Re: [OMC-Boats] OMC-Boats Digest, Vol 17, Issue 9

I see no reason why you can't make your own gasket - all you need is the
proper material and a template such as the old gasket - it is not rocket
science - you can buy sheets or rolls of any kind of gasket material at
NAPA. You will have to determine what material to use and the proper
thickness - the guys behind the NAPA counter usually can help or any oldtime
mechanic. I would not try to make a head gasket which is metal etc. I have
made many gaskets. Use an Exacto Knife or other razor sharp knife and or
scissors and I use can lids etc to trace larger holes and have a leather
hole punch set to do the bolt holes. The Seloc manual suggests rodding the
exhaust water logs as they scale up with rust over the years. Did they ever
check those? Good luck! TK
