When I went down from 75 to 60 my top speed changed about 1-2 MPH.

That's interesting. I thought the opposite because of the nature of
the two hulls.
Unless that 1-2
Mph represents a large percentage of total speed.

I went from 23-25 to 22-24 (depending on the load).

Get a spec. sheet and read it. If everything's the same, why not have
10 more HP?

Interesting. A 20% drop in horsepower resulted in, for all practical
purposes, the same speed. I assume that the props were similar in
size and pitch?

Just out of curiosity, which was more efficient in terms of GPH?

I called my dealer and asked what it would take to upgrade from the
Honda 40 to the 50. He said "don't waste your money, they're basically
the same engine." He also said you don't gain much moving up in
horsepower with pontoons, which I've heard before. He was very
insistant that the 40hp was the best motor for my "smaller" pontoon. I
don't believe everything this guy says. The 40 I agreed to is a 2003
so I'm wondering if he just wants to move it. It's a huge store so I'm
sure he has 2003 50's too. Honda told me that the 2003's and 2004's
are IDENTICAL so I thought I'd save a couple hundred bucks.

Should I stick with the 40 or push for the 50?

IF your pontoon does not plane then 10 HP more or less might not make
a difference. On a planing hull I would go with more rather than less
HP.

The motor is basically the same engine. The 40 is just not tuned as
much.

I also wouldnt believe too much dealers say ... And it is likely he
wants to sell this motor ....

You need to revisit the pontoon thing.... ask pontooners if 20% HP
make a difference. Chances are if you operate in low wind and it
doesnt plane anyways there will not be much difference.

However if you would save $300 then get the bigger motor to start with
as it will run at lower RPM and probably use less fuel at cruise.

look here how different motors/HP performs on different boats:

its yamaha but in relation it will be the same

When operating non planning vessels you can throw outragous amounts of
HP at them with little effect in speed

No comparison in fuel consumption, the 60 EFI is a lot better, particularly at
slower speeds. You really don't buy a 4 stroke if you want to go fast (WOT) and
at 3000-3400 16-17MPH the 60 is a lot better on gas.
