Brett,
Find yourself a good, used,
6 hp Johnson/Evinrude or Merc
2-Stroke SHORT SHAFT, almost any of them made in the past 20 years, that LOOKS to be in really good shape (make sure the owner starts it up and runs it for you:idea: Look inside the Motor Cover and make sure you don't see signs of lots of rust/corrosion).
There's kind of a trade-off between weight and power on these things.
Unless you get one of the really lightweight 2-3 h.p. jobs that doesn't have a Neutral or Reverse, the 3.5-4 hp water-cooled models are HEAVY for what you get, powerwise.
Once you get up above "6 hp", you're really getting a 10 hp motor (that weighs more) that just doesn't make 10 hp! (When you look at various year's motors, you'll often notice that the 6.5 hp and the 8 hp or the 8 hp and 10 hp look the SAME!:shocked: They ARE! Just you'll notice that the new price is more $$ for more hp and the one makes more hp at 1,000 rpm more

assout: It may have a larger carb and the timing advance is set to go 1,000 rpm higher, that's ALL:jester

.
Also, consider if the motor is fed by an onboard tank (like the little ones) or a seperate gas can. Don't forget the seperate gas can is an extra piece/extra weight, but also gives you the option of a small tank (3 gal.) or larger (6 gal.) IF you need to go somewhere "farther":applause:.
Using a 6 hp motor, a 3 gal tank should get you ANYWHERE and back on S.I. WMA:wink:
4 Stroke motors are what are currently manufactured, but remember, they're HEAVIER! (There's all that "stuff" going round and round and up and down IN the Head, where on a 2-Stroke the Head's just a simple cap that holds the Spark Plug)
Oh, and on the Trolling Motor, while they're nice during warm weather, they're less efficient in the cold, the Battery is HEAVY, and don't forget all that gear clunking around, they can get tipped over, and are full of ACID, just one more thing to have to worry about!

assout:
:cheers:
