Hi I have a 1975 25 hp Johnson that won't start. When I turn the key, the starter engages but wont turn the motor over. It will not pull start either. I just bought this boat and it worked fine the first 2 times I had it out. I have already replaced the battery. I am new at this but wanted to try to at least make an attempt at fixing it before bringing it in somewhere. Thanks |

look for a big nylon-plastic pawl on the starbord side of the motor near the rear- watch while you shift F-N-R how that pawl grabs and locks the flywheel from turning in gear...then check how there's a nut that can be used to adjust it so it gets out of the way in neutral |

That wasn't the problem. I checked it out and the nylon pawl wasn't stopping it from turning over. |

Is it possible that the motor seized from lack of lubrication??? Are you mixing gas and oil at a 50 to 1 ratio?? Does the flywheel move when turned by hand??? Pull the plugs and check for any rust. A leaking head gasket can let in enough water to rust the cylinders. Did the motor run this season or did it stop running after a period of storage??? |
