I have reworked my transom in my 1972 SS215 Slickcraft 21.5' to take a Mercruiser instead of the OMC stringer it once had. I Have the transom assy. plate,gimble, and 1.50:1 drive from a V8. I was going to put a 305 or a 350 in it, BUT! I found a boat today i can buy reasonable with a good 4.3 eng. and Cobra drive. (1) Can i use the OMC manifolds to hook up to my Merc exhaust Y tube? or do i need Mec manifolds?(2) The 4.3 is a Gm It is a 1.50:1 eng correct? (3) Since i already did my transom over I probably wouldn't use the whole Cobra set up, Opinions?
