That it has an engine!

[luderick74]

dont worry about those silly people saying does it work? does it have an engine? etc. the most important thing is does it FLOAT

[Evan]

does it run and float also how old it is, is it in good condition, maybe try it before u buy it to see how fast it goes for ur money pretty much the same things u would go over before buying a car

Check over the whole jet ski look for cracks on the bottom. Check to see that the impeller has no nicks or chunks out of it because it could be a sign that the jet ski was run in too shallow of water and sand could of gotten into the the cooling system. Make sure that all the maintenance was done on time. Make sure it was winterized when it was put in storage. Pay more attention to the amount of hours it has been used more than how old it is.
