The fifteen probably has about five horsepower you can't use. I used to sail a Grampian 26 on Lake Michigan with a mid-eighties Evinrude 9.9. It was sufficient and could run for hours on end into steep, tall Lake Michigan waves. A 9.9 should take your boat up to it's hull speed with no problem and cruise very nicely at around 70% throttle. The fifteen will probably just burn more fuel.
Yes, $360.00 would be a good price for a fifteen in good condition. BUT...the one you're looking at appears to be a short shaft. Even with your retractable motor mount, I suspect you'd find yourself spinning your prop in the air a lot more than you'd like.
I'd be looking for a long shaft 9.9.
Having run two stroke outboards for years, I'll throw in a couple more pieces of advice...forgive me if you already know:
1) Always use the best two stroke oil. Johnson/Evinrude or Merc's Quicksilver. Grab a can of Quaker State two stroke oil, or start messing around with other brands and you will regret it (fouling).
2) Always use fresh fuel, and be sure to use stabilizer in it at the end of the season. Be sure to add stabilizer to your fuel and run the engine long enough for the stabilizer to go throughout your fuel system (into the carb), so you're not gummed up in the Spring. Old fuel is okay in a lawn mower, but will cause poor running or lack of running with an outboard. Use an engine fogger at the end of the season.
If the engines good and you have good plugs in it, and you follow rules one and two, an eighties Evinrude will reward and amaze you with its reliability.
By the way, I'm still using the Evinrude 3 horse that I got when I was five. I follow rules 1 and 2 to keep it reliable and I'm 53 now.
