I bought my second 3D today. It's a 2005 premium with 45 hours. The boat is in decent shape but spent some time being stored outside. For the price it was worth it. The original owner was an older guy and had many other skis and toys. He had a recent receipt from a BRP dealer showing the hours and he seemed like a decent, honest guy. He told me it was taken in for service at the dealer before and after each season. After getting the ski home today I started my pre-ride rountine. When I drained the jet pump oil.... the fluid was dirty and as thin as water. I have changed a few of these now and never seen the fluid so thin and "used up" before. The pusher part even has a small burn from the shaft. I plan to replace many of the cheaper plastic parts and etc...but i'm a little worried about the bearings. I want to flush the system a few times to clean out the old oil/grime, and then refill it. The Sea-doo brand jet pump oil is is rather expensive. I don't wanna spent $60+ on fluids to dump out. The Sea-doo oil is sythetic SAE 75W-90. My question is...can't I just use another brand 75W-90 oil? Amsoil makes this weight oil for gears/bearings. I can get a qaurt(32oz) of Amsoil for $10 or 6oz of BRP for $15. Has anyone used other brands of oils?
