20' SeaCraft re-power

[Reelsknotty]

This past week was awesome. I scored a good deal on a Suzuki DF150, got it shipped to me and installed all within a week on my 1986 20' SeaCraft. The previous motor was a 225 Mercury Optimax. I was originally looking for a new (inline 4) F200, but there aren't any used for sale and a new one just didn't make sense for the amount of money they are vs. the boat it was going on. Once I gave up on the F200, I quickly stumbled across a brand new 2012 DF150 from Central Marine in St. Petersberg. It has been on the showroom since 2012 and came with 6 years warranty! The initial performance results are as follows:

Running 3x15x21 Solas Prop
Motor mounted all the way down
1 person and 64 gallons of gas

3500 RPM 22 MPH
4000 RPM 27 MPH
4500 RPM 33 MPH
5000 RPM 38 MPH
5700 RPM 43-45 MPH

I'm pumped about how quiet this motor is. I still have to make some adjustments. The throttle is too jumpy to me, but maybe that is the Suzuki controls. The motor will also be coming up 1-2 holes. From there I will start working on some other props.
