- 1978 Mainship 34 Perkins T6.354
I have the cooling system apart in my 1978 Mainship and was farting around with the raw water hose. I decided I'd open the sea valve and blow into it, to see if there was any resistance from fouling on the intake screen under the water. To my surprise there was air blowing out where the lid of the sea strainer meets the body. This was just my breath so the pressure was low. But I could imagine this was a significant loss of raw suction
I cleaned the mating surfaces and o ring and now it's fine. Might be something to check in case of overheating or loss of raw water volume.
This is a plastic unit with clear lid and a center knob to fasten it down. Seems a better design would is multiple clamping forces around the mating edges.
