck into a removable access hatch.

Re: Pulling the Engine

I like the idea of a hatch because you can take the hatch off while working on the engine and get good light and air. Makes maintenance more pleasant.

Re: Pulling the Engine

I had this issue on my Ingrid 38. I cut out the cockpit floor, pulled the MDII and replaced it with a Yanmar 4JH. Then EPOXY/glassed it back in. The boat I have now has liftable hatches and I can see it's going to be a constant fight to keep it water tight.

Re: Pulling the Engine

I'd bite the bullet and do the hatch, as big as possible.
