I just bought a 2015 mercury 25hp 4stroke 1.92 gear ratio. It has a beat up Merc 9.75 x 9.50 AL prop that pushes the boat well. It runs 26-28 mph at 5700 rpms. I am happy with the performance but I think I might can get a touch more out of it. I need a new prop because this one is pretty banged...
2002 Yamaha F115 runs fine for a while and then starts to back down. I can shut it off and it will run fine again for a little while and then starts to bog down again. It has progressively gotten worse. After doing a little research I suspect a clogged VST any ideas before I start taking it...
