Johnson performance

[jasoncooperpcola]

I took my V20 out today for the first time since may. Engine is a 1985 Johnson 150, Top speed was exactly 30.0 mph at 4500 rpm with the engine trimmed all the way up. I ran a 6 gallon tank of gas/oil and a full can of seafoam till it got to low to run.

On that six gallon tank with about an inch of gas left in the bottom (maybe a gallon?) i got about 6 miles. I should get better mileage than that, right?

My only other concern was the top end rpm of 4500 rpm. I read on the prop that its a 15 1/2 x 14. It seams i have a "dead spot" in the throttle from after it engages in gear to about 9 1/2 o'clock. Is this normal?

Other than that she is very strong and ran good. No electrical problems with the motor.
