Manifold leak

[bcontento]

I have a 1972 Evinrude 40 hp (a bunch of you just helped get my no start issue resolved). Got it running and now there is a bit of a manifold leak here. Is there an easy fix without pulling the entire front off?


I can see a little vapor of some kind puffing out there and every little while I get a pretty good burst out of that spot. Kind of like a backfire.

Yes that was of course the first thing I tried. They were loose. They're old crappy screws. I'm thinking of taking them out and replacing them with bolts that I can put a little more torque on.

They made thousands of these motors.----No need for better screws at all.----Replace the gaskets.

they need to be torques to specs...and do not strip the threads on the block!! !!

Unless of course the Flathead screws are 50 years old and putting a screwdriver on them well is virtually impossible.
