If your motor is having issues, the fix is not in a bottle.

I have a 50/50 success rate.

posting your motor model info might help.
and it is hard to tell if you really know much about your motor since you think it has carbs

It definitely DOES slowly dissolve a buildup of varnish and other modern gasoline deposits. That is how you SHOULD USE IT !! Not 5 or 20 times the rated amount in EFI systems. You do not want bits of build up suddenly breaking off.
I do a 1 time each year with a 6 gallon tank and Seafoam mixture in it. Never a huge miraculos engine change.
I am in a 6 month winter storage area. I do not use special Yamaha P M solutions at put away time. I just have the fuel shut off and engine run dry. Done Disconnect positive battery cables.

Why the hell does a bass boat need to do 60mph let alone 80 ? and need 300hp .Anybody doing those speeds around fishing areas here would get their pedigree read to them back at the ramp .
To be fair its a nice looking boat and Im all for horsepower, but on a fishing boat .

M 50 hp pushes me at 32 mph max, on my lake end to end saves about 10 minutes....
