"I've been working on a 19
"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?
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, and eventually leaves via the exhaust.
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."
