    Burnt Alpha One Gear Oil Thoughts

I recognized the burnt smell, 1. because it is not normal, 2. we have two seadoos and when we change the jet pump oil if the kids ride hard all summer it will have...

    Where does throttle body muffler go?

    Where does the little square muffler go? Ordered it and matched part number from merc but I do not have one to replace. The diagram points to a oval hole for a square piece. I tried uploading a picture but can't. There is two oval slots and one looks like a piston slides through.

    Any special considerations on removing ECM

    I need to remove the ecm for a 2014 4.3 MPI to get access to the dizzy cap and rotor to change them. Just remove power and unhook all connections? Will the boat run rough when everything is hooked back up like a car until it relearns everything?
