My buddy just got a Stratos 285 with a 1995 150 faststrike. Are there any performance mods worth doing on this engine? He's the only Johnson in a club full of Mercs. The Guys in the club with 2.5L carb'd Mercs generally cut the heads, change the reeds and by-pass the advance module for manual advance. Never had a Johnson outboard so I am not sure if they like mods done to them.
