1986 150 yamaha fuel consumption?

[topdogeye]

Just got another toy with an older yamaha 150 not exactly sure how much fuel I'll be using on any given day on the water. Anyone out there with an older yamaha that does a good bit of running? I'm thinking of covering say from 20 to 60 miles possibly on any given trip out.

The motor is pushing a 20' McKee just to give yall an idea. As of now I have a 24 gallon tank set up can add an aditional tank if needed.

Look here for what fuel consumption at different RPMs of boat/motor similar to yours. Rule of thumb is 10% of the hp at WOT per hour, but not many run WOT.
