Larry, I'd think tha even though the engines are rated for he
same hp,
there is a torque factor to be considered between a 2 and a 4 cycle
engine, though. two cycles have a 'power band' of RPM where they run
the best, where 4's seem to have a broader range e and more
torque on
a lower rpm. .

So, I'm wondering if the prop pitches between the two are really hat
compatable.

That's the question and I told him he needs a tach to determine that.
The 80's motors were rated at the prop and the new motors at the
shaft
(or vice versa), right?

If this is late 80s they were rated at the prop. The difference will
basically just be the torque curve. If he is not a WOT all the time
guy he will really like the 4 stroke.
It is really nice if you do a lot of close maneuvering at slow speeds.
You don't have that 2 stroke "cough, stall and a puff of blue smoke"
problem just at the time when you were going to make that perfect dock
approach.

LOL! I've seen that many a time. And have noticed on older engines in
need a bit of tuning, the power was never there when you needed it the
most. But plenty of sputtering for everybody!

After you get a 4 stroke you start being a snob. You see a an engine
belching along with that tell tale smelly oil smoke trail and say "2
stroke"

Most of my two stroke outboard experience was in the 1950s and early
1960s...and I simply don't recall any particular problems with any of
the engines. Back then, I thought the oily smoky trail smelled
like...like...VICTORY!

I had a two stroke Merc 90 and a 115 in the early 1990s, and they both
ran very well. Each of them blew stators, though. I never liked the
smell of the OptiMax oil in my late 1990s Merc, though.

Since then, I've had a couple of four stroke Yamahas. Two decades ago,
I wouldn't have said this: I'd never even consider buying *any* sort
of two stroke outboard these days. They are not competitive in any
important way with four stroke engines.

Stators are $700+ and you replaced two of them? That's some very bad luck!
