Seafari 20 Power

[NorthBay]

Hey Folks,

I am new to the site having just bought a 78 Seafari. She needs a lot of cosmetics but is solid as a rock! The boat came with an 1985 Evinrude 150 and my intention has been to run it till I can put away some cash for an upgrade. No idea of the hours on it but it looks pretty clean. However, I checked compression and got a bit of a dissapointment. Port - 100, 95, 95 Starboard 80, 85, 80. Carbs need rebuilt. Trim/tilt is bad too. It sat for 3 years. I have a yamaha 115 four stroke at my work I could buy fairly cheap but it needs some work...lower unit and maybe few minor things as well. I have had tilt/trim trouble with it over the years too. Yamaha has 1400 hard hours of summer camp skiing and tubing. Where would you guys put the money and effort? Is the yamaha a good match for the boat? Your thoughts are appreciated!
