Clint, When you say "Pontoon Boat", do you mean the ones with Aluminum Pontoons (Logs) or a split V fiberglass job ? If it's the Aluminum kind, I've had 4, in the past 20 years.
The 2 most recent were..
A 24 foot Party Barge with a 115 hp Merc (POS). It would pass everything but the Marina gas pump, would pull anything.. multiple skiers, tubes.. even an 8 person Serpent looking thing. Couldn't troll with it more than an hour.. cuz it would Load Up'n crap out. Not good for Fishing. Sold it.
In 03 I skinnied down to a 20 foot G3 Fisher.. has a 75 hp 4 stroke Yamaha.. GREAT motor, quiet... I halfta look at the Tach or water.. to see if its running while trolling. VERY economical too. Will pull 2 skiers, Tubes but not Yahoo fast, maybe 30 MPH.
The "Beach Ladies" don't wave at me anymore.. cuz it aint Big & Cool, but theze dayz, I'm more concerned about the number and size of the Fish.. I have in the Live well it has onboard.
JMO but get at least Half, At or Near, the Max HP, for the length & wieght that is recommended by the Maker. And get a GOOD 2 axle trailor.. not the POS thing that usually comes with those "Packages". The trailor needs to be stonger than the boat. If not ? the boat Flex's with the trailor.. Not Good.. in time.

condensed, that would be..
"get one big enough for a bunch of diesel gearheads to come over and do some serious drinki.. er, I mean FISHING!
