shen, the "down" component is indeed quite noticeable. In fact, it is
the
reason outboard runababouts have the steering wheel on the right side of
the
boat.

"THE" reason? No.
If it was THE reason and the boat needed that offset weight to counter the
"down" component, imagine what might happen when you put the engine in
reverse.
Is it a possible reason, among a number of reasons - yes - the particular
application will dictate it's degree of importance, if any.

Do they put the helm on the other side if the prop turns the other way?

They put the helm on the right hand side because the traffic
approaching you from that direction has the right of way, and
it's important that you be able to keep an eye on it.

Jeeze.

I was hoping it was obvious that it was a fecetious question. Guess
not.

Sheesh, yer spellin's worse that mine.
I'd say the other Steve's "Jeeze" noted the seriousness of the question and
his response.

nah. outboards have had rh turning props since
loooooooooooooooooooooooooooong
before the Rules of the Road (originally an east coast yacht club's racing
rules). Ole Evinrude's engines (built in Milwaukee and sold to and for
Midwestern fishermen operating on Midwestern lakes a three or four day train
ride from the east coast) turned clockwise (from the top) because most men
are
right handed (and this made it easier to hand start the engine turning cw)
and
a cw turning engine could have a cheaper, longer-lived thrust bearing in the
lower unit if the prop turned right, thus lifting the right side of the boat
from the reaction to the torque of the prop. Therefore, the boat operator
sat
on the right side of the boat. Still true to this day for outboards.

Nah, had nothing to do with the with the torque and lifting the boat. Them
things had just enough torque/ power to push the boat forward. Was all about
starting and the thrust bearing.
Waddahey Jax, for you, two outa three's a miracle.

YES, our 1954 Feathercraft with the 30/33hp Scott, and later 40hp
McCulloch, had the steering on the left from the factory. When we
switched to a 50hp Johnson in 1975, the steering & all controls were
moved to the right. Our 5hp Scott was a LH prop job too...

Hmmm, maybe it was a serious question afterall. lol
