Another thing to consider. Engine Nut, who works for Indmar, once posted here that the reason Indmar called for 89 octane was due to the fact that most people use their boats infrequently. 87 octane is fine, but 86 is not. So, to avoid having people fill up with 87, then leave the boat sitting for a month or two between uses and starting it up with what was no longer 87 octane fuel, Indmar recommended 89 octane so that there would be a little buffer for less frequent users.
I think it is a good idea to stabilize any fuel you don't intend to burn off in the next two weeks before that last outing of the weekend.

To me, this forum is about love of inboard boats. It is about the sharing of information and, on a good day, some humor. It is not about post count, brand of boat, or any other superfluous labels that lend themselves to a false sense of superiority. Please, respect one another, try to pass on accurate information, and keep your eye on the ball.
