Hello,
Recently purchased a 290CC with twin Mer 300's. I bought the boat last year from another member of this site. Running WOT I'm only getting around 5400 RPM from both engines with a max speed on the GPS of 45MPH. It seems off from looking at the performance bulletin's that Sailfish puts out. The props are 3 blade SS Mercury mirage plus, I don't know the pitch off hand.
What are all you 290 owners running for props?
Thanks, Rich

Not to sure about Mer 300 but I do know you should be getting 5600 to 5800 RPMs. Your WOT seems low that boat should hit 50 + all day long.

That's not right. Pitch of props would be helpful.
Are you trimming the motors to maximize speed and efficiency? I suspect your over propped.

Definitely not set up right. I’m getting top end of 54 with Yamaha 250’s.
