Hey guys -

I am probably just being paranoid, but I have a fuel octane question. I have the 6.0L 409 HP Indmar engine and the owners manual says to run fuel with a minimum of octane rating of 91. I have about 40 hours on the boat and I have done this to this point. We are going on a trip and will need to fuel on the water, and based on a few phone calls to marinas on the water most carry 87 clear (no ethanol). Is there any risk in running a tank or 2 of this through my boat?
