I've had a 2.5 Mercury 2 stroke for about 4 years now. It's pretty basic mechanicaly and has done a great job of pushing around my water tender 9.4, mixing the gas and oil is a little bit of a pain but the elimination of some service issues due to it being a 2 stroke is nice. It is also light and easy to carry around. When it come time to put it up I just run the fuel out of it and store it for the winter. Don't know how it would handle the salt but it does great in fresh water.
