Do dealer test drives damage new engines?
I recently tested 3 new boats from 3 dealers. In each case, the boats were new and never in the water, so 0 hours. Each dealer immediately ran the boats full throttle at max RPM's within 10 minutes of testing the boats. This goes against all the manufacturers suggested break-in procedures, right? I bet most dealers do this and I wonder how many engines are damaged as a result, though I've read the newer engines require less break-in period. Still, max RPM on a fresh engine, yikes!!!

Then run em all at WOT for their lake test at the factory anyway. Don't think there is any getting around that.

2 schools of thought:
-break in slowly at varying rpm's for a predetermined amount of time/miles.
-let the rings land hard and break the engine in as you will actually use it.
I was a proponent of the first for many new vehicle/boat/motorcycle purchases until i watched a show on discovery about the honda and kawasaki factories in japan turning out sportbikes. both companies, once the bike is assembled, roll to a dyno and run them for minutes at varying rpm's including a full throttle run for north of a minute to get a final dyno reading and ensure they are at the advertised HP ratings. my zx6 had a 16,500rpm redline so it's not lumbering some engine along. amazingly enough after taking delivery the manual states some crazy long break in. after seeing this, I have not followed break in on 2 sportbikes, 1 sports car, a sedan and a boat- all purchased new- with nary a problem and none had any oil usage.
my only advice is do what you feel is right for you.'06 Supra Launch 20SSV-gone but never forgotten

They don't make you break in cars or trucks , so I think these engines are fine

An engine is an engine... I build them all the time. I don't break them in. If it's got oil pressure, Run it. It's more important to get an oil change in quickly (first 500miles or equivalent hours for an airplane/boat) than a break in. These are full roller motors as far I know, so there's no seating in lifters on cams, push rods on rockers and all that fun old school stuff.

After roadracing motorcycles and watching winners literally pop the tire by burning it down. I dont think you can hurt most motors.
I have heard them banging the rev limiter for over 2 minutes (until the tire pops) with no issues. In fact to win the next weekend on the same motor.

No! These engine can be driven in a manor that they are intended, right from the start. Break-in is a 99% CYA.

I think, if you have never owned an inboard before, just cruising around a different RPMs for 10 hours is a great idea so you learn to drive your boat. As for the engine-- LOL!
