Johnson 1985 j10rcom 9.9 hp .

[Trow]

I have a Johnson j10rcom that has a leak at the top of the exhaust cover . Obviously i would like to change the gaskets out but it looks to me that the bottom right bolt is unreachable (underneath the motor mount .). Not to mention it looks like there is not enough clearance between the exhaust cover and engine housing to get the bottom bolts out . My question is do i need to remove the power head in order to replace the exhaust cover gaskets ? Than you in advance ! Tom .

I wonder if you are seeing some mystery spray when running on muffs?

Best to remove the powerhead to replace exhaust cover gaskets.

Apologies Trow. If you remove the powerhead as indicated, you might as well do the t.stat while you are at it, along with the t.stat cover gasket. Good time to do it conveniently.

On the exhaust cover and gasket, you might be able to remove the lower bolts with a small box wrench. You may have to back the bolt(s) part way out, then lift the cover and bolt vertically to get it out of the pan.
