1971 22-2 Semi V 200 Yami Inline 4s

[Capt222]

Hey guys. Brand new to the forum. I recently purchased a 1971 22-2 that was redone in 2013 powered by a 2013 200 Yamaha Inline 4 stroke. I am now in the process to dial in the boat with a new prop. I am currently running a Power Tech 15p 3b that is worn. My numbers are 26mph @4100 and burning 8-8.5gph. I am trying to tighten the gap between the mph and the rpm. Any help appreciated by similar setups. I have read people really liking the merc Rev 4 in a 19. (I was thinking of starting with a 17) as I do inshore fishing charters and still need to run fairly skinny. Thanks in advance!

 Welcome to our forum!
First year for the semi V was 1972 but you said she is a 1971 so it is a flatback or 12 degree V? Sounds like you are propped a little light with a 15 pitch, what is your full throttle rpm's ? Those engines twist pretty high like 6000-6100 RPMs.

The title says 1971 but could obviously be wrong. The hull is 12* V. If I could figure out how to minimize my photo size I would post a pic.

Upload your photos to the Gallery. You do not need to resize. Then you can post them in your thread and they will be auto sized. Painless.

Read carefully.
