Shane, that's good news for me! I only ever changed oil and filter once a year (+/= 100 hrs) on my 99 RLx. The oil is always visibly clean so I just couldn't see the point. Been using Amsoil Marine & Diesel 15w-40 and it gets put away for winter with fresh oil. Also change the tranny fluid, which seems like overkill but since I'm already into it, why not? The boat has +1000 hrs and maybe changed plugs every two or three years, wires once, cap twice, impeller and fuel filters every year. Other than that it has just been replacing things like a bad fuel pump, failed relay, etc. Wish I could figure out why the depth finder kills Stargazer. I tried all kinds of fixes and ended up installing a switch to turn it off when not needed. h2dawg79, I think the fresh oil thing had something to do with acidity, not oil breaking down. My opinion is that the toughest thing on an engine is sitting in storage so I figure it can't hurt to schedule my annual change for the fall. My boat is storage for 7 months a year!
