2 strokes ae readily available in models that are a couple years old.
These may be a good deal if still under warranty.
Considering the hassles of how a 4 stroke cannot be tilted some ways,
how reliable are they compared to a 2 stroke?
How expensive to repair compared to a 2 stroke?
Considering a cost differential of about $1000 (US), is fuel economy a
real consideration for a 4 stroke?
Everything that I've seen, heard, and experienced points towards the
4-strokes. The newest two-strokes aren't as bad as the old, but they're
as complex as the 4-strokes and seem to need more maintenance.
A couple of years ago, a rental or charter operation in the Keys
detailed the benefits over the long term in his fleet of small boats in
this newsgroup. One of the unusual benefits I recall was that the
4-strokes lasted at least twice as long -- same boats, same use.
Two strokes have a lot of benefits, but if two stroke technology were
truly as clean and efficient as four strokes, I would expect to see
automobiles switch over, particularly the smallest econoboxes.
The only sorta two-stroke I can think of is the Mazda RX-8 rotary. Now,
THAT's an engine that gives outstanding power to weight! Are there any
rotary outboards?
