Tried as a last resort... It worked!
Color: Blue, Number of Items: 1
My 3.0 MerCruiser stern drive was hard starting and would not hold at idle and ran really rough under load. I put 2 cans of S*Foam Marine through the tank and replaced the fuel filter and the spark plugs. With only a slight improvement I decided to bring it to my dealer. They replaced the distributer cap, rotor and plug wires and sent me on my way. The idle was good, but under load (headway speed) it ran really rough. Brought it back and they swapped out the carburetor and lake tested it. Back at home it ran great for a one-hour ride. A week later I tried to start it and the idle was bad again (engine shaking, erratic RPM). Almost dragged it back to the dealer but thought I would try this first. Per instructions I added this to about 15 gallons already in the boat and then topped it off with 5 gallons of fresh gas. Let it idle at about 1500 RPMs for 15 minutes and WOW, it's purring like a kitten. Next time, this will be my first resort!

It works!
Size: 16 Fl Oz (Pack of 1), Style: Individual
A short story long---LOL---My zero turn started acting quirky-it would not run at full power and would begin to stall when put under a full load - like trying to mow some taller or thicker grass- never did stall since I would immediately kill the mower but obviously it was not right. I checked and changed the fuel filters-this one has 2 . One in the pick up line in the tank and one is inline just before the fuel pump unit. No help! So, before I dropped the big bucks to have the local farm dealer come and pick it up (at $75 per pickup and return) plus h=whatever shop charges that would result I thought "What the heck, lets give this stuff a try" I gambled $6 . I put in 5 ounces for the 5 gallons tank, and filled it with the gas I had on hand- should have been relatively fresh gas -no more than 2 weeks since pumped . Well, whatever the cause of the issue within about 15 to 30 minutes of low speed running- mostly at idle - the engine seemed to be idling smoothly as opposed to before where it surged but never died, I gave it a try at mowing. YEA!!!! full power and no bogging down - I finished mowing the yard and a part of the pasture (not yet grown up much so it is not requiring the rotary cutter YET) My only guess is perhaps a batch of either old gas or some water in the gas can or mower tank but whatever the cause it fixed it --and all for $6.
