If they have 87 and 93 , I'd take a 1/2 tank of each - that's 89.......and don't listen to the web for this - call Yamaha and ask....many people use Yamahas in the bahamas where there is nothing but 87 and they seem to do fine. I suspect you'll be fine at 87 but call them. Make note of who and what date you communicated with them. An email from them would be ideal for your records.

My nieghborhood marina only sells 87. The boat stays on a lift and trailering to go get fuel is a pita. Dealer stated that it would not damage the engines, just loose a little performance. The one time I have refueled has been at another marina on the way out. And their choices are 87 or 93. Looks like these 250's will get 93....

Will it cause damage - Maybe, maybe not.
Can it cause damage - Yes, absolutely.
89 minimum octane is required. Why would anything less even be considered?
And the new boat is awesome
Damn, I hate to agree with Glen but "here I go again".
Just mix the two grades of fuel as he suggested and you should be fine. I also suspect that if you use grade 87 that you will be fine but what if my/our suspicions are wrong? You will be the one paying the price, not us.
I have seen engines that have run fine using a substandard gasoline. But then I have seen engines that were run on the specified grade of gasoline with holes in the tops of the pistons when the gasoline was old and maybe had lost a point or two or its octane rating. Couple that with a prop that is too large, a hot day, an operator that jams the throttle wide open and you might have a receipe for disaster.
My doctor mandates that I take Prozac four times a day to calm my homicidal tendencies. Do you think it is OK to reduce my meds to just one a day based on advice from a website?
After all else fails, follow the manufacturer's instructions. Good luck with the new ride.
