I was wondering any opinions on two things. How does this gas consumption sound -- 20 minutes (no wake) each way in and out of channel, 3 hrs nonstop tubing with 5 kids 2 adults, food, drinks, ( got 5400 RPM's ) gear put in 11 gallons before trip 89 octane. Fuel gauges were right back where I started when I was done. Now my other question, I have been hearing a chattering at 3000 RPM and above, had engine cover off and I put my head right next to block and i didn't hear it, sounds like it is coming from the lower unit. It is driving me nuts. I have VRO, lines are only two seasons old. I topped off my oil tank at the beginning of the season, it has hardly moved, I have put approx. 8-10 hrs. on engine. Can the noise be that the engine isn't getting enough oil at higher RPM's. I would think if wired up right there would be an alarm or it would'nt allow higher rpm's? I am afraid I might be further damaging something. Any thoughts

I figure that according to this calculator, at 50:1 mixture, you should have used 28 ounces of oil..
http://www.csgnetwork.com/oilfuelcalc.html This is why most of the guys here hate the VRO and disconnect it and add oil directly to the tank with the gas at fillups.

I still use mine, only because I just recently changed the pump and it is new. Try posting this as a question in the forums. A lot of guys here have successfully done that and can guide you through it.

http://www.westmarine.com/webapp/wcs...x#.UAMteZEw8TA Many places have these other than West...Walmart has 'em I think...no matter where you get it, it has graduated markings on the side to determine the amount of oil you need to add...A NO BRAINER which is the way I like it...on mine, it indicates one full bottle to 10 gals of gas...for instance 25 gals gas would get 2 1/2 bottles of oil...and so on...it's a perfect measure every time... My rule on auto-oilers: If it ain't under warranty, disconnect it...but that's just me...lotta people love 'em and use 'em...
