It looks like theses motors use the same block, likely intake and
exhaust. HP difference may come from carb and rpm.

Weight of these motors is pretty much the same. Often the more
powerful motor will use less fuel at certain speeds as it doesnt have
to work as hard.

The only issue that would point at the 40 HP is money. If cost for the
50 isnt prohibitive then get that. I wouldnt recommend getting the 40
and lateron tweak it to get 50 HP (not worth it).

I dont know how well tubing with a pontoon boat works ... might
require twin 400HP ?

I'm buying an 18' pontoon that weighs 1050 lbs. I decided on the 40hp
Honda but I'm wondering if the 50hp would be better for pulling my
kids on a tube. Besides tubing, I'll also be trolling for walleyes,
trout, etc. Both motors weigh 212 lbs.

Any recommendations? I need to decide soon.
