after you treated the gas did you refill the tank with good gas?

Our boats should run on 89 not 93. 93 is to rich.

Octane allows the fuel to hold out longer without blowing up, preventing detonation and backfire, so combustion occurs only when the spark is present.
Additional octane does not hurt, but there is no improvement unless the engine can accommodate the higher octane and adjusts timing for it.
Mixing octane will average it out (notice at the pump there are only 2 tanks but 3 fuel grades sometimes? They mix it too)
Putting high octane fuel on the boat is not the cause of your problem. Look elsewhere.

The supercharged engines in the 192/195's according to the owners manual need a minimum of 91 at the pump octane number.

I put a bottle of the red heet as well as 1 1/4 bottles of sea foam in the fuel tank and since i bought it 3 weeks ago I've only put 93 in it. It is running much better had no issues today. I'm thinking I might have sucked up some crap from the bottom of the tank and clogged an injector.

Thats great it takes some time for the RED to work and the addition of the NEW fuel also helped great news! If the PO did not use 91 octane thats a problem also if the gas that was in the tank was a ethanol gas it will separate into two different structures so the addition of the RED and the seafoam will take care of the "water" that separtated from the gas..

I guess when they changed the SC for the 195's the Octane requirement changed...Good to know!
