Thanks. Battery was dead so no MPH. I'll have to go out again to get some hard numbers.

General rule is 200 rpm decrease for every 1" of pitch increase----with the same make of prop.

Well I ran a 26 Bravo and saw 82 GPS @ 5300. At this point I would say this is the prop for me. But I am still open to suggestions on what else to run. Thanks.

Labbing a 28 is another option that will put you in the same rpm range (5200ish). Your current efficiancy will help to determine if Labbing is a good all around option. Your gear ratio will help to make the determination.
