Yamaha 2 strokes were designed for a 2000-3000 hours.

Never seen it on a non commercial application. Those put on many hours in a few years due to running daily. I figured those outliers aren’t relevant to a pleasure boater that runs 50-200hr a year and never gets to 2000 before corrosion related failure modes become common.

Those old motors are the only 2 strokes you still see consistently.

Bulletproof.
They still sell them brand new over here but real simple……. Carbs not fuel injected, pre mix not oil injected. 🙂
Flat out all day, pushing commercial speedboats. They’re also less than half the price of a 300 4 stroke.

Yamaha pretty much owns the commercial 4 stroke market here but there are a few 300hp Verado (straight 6 version) powered boats. I’ve heard they run 3,000 plus hours hard use but more expensive to buy and service.

Yamahas also come with dogsh1t tiny props that are keeping some load off the LU and engine.

Never really thought of that. Those high hours are commercial use. I have 850 hrs on 2006 275's in salt and they still run like new. Couple rubber boots to replace and clamps but besides that nothing major. So just saying that corrosion and seals dont seem to be a big issue.

Thats old! I don’t see many 275s still kicking. I’d say you’re more of an exception than the rule.

Really? How old is "Old"? I was just paying attention to this at Peanut and the ICWW yesterday and thought there were a zillion merc 2 strokes. By "old" Im talking early 2000's stuff 2002-2007ish. I would assume most people went to 4 stroke but when I look, there are a ton of 250's old and new around here. Of course there are Suzukis and Yamaha but Merc still has the majority. Not talking triple and quad setups. Mostly single and twin fwiw...

I had a very low hour 2003 yamaha 9.9. I bought it used around 10 years ago. I didn't put many hours on it and used salt away every single time I got home. It rotted from the inside out. Looked like new from the outside. I think I posted pictures of it on this site. I'll see if I could dig them up.

I might be exaggerating, maybe I don’t notice them as much? Maybe a different market around here. St pete beach area doesn’t lack high end hardware. I see more smaller older boats over at beercan island for sure
