Re: Wrong Prop?
First, check the tilt pin hole. The tilt pin should be in the hole that most closely approximates having the cavitation plate level or parallel with the hull bottom. If the engine is tilted too far out, it will have trouble getting the boat on plane. If it is tilted too far in toward the transom, the boat will jump up onto plane but top speed will be low.
That engine should be able to plane that hull even with the incorrect prop. I would expect a top speed of somewhere around 20-25 MPH at plane. They only made three props for that series engine--35,45,55-- and 13 1/2 inch pitch X 10 3/8 diam. was the biggest. Even with that prop, that engine still should be able to plane out the average loaded 14 foot boat. But remember: most boats will plane at somewhere around 15-18 MPH. If you are not acheiving that speed because of load in the boat, It just ain't gunna plane.
So, you also need to check the hull for a "Hook", check to see you are not carrying water insude the floor or soaked into foam.
You also need to check to see that the engine is getting enough gas (fuel pump), that the carb is opening fully, and the carb and timing are synchronized. If the engine picks-up and gets on plane when you continually squeeze the primer bulb, then the fuel pump diaphragm needs replacement.
