I added this to my Johnson V4 140hp outboard.y

I added this to my Johnson V4 140hp outboard. My boat sat for at least two and a half years, and I had been refused a service at a local location due to their policy not servicing any outboard older than 2000. I came across this stuff and I’m happy I did. I followed their instruction they recommended and I used a gas mix ratio I liked that made more sense for my needs after watching some vids I drained the old fuel and added the fresh gas mix, I had ended up needing to mist the air intake with gas to get it started taking several attempts. . Once I added I ran for 20 mins with muffs water supply then let sit for the night which was recommended to allow the Seafoam time to eat junk and lube and treat internal parts that may be gummed up. Next day I was able to restart 3rd/4th attempt with no support with fuel in the in takes it smoked a bit while burning off the junk but, now she starts up nicely around weeks later with 1st to3rd at starting is running nicely so I recommend this product and will use on a regular schedule now.. Thanks.

Your boat engine deserves to be treated with Seafoam Marine Pro !

If you own a boat you really need to use Seafoam Marine Pro in your fuel to get the best performance out of the engine. Also works to stabilize the fuel when the boat is in storage during the offseason. Try it and see for yourself!!
