One more reason to not trust a VRO
 

Found this one on another site, the VRO fuel pump quit pumping so the owner kept pumping the primer bulb to keep fuel to it to get home. Well when you pump the primer bulb you get gas ONLY, no oil. And then this can eventually happen.

Ouch!!!

Gulp.

But is that the fault of the VRO or the owner??

looks like a nice melted 60 degree there. i think the moral of the story here is just because it work doesnt mean you should do it. (pumping the bulb)

Well the initial failure was the VRO pump, but the owner took it to another level with trying to limp in. And yep, they said on the outside it was a nice 2000 150 JOHNSON, pulled the heads and found this throughout.

holy crap thats gonna cost

Found another VRO victim picture to strike fear. Looks like it did some damage too, same cylinder as the other one.

Very
Risky
Operation

FERM, your makin me nervous.......stop

Yeah I know, I have a boat that is still oil injected. I actually removed it from my MERCURY on my flats boat, when I put it up for sale everybody kept complaining about it being removed. So I put it back on for a guy because he said he would buy it if I did. Well I still have it, and will be removeing it yet again if it doesn't sell soon.

Did he say whether his alarm went off? If not, I can somewhat understand why he tried limping in.

Also, if he had to pump the ball to get in then wouldn't some of his damage be probably already done? It doesn't seem to me that lack of oil would keep it from running for a bit.....until something gets FRIED.

Wow, sucks majorly for that guy.

i doubt that guy was running a VRO. he has studs on the heads (highly modded engine). probably running alot of timing. and it looks like a really really old crossflow. i think the blocks that were painted blue were in the 70's era before variable ratio oiling.

I suspect not a VRO issue as well. VRO mixes oil with fuel prior to the carbs. if the VRO wasn't functioning correctly that lower clyinder won't look as good as it does compared to the top. Understand the top gets hotter quicker than lower clyinders but that's just too much of a difference for me to believe VRO was the only problem this engine had!

Not my picture, just re-posting. He claimed it was a VRO mis-hap, who knows though. Although I do have a YAMAHA 250 that lost just one cylinder like this and it was an oil problem, the other 5 looked fine.

My Yamaha also was a oil issue!!

Middle cylinder on one side got messed up, but none of the other 5. But I did not run mine past idle, I heard the noise and was not to far from the ramp, jut shifted in gear and got in it, the damage is nothing like pic above but none the less it was 1 cylinder out of 6 and the oil pump was in 2 pieces when I found it.
