Well were do I begin??

My old Yamaha (1988, 175hp, Model ETXG) *was a great motor for 4 years!! *The only thing I had to do to it was a new float switch for the oil injection tank on the motor.

I wanted to run it with a 50/1 mix, But Yamaha injection was set up so it never mixed with the gas, it went right into the cylinder.

Every time I went out I started to foul plugs when mixed in this fashion.

I was told that the carb jets were not set up to except this mix and thats why it foul??

I guess if you bought a Comercial Yamaha, they came with no injection and you could mix, it was your option.

Any how I was told from the guy I bought my motor from (He was a Yamaha rebuilder) That every spring I should run a tank of gas mixed 50:1

Yes I would get double the oil cause the injection would be working also. But it would not hurt a thing and will lube things well after the long winter.

This way you can check the oil injection to make sure that it was working. They sometimes stop working over the winter for many reasons? And you could ck *With out hurting the motor!!

Well this year I did not follow his advice, and I no longer have a motor!!

When looking at the injection system after I noticed that the internal linkage just pulled out of the housing. Its not supose to do that!!

Was this the cause of the cylinder failing?? Was it just 18 years in the salt water??

I have no idea, but one thing is for sure, what ever I get next will be 50:1 mix or I will never start runing with out doing the above!

I have other mishaps (not this motor) and tips, but I will wait for now!
