Engine R&R Hours

Have to have the yard put a "new" rebuilt Yanmar 3GM20 in for the one that just self destructed. It's a 34 footer with restricted engine access, especially to the rear. Anybody have a feel for how many hours it'll take to remove the old one and replace it with the new one? As always, thanks in advance.

Re: Engine R&R Hours

If you didn't get an estimate...prepare to be at the boat the whole time they do the job and log the hours.

Taking an engine out can be a long days work depending on wht needs to be disassembled.

If there is anything you can take out....do it

Re: Engine R&R Hours

Should take two guys a day to pull it and a day to replace it, but get a fixed price if you can. I could sing you songs of woe all night long about what happens in boatyards. Basically they get prisoners on work release for $2/hr from the state and charge you $100/hr while they learn how to use a screwdriver.

Re: Engine R&R Hours

A friend of ours has just taken out and replaced same/same unit all within one day's work. It is all dependent on how tight the installation is and how difficult it is to move the engine to a place where it can be lifted off.

Plenty of pre-planning will save plenty of wasted time.
