I heard that replacement exhaust manifolds for the omc 3.8 litre engine will hit on the motor mounts if you have the select trim style mounts is this true.

We have a replacement Exhaust Manifold Kit that will work for your engine - and the mounts.


Question

Looking for a manifold kit OMC Chevy 3.8 Litre,Model 382SPMRCRJ, Serial J799555. Do you carry a manifold for me?

We have an Exhaust Manifold available along with a Riser but connecting this exhaust up to your Y-Pipe will require additional plumbing that is up to you to design.

Question
I can't find manifolds anywhere for my 83 OMC 3.8L

I can’t find manifolds anywhere for my 83 OMC 3.8L is there a conversion that will fit my boat? It says they are obsolete.

Answer

We do have a set of generic Exhaust Manifolds and generic Risers that will bolt up to the engine but getting the exhaust to the Y pipe or straight out the back of the boat is up to you. Sorry but everything else is obsolete.
