Hi out there! I'm new to the Sea-Doo. Well I'm new to boating! Lol. Anyway. I just bought a 1998 Sea-Doo Challenger 1800. I'm very excited and can't wait to get it in the water. Any suggestions on maintenance would be greatly appreciated. Another thing. How think is the haul? I'm looking at putting a wake tower on it but it requires at least a 3/8 haul. Does anybody know. Well that's about it. I'm ready to have some fun on the water.
