    Drive Shaft Wear Question

    Since my ski is no longer under warranty I'm forced to do my own repairs. Nothing wrong with that, kinda fun really, but it's still new to me. I pulled the drive shaft today, going to be replacing for other reasons, but I noticed some wear around the shaft where the carbon ring would be, and also uneven wear in the carbon seal. Is this normally seen from initial wear in or something to be concerned with? This is a 2010 RXT 215 stock with the updated drive shaft. No unusual water present in hull (I sometimes ride rough so some gets in anyway). Bottom of hull is gray from carbon dust after 55 hours on this carbon seal, but his is a wear item right?

    You need to check motor-to-pump alignment and more importantly, pump-to-thruhull housing alignment.

    ps. Check to make sure rear motor mounts are good.

    Thanks for the quick response!

    Two follow up questions for you...

    Aside from an obviously loose engine mount, how and what should I be looking for here?

    Also, I'm aware of the engine alignment tool, but how would I check the pump to thru-hull alignment?

    Thanks for the help...I did a search but was too lazy to dig so deep.

    Going to have the alignment checked by the dealer, but I have had two alignment checks done previously and I see no signs of a broken mount or shifted mount. I'm leaning toward the possibility that the bellows may have been clamped to the thru-hull at an angle. We'll see what the result of the alignment check is.

    Get the tools and do it yourself. This is a classic case of the engine alignment being out and a dealer cant be arsed to go through the time intensive process of doing it properly. My 2 cents anyway.
