Does anyone flush there motor after being on a silty river the the Mn?
I have an I/o and in my head I can see the fine silt settling in the water jackets of the engine. With an outboard those are “self draining “. But an I/o is just a car engine and not self draining.
As long as you can get to it before it drys into concrete, why wouldn’t you if you had an easy way to do so all set up?
I guess you could “test” it by filtering the outflow after being on the river for a day.
If you set up a white filter of some sort (say an old linen sheet maybe?) and it turns all yellow and gritty, I would guess that would be conformation!
silt is a vegetated matter, it should flow through,now sand is abrasive,thats no good for a impeller on a outboard. on a inboard it would harm the water pump.the few inboards i putzed with in fresh water never had any water system clogs or damage i knew of from silt.water pumps are fairly easy replacement on a engine BUT1 put that engine in a compartment thats small offta!.what you runnin as a boat? motor?
Of all the things I've ever done,
I aint never had Too much fun.
