    Question 94 - SLT - At The Crossroads

    Very short history
    rebuilt carbs and upgraded fuel system. all new lines. took it out & burned a hole in PTO piston. Pulled jug - looked great so I ordered piston. In the meantime, I split case to change seals. Found the both journals on the back rod (pin and crank) were discolored - obviously had been hot. Pin bearing still looks and feels good. Spinning the rod around the crank, you can hear it just a little bit whereas the other two are silent. So here is the dilemma, looks like a crank is gonna run around $250 on exchange plus some shipping. I have a $100 gasket set and a $100 STD bore piston that I am stuck with. Change the crank or just part it out and chalk it up as a loss? Already spent the $150 on the carb rebuild with Mikuni stuff, plus the triple outlet fuel pump. Ugh! Decisions, decisions...

    probably should go ahead and fix

    Not a whole lot of demand for 750 parts, parting out might take forever and there is a very strong possibility you will be stuck with a lot of leftover parts. If the alternative is to go and buy another PWC to stay in the sport, it seems like you are very close to having addressed almost everything that could happen with this one. If your SLT is in good shape cosmetically, I'd probably go ahead and fix it.

    It's a boat...of course you keep putting money into it!

    Just think of it as a summer's worth of gas.

    any preferred vendor around here?

    I don't know if they are preferred necessarily, but SBT would be very quick and easy, and it does come with a warranty.

    Before I do that, has anyone had any luck taking the crank apart and replacing one rod?

    Crankshaft repair/rebuilding is not something that lends itself to being done at home. Even the most experienced forum members are probably going to echo me telling you to have that done professionally.

    Need a hydraulic press. If you have one, and precision alignment equipment, let us know....

    You'd spend months making jigs to do this properly.
