letter on ethanol

[slapshot]

We have had the ethanol crap in our fuel in CT for a couple of years now. It flat out sucks in outboard applications. Alot of the Yamaha guys (myself included) have had problems. On the high pressure fuel injected boats, it is clogging a filter located on the fuel rail.

It breaks down the primer bulbs, o-rings and some fuel lines. I had to replace my primer bulb, and fuel lines. It clogs the crap out of carburetors. The ethanol basically causes any crud on the inside of your fuel tank to scrub clean and suspend itself in the fuel mix. This clogs everything. Also ethanol attracts water.

If you don't already have a Racor or similair with the bowl that you can see water and when to drain it out of your fuel system - get it. Also get the finest micron size filter you can find.

I wound up having to learn to rebuild my own cars. My boat sat at a Yamaha techs facility for six weeks! Then he tried to charge me for storage when I told him I'd fix it myself.

Slapshot - I'm new to the new boat/motor world last year. I'm running a Yamaha 4 stroke 150. I spoke to their rep regarding Ethanol and they stated that these engines would be fine with up to 10% which is my understanding for Mass.

When you state you had all sorts of issues, is this for all Yamaha engines? Any advice besides what was already posted? Txs.
