This engine will bolt in, and work in nearly all 305 5.0L & 350 5.7L marine applications from 1987-2013 with virtually no modifications. This engine will also replace many Pre 1986 engines, which have a two piece rear main seal, but will need to update the engine coupler. If you have a Pre 1986 engine please give us a call for your specific application needs. Inboard engines with a top mounted starter should re-use their old flywheel. A new ring gear will make your old flywheel as good as new.
