Oil Pan Leak on a MR-1 Engine
I have a couple of naturally aspirated MR-1 engines that both have a slow leak at the oil pan gasket. I ordered a new set of gaskets and they are the thinnest pan gaskets I have ever seen. The maintenance manual does not specify a sealant, but I believe one is absolutely necessary to seal this problematic joint. This is in a Yamaha sport boat and I know of many that have had this problem.
Has anyone found a solution, or can someone suggest a good sealant to use on the gasket?

What are you using? The right stuff? Ultrablack RTV?
I am going to attempt to do this without pulling the engines. Going to be an upside down backache .
