Starting Mercruiser on Engine Stand **UPDATE**

Re: Starting Mercruiser on Engine Stand **UPDATE**

I ran the engine for an hour at 1800 RPM's for cam break in. The hose never sucked flat, engine never over heated and I made sure that the thermostat was working fine by just checking water temps with thermocouple and multimeter on the temp sending unit.

The hose never sucked flat,

You don't have a raw water pump on your engine, so you just used your hose water pressure as the pump. A Volvo or Merc Bravo pump will suck most hoses flat at around 1800 to 2000 rpm.

Don't ya just love the sound those 350's make out of the water? Kind of a Tim, The toolman Taylor kinda moment.
