HI, <br /><br />We have a Godfrey Deck Boat with a Outboard 115hp Yamaha engine. Big problems, it will not engage in forward or reverse. Any suggestions for repair ? Also, any good site for repair manuals or troubleshooting ?<br /><br />Thanks

It's my understanding that Yamahas never break down (!), so I would check the cables and linkage first (control/shift box? connections at motor?)<br /><br /> Curt

If you can rev the engine but it won't go in gear then the linkage sheer pin has probably been sheered. Check your manual for location and proper part #.

Re: Yamaha 115 problem

I also have a Yamaha 115 that had some shifting problems.<br /><br />I recommend that you try the following:<br /><br />1. Disconnect the shift cable in the upper unit and verify free movement of the control box.<br /><br />2. Reconnect if good, and have someone watch the shift linkage for rotation when changing from forward/neut/rev. This can be seen in the opening on the upper unit.<br /><br />3. If rotation is good, then drain the gear oil and rub between fingers for evidence of metal shavings (also look at the lower screw, it's magnetic and will trap some particles.<br /><br />4. After you remove the gear oil and evaluated, drop the lower unit and inspect. If particles are found, this is not good and you might need to repair the gears in the lower unit.

remove the cowl from the engine and look just to the rear of where the cables go in you will see two cables that actuate the gearshift and the throttle the lower one is the gearshift.<br />shift the remote box into forward and the cable should move the shifter forward maybe have some one shift it for you so you can watch make sure it moves right forward and back to the middle to get neutral and then right back for reverse.<br />if you notice a clacking noise coming from the gearbox and have verified the shifter is working it maybe the shift dog in the gearbox jumping.<br />(bad news)<br />another thing to check is the arm that runs right down to the gearbox and turns to activate the gears its possible its broken or has even been not installed properly if the gearbox has been off recently.
