How to properly break-in your Mercury V-8 outboard.

I recently took my new Nitro Z-21 out on the lake for the first time to get the break-in process started on my Mercury 250 Pro XS. Doing this right will serve you well in the long run. It is extremely important for the life of the engine to follow the directions well. It’s not a hard process, just takes a little time. Hope it helps you out!
