with OMC, Merc, Volvo I/Os. (with an odd ball or two thrown in)
The exhaust manifolds have seen years of use and bad winterizing jobs.
"A leaking exhaust riser gasket can destroy your engine"
This cheap and easy to replace gasket causes many an expensive repair bill.
As they age and the manifold to riser mating sufaces rust they start leaking exhaust
cooling water into the engine cylinders. Since water can not be compressed even
the smallest amount can severely damage an engine.
"This is an good couple hour job for the backyard wrench turner"
1-Go easy removing the bolts a little light torch heat may help.
2-Clean the mating surfaces very well (VERY WELL)
3-Take a good look in the manifold and riser
(A crack with rust around it means you need to replace the part)
