    ive been reading the different threads on oils but not finding much on my question. Whats the best oil for a 525sc? I do a fair amount of idling due to NO WAKE zones if that makes any difference

    Why would the oil change based on the motor? Amsoil or Royal Purple are great. Use a good oil and you will be good to go. I would go with Amsoil with a Amsoil racing filter more sq in. of filter media.

    my other boat and my vehicles are stock engines..wasnt sure if it would be any different with the supercharger since some oils say that they are better suited for supercharged or turbo motors

    For as little oil as they hold, I would change it more often, than what they recommend. These blowers have a tendency to fill the oil reservoirs with gas, when the seals start to go. Changing it frequently, assures you to catch any fuel in there before any damage to the blowers. I quart of gear lube will cover both blowers.

    I used a little pump that hooks to a cordless drill. Sucks it out, and put fresh in. There is a front and rear crankcase on these blowers.

    Me, I'd change it every 10-15 hours. Some may say overkill, but for under 10 bucks, and 15 minutes of time, worth it. Those little blowers work hard.
