Re: Force 120 HP Broken Left Fin on Gear Case... Help!
Lets start by clarifying what "fin" has broken. Are we talking about the large horizontal anti ventilation/cavitation plate that is just above the prop? How big is the missing piece? Is it from along the back edge, the side, etc.? If its a very small piece, you may be able to leave it alone. If larger, but would not interfere with installation, you might just ad a Doelfin hydrofoil to your motor to restore or improve your motors performance.<br /><br />Also, where are you located? Someone here may be able to recommend a shop near you.<br /><br />I don't know which manual you have, but its good that you do. What year is your motor? If you have the Clymers manual, then on page 442 there is a diagram of the lower unit for '95-'99 models, 120hp. Rest assured that all the parts you see in the diagram will come out as a unit, still attached to the lower unit. This includes the driveshaft and the shift shaft, and the waterpump assembly.<br /><br />I would remove the prop and trim tab, then drain the oil, then remove the lower unit. Leave everything else intact, atleast until you take it to a shop to see what needs to be done.<br /><br />You can use this "opportunity" to install a new water pump impeller, which you should do every year or two, regardless of amount of use.
