Our 2003 Yamaha 225 four cycle calls for a 10-hour break in. The
dealership has a back-right-down into it freshwater tank, so the engine
spent the first hour of its operating life on the boat on the trailer in
that tank, running at the specified throttle settings and being checked
over carefully by the mechanic.

So, the answer to your query is, yes, you can certainly partially break
in your new engines in the tank.

Hey Hairball, do you have a furrin motor????????
