    Considering replacing 9.9 hp gas with electric, I welcome anyone's input on the prospect of doing this

    Thank Fitz, will do. But I am still interested if there is ~9.9hp drive by wire engines on the market?

    Considering replacing 9.9 hp gas with electric, I welcome anyone's input on the prospect of doing this

    So the situation is this is a catamaran sailboat with two Yamaha 9.9 hp engines that are about 12 years old and pretty tired. I would say their replacement is in the near future, and this brings up the subject of considering electric instead of gasoline. In addition, because of the geometry of...

    Yamaha 9.9 tilt bypass valve location?

    Thanks for this, just taking a quick look at it it looks like if that 10 amp fuse is open, that would affect the tilting as well as alternator charging? See attached picture, I assume this is the fuse? Before I had this schematic and knew what it was, I assumed it might be a fuse and I fiddled...

    This is my second threat on this, and I think the simplest thing to do is just use the hydraulic bypass valve if there is one to put the motor down. Can anyone tell me where that might be located?

    Yam 9.9hp tilt quit, need schematic

    I dont have access to getting the model number but it is 4 stroke with electric tilt and start. What other options would be relevant to the schematic? I dont see an option to attach a pic I have of the top of motor with cover off if that helps?

    Yam 9.9hp tilt quit, need schematic

    Hi, I have a 2014 9.9hp outboard (2 actually) and the electric tilt has quit on both units. Unfortunately one of them is not all the way down, is there a manual hydraulic release valve that would allow it to go down? I don't actually need the tilt mechanism to operate, I just need to get this...
