Re: Need help getting started - No oil seized two pistons on Evinrude 175 V6 two-stro
If someone has used ether starting fluid on those plastic carb bodies, it can "craze the plastic" in the throats, and it effectively disrupts the smooth airflow and venturi effect that the carb uses to suck gas up from the bowls. The cyl runs lean.
I blew my first engine (200 looper) by using ether.
Heck, I just wanted to see if it would fire up for a second or so. It didn't, and the wet ether stayed on the carb throat. It crazed.
So, two years later, after a 12 hour run, I had what you have on your #1 piston. The whole block was full of aluminum.
Rub you finger over it, and you ended up looking like the tin man.
But, no, if you ran it with no oil, then no, that is probably not the cause.
And, many will tell you, the VRO cannot cause this failure. If the VRO quits oiling, ALL cyls will be affected, not just two.
Which brings up the question....why ONLY TWO failed when you had no oil in the gas?
Something is not adding up. You say you had no oil in the gas, but the internal engine surfaces are all oily....
Go back and re-think what has happened.
Take a sample of the gas....it should be colored blue if it has oil in it, amber if not.
