The motor is a "force" made by Mercury. It IS NOT a Force or even a Chrysler Force. Both of which are really bad. It's a tank of a motor, but pretty indestructible. It isn't gonna be a fast boat. But, hey....it was cheap. I have a Nitro with the same motor. The motor is solid. Has probably 1000's of hours on it. Replaced the starter twice and plugs once. Change lower oil yearly. That's it.....oh...and a repaint.
Looks like a great starter boat. Tell him to see if he likes bass fishing. If he does, it will make a good trade in on a new-er boat down the road.
RIP little Nitro
