Q:
I changed my engine and the coupler doesn't fit the new flywheel. The bolt pattern on the coupler is smaller than the bolt pattern on the flywheel. What coupler would I need to replace my 984290 coupler to fit the new flywheel pattern? The engine is a 1971 or 1979 Chevy 350 small block.?
A:
This would probably require the help of a technician. Reason being is there is no way for us to match up a new flywheel with a coupler. We can only cross reference OEM numbers. You can post a question like this to our forums at http://forums.iboats.com or contact a local technician.
Q:
Is this replacement part for a 1987 5.7 with cobra out drive?
A:
Yes, this should work just fine with that application, among a few other Volvo Penta or OMC/Cobra applications.
