it is very clean. Looked rougher under a thick coat of dust, dirt, and bird doo doo. After talking to the guy for a min, he told me it ran fine, then he put it away for a while. When he put it back in the water and it made a knocking/rattling noise but still ran good. He took it out and started it on the hose and it was doing the same thing but louder. He assumes the engine is bad. Personally I'm hoping for a pump bearing making a racket back there. I guess I won't know till I charge or replace the battery and drain the leftover fuel (been in there 3 years) and crank it to see what happens. I'm hoping for the best but expecting to pull the motor. It would be sweet if I scored a ski that needs a pump rebuild for a whole lot less than $500. Yes I got it for less than that and that's all I'm saying on that subject.
