Just got this boat with 115 optimax. Not sure on the prop but when i took it on the water tach got up close to 7,000 and speedo showed close to 50mph. Engine did not seem to be revving that much but i will assume the gauge is right and it is WAY to high. This is a popular boat, anyone out there with the same rig and if so what is the prop to use? I will do 99% fishing and very little towing for water sports.
