I was wondering if anyone has pulled the engine themselves on their boat? Besides my oil leak there are so many additional issues that could be more easily addressed with the engine removed. Wondering if anyone has undertaken this project themselves. Most of the issues seem doable with engine out on a floor stand. I like the boat and have customized it to my uses so cleaning up some maintenance issues and design issues seem attractive if engine removal not a deal breaker. I have access to a forklift so that part is not a problem.

For instance things that could be fixed/replaced-
The engine mounted electronics and fuel pump (should be mounted on hull), as they are shaking themselves into early failure mounted to the engine, the engine mounts that probably need attention, replacement of alternator, idler pulley and belts, reduction of length of so many system hoses that are yards longer than they need to be, cleaning raw water cooling system and enlarging diameter of hoses to cool the system, wiring, bilge pumps, cleaning fuel tank etc. and just cleaning up other issues to feel more confident about the reliability of the boat. So many of these issues seem daunting mostly due to access.

Has anyone done this?

Thanks

Is there a how to video?
 
If you have a fork truck with a boom attachment you could easily have that engine out in 3 hours taking your time? Unplug the wire harness, remove the two fuel lines, pull the 12 Lag bolts holding the engine down to the bed, Remove the water hoses engine cooling raw water ,packing cooling hose, close the valves on the water heater and bus heater remove those hoses and cap the hoses going to the block, Disconnect the battery terminals. There should be lifting eyes bolted to the engine to attach a bridle. Lift it up and out and block it in your shop for repair. I have pulled engines out of a lot tighter engine compartments. It will be easier to service a lot of parts on the floor. I believe I could pull the engine in my Cutwater and replace the starter faster than I could replace the starter leaving it in the engine in the boat. A lot less swear words too!

While you have the engine out this would be a perfect time to do the cutlass and packing. Go for it!!
 
Thanks Brian. There are so many little problems that are annoying as hell to get to I think I will take your advice unless the oil leak turns out to be an easy fix, (unlikely, no obvious point of origin so far). It would be nice to have the engine compartment well laid out, cleaned, no more oil leaks with all the excess wiring gone.
Probably a lot of extra space once this is taken care of. Good to check if those lag bolts to engine mounts are really doing anything as well. The engine has always had a little vibration.

Thanks again,
