The prop says powertech on it but there's no information about the diameter or the pitch. It's on a 24 outlaw with a 454/B1. I'm seeing ~60 mph at 4400 rpm, which seems a little low. Can't you safely turn the old carb'ed 454's around 4700-4800? The boat planes just fine without any help from the tabs.

Any of you guys know what the specs on that prop are from the photo? Or if it's optimal for this boat at this power level?

Had these lying around. Got more, but they should give you and idea. Most are 4200-4600 and the mag ect. are higher. Got others, but these give a pretty good idea about them.

Hope this helps

Look at where its stamped PowerTech and there should be a long string of numbers and letters with the last of that string being the pitch ie. xxxxxxxxxx24P
