I'm running a new Yamaha 25hp with about 10 hours on it. It's mounted to a 1990 1542 duracraft.
With me and my wife an turning right at 4970 to 5010 rpms on hardline tach. 20-21mph. That's using factory prop 9 7/8 x 11. What should i drop the pitch down to to get the rmps up to the 5500 to 6000 range?
Thanks for your help
