adding isopropyl alcohol to a 2 stroke.

Does it cause any problems in trying to get rid of water to a yamaha 250 efi late model ?

I wouldn't use isopropyl. I would use HEET or other acetone type additive.

Any kind of alcohol is bad for rubber fuel lines and hoses. Don't do it.

This is absurd.<br /><br />Isopropyl in small amounts is just fine. In amounts where it is used in higher than the recommended amount, it can create problems including a lean condition on a 2 stroke. <br /><br />High isopropyl mixtures will lean a 2 stroke equivilent to one jet level and if the amount get high enough, it can also cause some oil washing on the cylinder walls.<br /><br />In the northern climates, isopropyl is used in 2 strokes all of the time especially in snowmobile engines. Much of the gas is an ethanol blend but for areas where that is not available, isopropyl is used regularly. Again, in many snowmobile engines it is a necessity. <br /><br />Now methanol is a whole other matter...obviously do not use that in a 2 stroke...<br /><br />Use common sense, use isopropyl conservatively, and you will get rid of the moisture with no problems.

With any outboard you should run decent quality water separating filter like a Racor between the tank and the engine.This will ellininate any chance of water getting to the engine from the fuel.If you have water in your system and don't have a w/s fiter ,draining the engine of fuel and installing one will fix the problem.

Also, beware of isopropyl rubbing alcohol sold in pharmacies. It generally is about 60% isopropyl alcohol and 40% water.

Thanks for the detailed info......it sounds like it falls in the catagory of the pills I take.

The 70% variety is 30% water, and the 90% is 10% water. So just how in heck can that get rid of water, is beyond me.<br /> I've done many an experiment, and find a $10 bottle (which treats 90 gallons if I remember correctly) of WaterZorb the best. Any boat store

Problem with alcohol or alcohol based water eliminators, is that they will attract the water and form a gooey jell. Had 2 instances of this:<br /><br />1. Had a 125 Johnny die at full rpm's one day and after half hour or so of troubleshooting, found this goo blob at the entrance connector to the engine. No more anti water stuff and no more goo blobs.<br /><br />2. In the summer I used to dilute my windshield washer fluid in my truck with water. One day my washer quit working. Pulled out the strainer (on the outlet hose) and it was choked off with goo. Drained it all out and cleaned things up. No more water dilution and haven't had a problem sense in many many years.<br /><br />I like the idea of the water separating filter. I think the fuel molecules are much smaller than water molecules so the filter has a real fine mesh on it that allows the fuel to pass thru but blocks the water.<br /><br />HTH,<br /><br />Mark<br />[<br />HTH<br /><br />Mark

DO NOT USE ALCOHOL<br /> not in a two stroke<br /> it tends to mess with the lubrication<br /> best to drain the system and manually flush the water.<br /> I see it all the time and it blows many a good piston.<br /> problem is it will emulsify the water only to later plug the VST filters and the filter inside the injector and lean the fuel mix and detonate a piston.<br /> in carbed motors it tends to coagulate the fuel in the bowl and do the same thing.<br /> believe it or not.

Many gasoline blends are already 10% ethanol. Engine makers and automotive OEMs usually state in the owners manuals that 10% is max; more can corrode fuel system components and/or react with synthetic lines, hoses, etc.<br /><br />Methanol is worse - more than a few % can cause trouble.<br /><br />If concerned about water in gas then use a separator as recommended already. I would NOT add any alcohol to fuel on an EFI engine.
