Do you have flappers on your exhaust? People are commenting on reversion, that can very well be a problem but it seems with these Eagles when you come off plane the backwash will try to shove it's way up the exhaust. I even adjusted my driving to compensate because the vents above the swim deck would become an open faucet to fill the bilge. When they dyno'd the engine did they use wet or dry exhaust? I take it these pictures are of the dead old engine not the new problem one is that correct? Randy

Those manifolds are prone to reversion. Early HP500's used them and they had a raft of problems with them. Anything over about 230 deg.@ .050 and they reverted. Merc went to CMI exhaust shortly after.

Yea every boat has it's quirks & that seems to be one of the eagles but dang they are fast so I can live with it. Is there any new info? or was reversion the problem? Randy
