Well Not sure on the rebuild package for the 250. I though it being I/O it would possibly be Fresh water cooled (FWC). I could be wrong here, but raw sea water stright to any marinized motor usally means rather short life span. Good luck, if it was OMC or Mercruiser I have links for that stuff seeing I ahve been working on this prodject.






I bought it not running last Sept. Started really working on it in June, got it running, found that the inner and outter exhaust housing cover gaskets were bad. Went to replace them and busted bolts.

Now I have this mess to deal with, Mmmmm Busted 1/4-20 bolts rusted and stuck in an aluminum alloy power head.




Soaked for a week with Kroil, and WD-40, Vise Griped (Didn't work), Drilled out the center and tried easy outs (Not so easy, didn't work) Let soak for two weeks with my my WD_40/Kroil blend. No good. Going to have machinist freind deal with this issue as I am leary about using a torch to try and free them up on a 36 year old motor that I know works.
