Rapman - I Have been running a 115 four stroke Merc. on a blazer 100 gauge aluminum hull with a 5 degree V, It does great on lakes and gets 5 miles per gallon on gas. I have used it at Tany, Lake of the woods in Canada (big waves there), Bullshoals, Meramac and Gasconade. I'm extreamly happy with it on longer lake runs over a flat bottom boat and it does well in skinny water also. I saw one at AArons in Rolla that was really reasonable last week. Worth a look.
