HI i am new to this forum.little story:back in 2001 i buy a new baja 272 with a 496 MAG,very desapointed with performance about 57 MPH at around 4600 RPM on GPS,bring back the boat to the dealer several time,the final answer was that i have a slow boat and it appen sometime.i instal a HO cam and ECM the same year,little better about 60 at 4800.all with a 23 mirage +.later i instal a 22 bravo1 boat is a bit slower but ride is better.this sprink i decide to change the spark plug with the same number and brand,WOW now i turn the bravo 22 at 5150 on the smart craft and tack at 64.7 and the mirage 23 at 66.2 GPS at 5050 RPM??????.my first question is i like my 22 bravo it is smooth and good holeshot but it rev to mutch now the mirage i about OK but dont like it.what prop should i buyto bring down the RPM at about 5000 .2 at 5150 there is a beep alarm on the boat is it because it over rev.3 at idle in neutral the engine is not stable up and down i can ear it suck some air and stop and again.....is there something i can do for that thank any help will be apreciate.

PS all the spark plug removed have a gap at .080 instead of .060 do you think it was my problem

I would have the 22 B1 worked to get the rpm you want. You may want to put this post in the prop section, and see if someone there can help you better.
