Re: 89 Johnson 9.9 cooling system obstruction

quote BillW:

If you haven’t actually lifted the block off of the mid section yet (From your post, it sounds that way) then the toughest fasteners, the ones that hold the exhaust tube onto the bottom of the power head, are yet to come…..

While the block is off, you might want to give your upper engine mounts a fore and aft yank and see if they are solid. Failure of those uppers is the other 9.9/15 common flaw.

Excellent point….It may be easier to evaluate the mounts before removing the powerhead by rocking the powerhead fore and aft.
