    Redo pump shoe or not?

    Im aligning my engine right now. The alignment tool goes right into the PTO with out any resistance. Where the alignment tool comes through the hull is not perfect. Its close. I measured from the alignment tool to the through hull fitting at four different spots each 90 degrees apart. Measurements are as follows. Top of throu hull to tool 9/16 in. Bot through hull to tool 8/16 in. Right through hull to tool 7.5/16in. Left through hull to tool 9/16 in. So do I need to pull the shoe and by a new one and align the shoe perfectly or is this close enough? Could not find any specs for it in the manual. Heres pics. Thanks

    One more. I dont want to do just to do it. Only if its off by to much and costing speed. What do you guys think? Merry Christmas!!

    Maybe I'm misunderstanding, but wouldn't shimming (or removing a shim) the engine/motor mounts correct this?

    EDIT: Or is the pump shoe set more to one side than the other?

    The pump shoe being slightly off is whats causing the shaft to be slightly off center in the hole. The engine is in alignment with the shoe. Just wandering if its worth redoing shoe or not if its off this small amount

    Yeah, I reread it and then editted my post. Misallignment has to be causing wear somewhere! I understand the undertaking, but the details in this hobby must be considered! I would hate to do it myself, but I think I would, especially if I plan to continue modding.

    Maybe someone with experience can chime in and say just how much speed is lost here, AND what parts would be prone to wearing. My guess is the splines at driveshaft/PTO and driveshaft/prop. I'm not sure how much play is in the seal, and if the seal would wear.

    EDIT: Check splines on prop

    IMO. If speed is your concern I'd be more concerned with the alignment of the pump in reference with the keel. I would hate to see you do more harm than good. Judging by the speed your running now and without seeing it in person, my bet would be the actual part of the hull where the according boot mounts is what is misaligned. I have personally shot one of those lasers from the hardware store down the center of my pump to make sure it was in alignment with the keel. Hopefully one of the smart guys on here will chime in and tell us more.

    I agree! I wouldn't mess with it.
