Question
OMC exhaust manifold

I have a 909466 exhaust manifold for a 1977 Apollo boat with a 120hp 153 chevy motor and was wondering if you have a replacement? It’s possible that the last number is a 8 but it appears to be a 6.
Thanks in advance for your responce

Answer

Go2marine has the Replacement OMC Exhaust Manifold for your application.


Question
Replacement Exhaust

Is the replacement exhaust manifold 1-984054 reqiure the Mounting Kit for 984054 Manifold? Are they longer than the orginal bolts? The reason I am asking is the replacement manifold bolt holes are not the same as the orginal. They are not recessed for a socket to fit to tighten. I can send pictures if it helps.

Answer

You don’t need to order the mounting kit unless your old bolts are in poor condition. No difference, these are tight and you need to use a combination wrench on most of the nuts.
