The problem we have is that 89 here is always an ethanol blend, so it's either 87 or 91.

I've never used anything other than 87. Didn't even know 89 was recommended. Here everything has ethanol in it.

I've was checking out the new indmar site and it looks like all of their new 330hp and 345hp are designed for regular unleaded.

I also checked out the web site and noticed in the pictures of the engines they have changed the exhaust manifolds. Yes they now have cats standard, but the tubing from the heads to the cats is no longer water jacketed. Along with some other evolutionary changes.
On mine, Indmar calls for 89, I usually run 87 w/o any problems. I may run 89 or higher towards the end of the season to get the enthanol level down in the tank. The higher octane stuff is usually ethanol free depending on the station.
Currently regular 87 is $3.50 gal. I hope it stays under $4 for the summer.2003 Outback, Assault EFI, (6) Polk Audio DB651s, JL Audio M6600 amp, JL Audio M1700 amp, JL Audio 10w6v2 subwoofer

I hope it's under 3.50 as well. If not- I'm not going to be so excited filling up all of the ballast every outing.

I find it odd that the higher octane fuels have less or no ethanol content in some of yalls states. Ethanol has a higher octane rating than gasoline which is why some E85 vehicles generate more horsepower with E85 than they do with regular E10. The higher octane rating of the E85 allows them to advance timing and squeeze a few extra hp out. I would think that 91 or 93 octane gasoline would contain just as much ethanol as 87.
