You can still buy two stroke outboards, the evinrude ETEC.
Any other two stroke outboard you can keep, they were all pieces of crap. The newer 4 strokes are 100X more reliable.
It never ceases to amaze me the amount of nostalgia there is for junk.
2 stroke yamaha 15, Circa 83 IIRC, still running, never had anything but a carb kit. Probably beat up 10 props already. Still runs just fine. We used to put hours on that thing, they we slowed up and a buddy needed one so its on loan to him. He fishes the river at his house sometimes at least 1-2 times a week...
Brand new yamaha 4 stroke 25.. dunno, maybe 2002 ish... ran fine at first, and then had to have carb cleaned between EVERY run.. morning/evening etc... found out though not the motor, the ethanol was eating up the fuel tank plastic.. so I put on about 200 bucks of new everything that would touch the damn ethanol.....
but I'm a bit OT... LOL
