My neighbor has a Bayliner boat, that has a Volvo Penta AQ-125A motor in it. the timing belt snapped, so he wants me to replace it. But, im not sure if there is anything specific I need to do when changing it so it runs correctly since i cant seem to locate a FSM online for that motor. Does anyone know any info about this motor at all, or where i can find it
