Shock Treatment with Ring Free

[TSCTSC]

How should shock treatment be done exactly? Is it done in the water or in a tank? How much gas should be run through it? Is it recommended to perform this treatment? Thanks

I just did it to my 150 Susuki 2 stroke. it is a 2003 that I bought new in 2004 and it spends alot of time in the garage. the manual said to break in the motor with oil injection AND mixing the fuel in the tank 50:1. I have had a lot of problems with running smoothly since then. Following Pierz Marine's advice, I used ring free, did the shock treatment just as described on the bottle and ran from Isle to Cove on MilleLacs a few times and it made a world of difference. A friend of mine "shocked" his 98 Yamaha V-max 150 2 stroke as well and had nothing but good things to say about it.

So you just put the ring free in the gas tank in the prescribed amount and run through the whole gas tank on the lake till it is empty? How long is that going to take? Or how long should I run it? Then what do we do after that? Thanks

i did a whole tank just because I knew the exact amount of gas a full tank gives me. I thought the bottle called for a little more treated gallons at the higher mix for the "shock". I just did mine at the right mix at the 24 gallons my tank is. Run that until it's low and then fill it and run it like normal. There is also a "maintenance" ratio that you can run to prevent build-up as well. I didn't use that full tank in one day when I mixed the "shock" ratio tank of gas. It probably took me a month to use most of it and before I filled up again.

what to do after that? Run the gas out (depending on the wheather when you are done) winterize your boat and go for new spark plugs in the spring.

Run her once good in the spring and burn out all that fogging oil before you put in the new plugs...

I got a huge tank. I think 22-26 gallons. I think I have about 15 gallons in there now with a variable amount of seafoam. So what should I do now? Should I just fill the tank right up and dump in ring free for shock treatment now? And since it is going to take a long time to run through this tank, do I just take it out this weekend on the lake for fishing as per normal. In my experience, it takes about 3-4 weekends to run thru the whole tank. Also, does the motor run differently during shock treatment that I should avoid going into big water? Is it more likely to stall or require me to change plugs while I am out fishing? THanks

I have a Pro-v with very large tank. If I was going to shock my Merc I'd buy a six gallon tank to mix gas and what ever addetive, and use that tank instead of the built in one. This way you would know exactly what your mixture is. My .02
