I have a 2001 XLT 1200 and I have a problem with it. When I try to give it throtle (in water) it seems to rev and die out. We an almost seem to work our way up to speed gently but when we get on it it just seems to spin. We think its a prop problem but we wanted to get some verifacation before we bought a prop for it. Any iformation would help us greatly. Thank you.
