Spent the day working on restoring my 08 Speedster 150 - 155HP NA model. Got all the old graphics off, detailed the engine bay, etc. I ran the boat several times today, out of the water, no hose. Never more than a minute, I would guess 30-40 seconds max. I misread the manual, where it says to never run the boat for more than 2 minutes, I didn't realize that was in or out of the water, due to the carbon seal and that evidently you basically can't start it at all without water because of the exhaust system. So now the question is, did I do damage, and/or how can I confirm whether or not this did cause damage? There was a decent bit of water in the hull from all the cleaning and rinsing.
