I have an 88 omc King cobra set up 350. I am putting an older style 350 in it and it has a larger crank bolt pattern. The engine coupler will not bolt up. It has a smaller bolt pattern than the crank I have now... Help ASAP!?
Well we only have the ability to match up parts to specific engines. We do not have tech services to recommend conversions like that. You will need to contact your local OMC dealer for specific guidance.
Is this replacement part for a 1987 5.7 with cobra out drive?
Yes, this should work just fine with that application, among a few other Volvo Penta or OMC/Cobra applications.
