1979 Johnson 115 HP - Oil/Gas Leak

[pkimball]

I have ran this boat I recently purchased a few times, but notices some oil/gas in the water. When I stored the boat I came out to this a few days later. I don't see anything directly when I take off the cowel. Any ideas where to start looking?]]

Gasket between powerhead and exhaust housing is my guess.

Thanks. Do I need to basically take it apart to access that?

I can not see or touch your motor.----On this 45 year old motor I would first do a compression test.----Post the actual values here.-----The powerhead is removed as an assembly to change the gasket.----Factory gasket today is improved over the original one.
