Re: yamaha 200 HP OX 66 saltwater 2 series
 

I am happy with the numbers you gave me.The boat I bought has the OX 66 200 and it only has 27 hours on it.I bought the boat at a low price so figure that will make up for a little x-tra fuel burn.Thanks again for the info. Keith

what grade fuel do you burn,I do not have a manual for my 200 OX 66? Thanks Keith

I burn regular gas 87 octane. I get it at whatever gas station is cheapest. If your motor is new make sure it has been back to the dealer for the 10 hour service. That is the one where they reduce the oil useage to normal. The owners manual is available as a pdf from the yamaha website.
