Force Warped exhaust port plates?12'er

[dmessy]

Noticed your comment on Force outboard reliability and am curious as to what causes the plates to warp, what are the syptmons, and the cure. Thanks..

I dunno why, but there have been many posts here on these motors getting water in the lower cylinder. The gasket on the exaust port plate lets go,due to warping. Maybee due to very drastic water temp changes when the thermostat would hang closed, or running the engine without one.By many posts, i mean 4 or 5 individual posts.Pull the lower plug,and compare it to the others. If it is very new looking,or cleaner than the rest, it indicates water in the combustion chamber under operation.If it look like the rest of the plugs, don't let it worry you,as it's good to go.
