can a posting
title like that be completely legit?
Having been working 90 hours weeks for what feels like forever I've been starting to get the boat ready to go out again.
Here I'm going to own up to being bad. Ever since we got the boat I haven't changed the impellers. So long as the running temp seemed okay and water
kept coming out the back I've pushed this to the back of my **** list. Why? Because there are warnings in my manual about doing it wrong leading to needing to rebuild
the pump. That and fear of the unknown.
This year I decided to fix that. Time for a whole new approach to this. Time to conquer the fear.
So I crack open the pump case with a [small] bucket underneath to catch the expected sea water
. Here comes the water. Quite a bit of pressure there - wasn't expecting that. Hmm, one bucket later still have pressure. After three buckets I seal it back up again.
I was expecting the flow to stop quite quickly - looks like the pump is below the water line but fairly high in the overall raw water
I make sure the anit siphon device is cracked open (but lets face it the exhaust
output is above the waterline) and that the sea cock really really is closed.
Try again. This time I push the sea cock open and closed while watching the flow, no real change.
I tried tightening up the sea cock, still no change though there is now decent, but not excessive, friction on the handle.
Is the cock broken or am I missing something completely obvious?
is a Universal M40 / 5432 - the pump a Sherwood something or other and the sea cock unknown, fairly corroded looking but the metal under the corrosion
I wasn't planning on hauling out until after the summer - do I need to change plans?
Oh while I was working out how to tighten the sea cock I threaded the lock nut. It still holds the handle in place but not tightly and I wouldn't want to use it as support in an emergency
