Default 4 stroke produces more "thrust"????

In my own limited experience, I traded two 2-stoke Yamahas for two
4-stroke Suzukis and, thus far, they have proved much quieter, easier
to crank, and more fuel efficient (at the speeds I use). Plus, I
don't have to screw around with that crappy 2-stroke oil or have to
breathe its noxious fumes in an unfavorable wind.

Personally, I'll take the 4-strokes any day..... but then, they fit
my usage pattern.



Though the 1990s and up until this year, we had a series of Merc
two-cycle outboards, 90, 115, 135 Opti, on different boats. Since each
had a decent-sized oil bottle (the 90 and 115 under the hood, so to
speak), messing with the oil was not a real annoyance. The 90 seemed to
spew out more of an oil smell and smoke at trolling speeds than the 115,
but the Opti was a good-neighbor engine...no visible smoke, no smell.

Our Yamaha 225 four-stroke idles much more quietly than any of the
Mercs, and it is one smooth-running engine. I see where Yamaha has
bounced its 250 HDPI up to 300 horse. I'm sure in a few years Yamaha
will have a 300 hp four stroke and at that point, I'll trade in the 225,
for the 75 additional horses. Maybe.

So far, I have no complaints about teh 225 Yamaha.
