2 stroke / 4 stroke advice
My Honda 8HP had to be laid down a specific way.

I am a member of a Scuba diving club and we are
investigating replacing
our outboard engines.
We currently have two Zodiac 5m inflatable boats (not
RIBs) with 40HP 2
stroke Mariner outboards. These are reaching the end of
their lives and
we are looking at replacing them.
With the new legislation coming in we are looking at 2
stroke vs 4
stroke. I am aware that few people use 4 strokes on
inflatables and
fewer would manhandle them down beaches removing and
replacing them
daily as we do.
4 strokes are more efficient, reliable, quieter, and
cleaner than 2
strokes, but they are heavier. However, a newer 4 stroke
may be lighter
than an older 2 stroke. So look at specs when you shop.
I believe there are newer 2 strokes that meet
environmental
regs -- I don't know about in your size/power range
though.
Comparing specs is one thing, but consider what's
available to you
locally, parts and service wise. Everything's a
compromise.
Does anyone have any experience of using 4 strokes on
inflatable boats
in this way? Are there any implcations to the angle you
can carry/store
them?
The small Hondas I've used can be laid on their side
indefinitely. I
don't know about larger ones.
