Few questions about a 1991 115 TXRP

[captb]

First, what would an average fuel burn be? I'm gathering these aren't the most fuel efficient motors, but so far I'm decently pleased with a motor of this age. This motor is on an 18 ft. Wellcraft, and I fully understand that each motor will perform differently on individual boats, just looking for a ballpark.

Also, it mixes oil itself, from a reservoir- well, there's two, one on the side of the motor and a larger remote. Do these motors start pulling oil from the remote after the oil is pulled out of the one on the motor? On that subject, what's the mixture ratio?

Thanks for the help, B

100-1 and yes it uses the remote 1swt then goes to one on motor...when oil starts to get low on motor will sound horn

100:1?! Really?
Its definitely mixing a lot thicker than that then, the motor smokes like a freight train at idle. I had a Yamaha Enduro motor on my skiff several years back and it was 100:1 and it ran terrible if you mixed it much thicker than that.

Thanks, B

Yam 115 is 100 to 1 at idle and then goes to 50 to 1 at WOT
