    You have to make sure you have the correct adapter to exhaust plate. Thats exactly the problem we had in the 2.4 black max. The guy that put it together used a 2.5 adapter plate on a 2.4 power head and mid. Burnt the engine up.
    Respect no wake zones!!! Evinrude guys need a place to race too.

    sorry, but that alone won't do it.... as long as both halves of two piece or either 2.4 or 2.5 with right gasket in-between.

    Forgot to mention the lower plate was a 2.4 plate. It was 2.4 power head, 2.5 adapter plate into 2.4 exhaust plate. It did not line up at all. If the 2 plates were the same if would be fine, ours however was not. Crazy how you can bolt the wrong thing in there, bolt patterns were the same.
