Johnson 225 fuel consumption

[Edwin CCK]

I've recently bought a 32

I've recently bought a 32 ft cuddy cabin boat with a pair of 1999 Johnson Ocean Pro outboards motor. Does anyone knows what are the fuel and 2T oil consumption rate on those motors and whats the best revs for fuel economy?

"Ed, The normal rule of thumb

"Ed, The normal rule of thumb is 10% of HP per hour (per motor) at WOT. In your case that would be 45 gal of fuel/hour at wide open. Figure about 1/2 of that for cruising at 32-3500 RPM. Oil is used at about a 60::1 ratio, so about 1 gal of oil for three hours cruising."
