Octane Booster?

[FLTENNHUNTER1]

The other thread about gas in our boats motivated me to research octane boosters. Do y'all use them in your boats and which brand is best?

Mercury quickly or seafood is all I use.

Are you sure these raise the octane rating?

Not sure if they raise the octane,but good for your fuel delivery system.

I agree with you there. I use Seafoam in my vehicles. Use Starbrite Star Tron in my 100% Gas applications.

Has anyone used Lucas octane booster or similar octane booster product? Seafoam doesn't increase octane.

Check your owners manual. Some outboards recommend not to use too high of an octane.

Yamaha recommends 89. I have used 87 since I purchased the boat new in 21. No issues so far but wondered how it would perform with 90 octane. Lucas claims a true 3 point increase in octane level.

There is really no need to spend the money on octane booster unless you have a rebuilt engine where they maybe shaved a few thousandths off the block or heads to increase the compression ratio. That and a timing change would be the only reason to spend the extra money on octane boosters. Now these new computer controlled motors might be a little different. If you have your computer flashed then an octane booster and 93 would probably help you out.
