Default repower 1999 4600 SCB

Hi

I need a new engine on my starboard side. I have cummins 370 in there now

I have called and gotten a price on a long block, but would like to know if anyone has ever done a repower on this boat and how did you do the engines?

Assumign through the main hatch?

Tom

stripped down, through the main hatch. Lots of cribbing and an gantry style crane will get built inside to lower it into place. This is not a DIY project if you've never done it before.

Take the time to clean and paint the bilge while the engine is out. Also consider when the last time the stuffing box or dripless was serviced and take care of that while it's wide open. Also consider when the shaft bearings were done. Since you're already uncoupling the shaft, consider replacing cutlass bearing.

Technically, with twins I would do the stuffing box/dripless and cutlass bearings on both sides at the same time.
