While I gained about 400 rpm from the top end kit (aftermarket heads, roller rockers, intake manifold and camshaft) and had very good hole shot but was not any faster with the original OJ legend 13x13 4-blade. I was left feeling there was still more on the table, after the prop change, Acme #541 13x12 cnc 3-blade it had even more hole shot and was even faster (47mph@5000rpm)
Agree 100%. The intake and heads are a great combo upgrade after the prop. But since you already have gear reduction, you already have plenty of grunt out of the hole.

To me, this forum is about love of inboard boats. It is about the sharing of information and, on a good day, some humor. It is not about post count, brand of boat, or any other superfluous labels that lend themselves to a false sense of superiority. Please, respect one another, try to pass on accurate information, and keep your eye on the ball.
