Question Replacement Engine Question

Well I am looking for a new-to-me engine and I keep finding some Johnson 115HP 20" shafters.

My question is, what would be the performance differences from my Evinrude 150HP?

Would it just be quiter and better on gas?
Would I just not be able to move the V at close to 45 MPH?

Any comments would be greatly appreciated.

What year 115? If it is a 95+ that is a V-4 60 degree looper then it will perform pretty well and be a rock solid engine. The earlier 115's that are the cross-flow engines are still good engines, but not quite as powerful and definately thirstier.

Shoot, if a 115HP will move a V-20 at 45 mph, then I need to trade in my 200.

So a later model 115 would be a good fit for a V?

I am just looking for something dependable that will plane the V and cruise at a decent speed, say 25 - 35 MPH.


By the way, I never hit 45, the first year I owned the V I was hitting 40 and then each year
I noticed a reduction in top speed, I should have known then that I was losing compression.
