!!! Boat Purchase Update !!!

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?
