There is a lot more to it than just carb jets. For instance a kit to upgrade
a 9.9 to a 15 runs you about $800.00. That is according to my local Johnson
dealer.

I know nothing about these engines.

It is interesting that they weigh exactly the same, this tells me that
they may BE the same, much like some of the Evinrude/Johnson engines are
the same (9.9 and the 15, for an example) minor differences in carb
jets, and so forth.

I'd do some research and see if you could save some money with the 40
and get the performance of the 50 with the turn of a screw driver.

Anyone know?

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.
