Well we went out an bought our 1st boat. *It's a ski/sport boat. *It's a 1991 with a 91 120hp motor on it. *The motor needs to be run pre-mix 50:1. *I was wondering if anyone runs their snowmobile oil as a pre-mix? *I run Klotz and plan to run it in the boat because I want to go synthetic. *Is this a good idea or not???

Thx

Some people may disagree but it think that snowmobile oil and outboard oil is the same thing.

I would use it but i would get a second opinion before you take my word.

All the time.

I belive that there is little difference in the oils. *Wasn't many years ago, and you just bought 2 stroke oil. *I think the sled oils have a lower poor point, and some are lower smoke, but it won't make a difference in the boat.

I burn amsoil in all my 2 stroke engines.

If anything the oil for sleds is of higher quality than outboard oil because of the extreme temps it is used in. Just make sure the oil you end up using meets or exceeds the manufacturers recommendation...(TC-W3?) which a quality oil like Klotz surely will.

I run Polaris blue in my oil injection on my 150 Johnson Fastrike. It was recomended by my Polaris tech training instructor to stay away from the higher end premium oils.I wish I could remember the reason why but that was a couple years ago so shoot me.I know for one thing *do not use injector oil in a premix situation because when the boat sits for a period of time the oil will seperate and settle to the bottom of the tank and when you start it it will suck nothing but oil and cause all sorts of problems. I learned this the hard way when I had to tear down the carb on my smaller boat out in the middle of Lake Of the Woods, The carb was full of oil and no Gas just straight oil and they do not run very well on straight oil. http://www.snowmobileworld-s2.com/forums/iB_html/non-cgi/emoticons/mad.gif

I believe Klotz carries the NMMA ? rating which I think is what the marine industry uses, e-mail Klotz I have found them to be very helpfull, and by the way I run Klotz in all my 2-stroke stuff chainsaw, weedwacker ect.

As long as it is TC-W3 (which is probably recommended in the manual for it) it should not harm it. The only differences I found from Amsoil and the recommended name-brand oil was the price!

My 150 Evinrude Intruder on my Ranger got nothing but Johnson/Evinrude 50:1 oil the first few years, but the last couple of years I have been running the Pennzoil 50:1 TCW3 which you can get from Walmart for less than $10 a gallon. *The main difference is the amount of oil the outboard goes thru versus my snowmobiles. *That V-6 sucks ungodly amounts of fuel/oil. *I guess I felt if the pennzoil is good enough for Orlando Wilson then it's good enough for me. *At the beginning of every season I run a can of decarb (OMC Engine Tuner)thru it which helps clean the combustion chamber and desolves carbon build up. *Most of the good after market oils meet or exceed OEM oils and do not void any warranties. *I haven't noticed any performance drops or any problems, just more money left in my wallet.
