1969 20' engine choice

[samuelcooper]

I am currently redoing a 69 SF 20 ft. (Will raise transom 5 in and deck 3 or so for tank and bailing). In looking ahead for engine choice I really like the e-tec. My choices would be 115 or 150. In reading old posts, the majority opinion seems to be 150 or more for hp. However, an e-tec dealer says the 115 will be plenty for the boat. So,...I'm wondering if anyone out there is actually running a 115 (e-tec or other) and can give info. on performance. I will rarely be on flat ocean so top speed is not that impt. But ability to plane and plow through rough ocean is. I took a 1977 Johnson off the boat and that was more power than I need.
