gasket part numbers 4.3 omc

[ciera]

I am replacing engine in my boat 1987 4.3 omc with a 1991 4.3 out of a van I need to know what the complete engine gasket kit part number is and what gaskets I can use that are automotive ie exhaust and head gaskets I have striped engine down to check all internals

go to the local NAPA and buy an auto gasket set for the van. Fel Pro or other good quality one. Everything on the engine "long block" from that kit will be fine for marine.Then go to shop.evinrude.com to look up OMC marine specific gaskets for exhaust manifolds. You can buy them at any Evinrude dealer or cross them to aftermarket parts here at iboats (this site is not an Evinrude dealer)

That should be about it.

I thank you will find the Exh. manifold gaskets PN to be:
OEM 3853412
or
Sierra 18-2909-7

I just checked and our good old Iboat parts right here has what you need.
Just be sure to verify when you order.
Good Luck

oh, and you can get a Pioneer brand brass core plug set for a small block chevy V8 at a parts place to replace the tin ones to brass. Should be around $15-$20 for that.
