SeaDoo GTX Fuel Recommendation

[slevar]

My 2014 GTX 155 Operator's Guide states: GTX and GTX S Models: Use common unleaded gasoline with an AKI (RON+MON)/2 octane rating of
87. [Technical Specifications state: Minimum 87 octane] The GTX 155 engine is a normally aspirated high compression engine (10.6:1) Other than the additional cost, is there any reason I should not use 91 octane fuel?

No, but it won't any noticeable difference.

It shouldn't do anything "noticeable", but it's more healthly to use the gas your "operators guide" tells you to use.

i run regular in my 210 challenger with the 215 supercharged engines.... it has not problems at all.... the sticker on the side of the boat next to the gas cap says to give it 87 regular

Keep feeding 87 and you should be OK......unless you start to mod the motor.

Adding 91 octane will not give any performance gain, do not waist your money.
