I have a 2010 Yammy 25 2 smoke with a Power Tech SRA 4 10" 10 pitch prop on a 14' catamaran hull that at WOT is at
4500 RPM's on a Tiny Tach. I thought it may be the prop but a thread below has me thinking it may be a fuel line issue. The motor has about 15-20 hours on it so it is essentially new. Thoughts?

What type of speed #'s are you getting? Reason I ask is because I run the same exact motor and prop and have no issues with rpm's or top speed. Someone already did the research before I bought the rig though..

I was getting 18 -20 with the 4 blade and 22.5 with the stock prop with CMC TnT and a SE 200 fin.
