Running on shore

Post by LandVF36 »

In past years, I've ran the engines in the yard before dropping in by connecting a garden hose to the intake hose before the external raw water pump.

This year I purchased one of those "plunger" devices that you connect a hose to from below. It didn't work out so well. I could run the engines at idle, but when I started to run the RPMs up, they started to overheat with anything over 1700.

I think the issue is the 3/8 restriction of the hose going into the plunger. Anyone have a similar experience?

Yes-

Average flow out of a typical garden hose is around 6 GPM. I's been my experience that this barely keeps up at idle and my engines at 2000 RPM are drawing easily 20-30 GPM.

Happy day! Splashed in today around 10AM. Motors ran fine, at any RPM, not heating problems. I made note of flow out the exhaust while connected to the hose vs idling at the dock. About 3X more water at the dock with an unlimited supply! I must pump pretty close to 30 gpm

Only about 3 mi from where I drop in to my slip and and everything went perfect! Its now officially summer as far as I'm concerned :lol:
