How much oil is used per tank?
 

1987 V20 fish (cuddy) with 1996 V6 Johnson Oceanpro 150. Just replaced VRO pump on this new to me boat and was just wondering what kind of distance/hours does 2 stroke oil generally last? First time out in boat with family, I burned 45 gallons of fuel (took a trip around Staten Island and visited Statue of Liberty). I put the boat, I feel, through it's paces. and after I fueled up, I forgot to check the VRO tank. I know I physically put in 1 gallon before trip at first fillup. Just wondering if I should refill before using again. Thanks. (no pics yet)

you should be close between 40-1 and 50-1. so for every gallon of tcw-3 you put in the tank you should burn around 40-50 gallons of fuel.

And ALWAYS fill up your oil tank every time you get fuel. This is just a safety precaution as you never know if the low oil alarm will sound or not.

You sould also keep an extra gallon on the boat as a back up.

Bingo!!...great suggestion...I wouldn't leave the dock w/out lookin' at that oil tank

The best thing you could have done and saved money was to never replaced the pump and mixed gas from now on!
O well good luck!

It's a 96, I think they got the bad pump issues taken care of by now. I'm sure the new pump is a current manufactured one. If you slow troll enough, you'll foul the plugs with premix. Maybe I was one of the fortunate few, but when I ran 2 strokes, I never had a pump related problem. There are a bunch of flats and bass boats still running two strokes (due to 4 stroke weight) with no problems with newer design oil pumps. Just my $.02.

i need to post pics of the vro pump i have apart here at the shop.

I had a 1985 Evinrude 90 h.p. with VRO and never had a problem with it. Perhaps I was just lucky. I loved not having to do the premix thing.

Wish I had known that before the $600.00 repair, plus the time down. The pump was also replaced by the previous owner in 1994. It seems odd that it wouldn't last that long. Don't worry, if it ever craps out again, out it goes and I'll go to mixing myself. Thanks for the replies. I tried to figure out in my head at 50:1 ratio, giving me a full 60 gallons plus before refilling, but being the anal annie that I am, it will be filled again before the motor gets turned on again. And I do carry a spare quart under the port seat, just in case. Thanks again.
