I've been working on a 1966 OMC Stringer, trying to bring it back to life from the corn-field that it spent last winter in.
This summer, to try to determine what I was in for, I ran the engine a few times on the trailer, with the garden hose hooked up to the Flush adapter on the drive-unit pivot end-cap. I understood that the water flow was necessary to keep the lower-unit water pump from burning out.
I wasn't able to find many details about using this hose adapter for this purpose, but what I found said that, while the engine was running, to simply keep a steady stream of water coming out the exhaust and the tattle-tale holes. Is this correct?
Now I see, according to the OMC Service Manual cooling system section, the water-flow diagram shows the water going up and forward, from the vertical-drive and into the engine.
My question regarding this is, how does the Flush-it hose-hook-up keep the lower-unit pump from burning out if, at the Flush-it location, the water-flow is away from the pump and into the engine? ie the water goes toward the engine at that point in the system, and eventually goes right on out via the exhaust.
Also, if I or a previous owner has already burned out this pump (knock on wood), what indicator would I have before the boat went into the water? Do I have to stick it into a drum of water to see if it still pumps, or does the hose hookup method reveal something?
I appreciate any light anyone can shed on this for me.
