1976 Mercury 650

[jconrd82]

I have never owned a gas engine boat, but just acquired a 1976 Glastron Beau Jack T169 Wednesday. The previous owner stated it runs fine until your get it at full throttle then it tries to bog down. He stated you have to go back to neutral and full throttle to keep the rpm up. One of the blades on the prop is also bent and needs replacing but I could not find the correct numbers and do not know the proper running RPM for this motor to know which pitch prop is needed. Any info would be greatly appreciated.

Did you look under the prop nut for numbers?
You should be able to get the prop repaired at a prop shop.
Be sure the motor is not over heating.Bogging could be all most anything but start with changing the impeller (water pump)Then check the fuel system.Timing is critical can cause all kinds of difficulties.
