[QUOTE="wmk0002, post: 458088, member: 13975"] I have a 1992 15hp Johnson that has been giving me fits lately due to some carb issues where the low speed mixture isn't dialing in well and the inlet needle seems to be sticking at times. I ordered a carb kit the other day and while waiting put on a freshly cleaned all metal 15hp carb off of my 1982 Evinrude. Took it out yesterday with my boat loaded out exactly the same as always and with calm conditions and was about 2-3 mph slower than with the factory carb and had slightly less holeshot. I was hoping that the performance would be identical. I know the motors have a couple slight differences but I thought the main stuff was exactly the same... like displacement and intake/exhaust manifolds. So I'm curious if anyone else has done the swap and if so how was performance different if any? Personally, I'd love to go away from the plastic top but not if it means sacrificing performance.
