Question
I have 70,s & 80,s outboards and have seen extensive engine damage that I was told caused by ethinol. What do you think. What can we do when all oil co,s go to it?
You should not have extensive damage from ethanol unless it is in greater concentrations than 10%, actually would need a lot more to cause damage.
The damage is usually confined to rubber items like carb kits and hoses, fuel pumps, etc. The engine and aftermarket manufacturers have already produced alcohol resistant parts. Most are of a brown or tan color.
Some items like the VRO in OMC products can be identified by the brown nipple on the VRO.
It will be a fact of life so we will just have to deal with it. We shouldn't have any major problems as long as we maintain the engines properly.
