I think that the new generation larger 2 strokes (100hp+) might be the way
to go in the future.

I like 4 strokes around 100hp and under. They are queit and do get great
fuel economy.

Have you looked at the Evinrude Etec?

Many are Yamaha (2 or 4 stroke) fans though for dependability.

In my experience, the 2 strokes are stronger accelerating - better for
pulling skiers. 115 hp is 115 hp no matter how many strokes, so top end
should be close. Usually, but not always, the r stroke is easier on fuel,
but it depends on how you use your boat. Personally, for my application,
I am having a hard time choosing between a 150 hp Optimax or a 150 Yamaha
4 stroke. The Opti is hell for strong on the low end, but the Yamaha is
awesome on gas and at the top end.

If I switch from a 115hp 2 stoke to a 115hp 4 stroke, where will I
feel the difference in performance? Top end? Load carrying capacity?
Both? Other?

I'm considering a 115hp Johnson 2 stroke (carbs) vs a 115hp Yamaha 4
stroke. Yamaha doesn't offer a 25" shaft on its 115hp 2 stroke or I'd
consider that too.

I've run a 115hp Mercury 2 stroke on my boat and it performed well. I
don't like the 2+2 design Merc though soooooo.... decision time.

I mostly carry two people but if I carry four, that's an additional
400 lbs give or take, and I don't want to lose much zip. My 115hp 2
stroke handled if ok but..... 4 stroke? -I dunno- I don't really
care about top end as long as I can keep it over about 30-32 mph.
With two people, 35mph is do-able with my 2 stroke and I would't lose
much speed adding two more people.

Anyhow, my only experience with 4 stroke is my Honda 20hp on a skiff
and it just doesn't seem to have the load carrying capacity of a 20 hp
2 stroke. Frankly, I doubt it can keep up on top end with a 20hp 2
stroke either.

Anyhow, any opinions appreciated.

TIA,
