This is already being handled through the dealer. Yamaha's standard protocol is to have the owner continue running the boat and check back in 100 hrs and to NOT do an oil change for 100 hrs. I'm thinking they have some % of fuel dilution they deem acceptable and they can't respond to every complaint of "making oil" without seeing a sample of oil that has gone through a full 100 hr cycle. My hands are tied. I just have to do what they say and let them respond accordingly.
