I would like to continue this thread if I may. You all are describing a problem I have with my Perkins
When motoring in rough conditions or even moderate swells, my raw water
intake sometimes sucks air, so that I end up with an air bubble in the raw water strainer, which the raw water impellor will not suck thru. Resulting in the engine overheating
To get her running again, I close the seacock, open the lid on the stainer to bleed the air out, then close it up again. At this point I usually prime the impellor with soapy water just to get things moving.
In rougher conditions, this is a bit of a pain. And likely only resolves the issue until the next time it sucks air.
So what I'm wondering is, is there a way to permanently resolve this issue? Should my impellor be capable of sucking the air thru? I'm at a loss. The only thing I can really think of is to move the thru-hull to another position in the hull
, something down lower. But I can't imagine that the boat
, a Morgan
38, would have such a design flaw.
