Apologies for posting a question which is not strictly S&S Swan related.
I would like to change all the sea-cocks in Four Winds to Blake sea-cocks. But I am in doubts on the correct size to be used for the cooling seawater inlet. The sea-cock used at the moment is in terms of size something in-between the large and the small Blake sea-cock. (I have not made a measure yet) I have tried to found the recommended diameter of tube on Volvo Penta website but without luck. It seems that it is only the small Blake sea-cock who have the inlet “screen” as a rough filter – not the large one?
What size of Blake sea-cock do you have for the raw water pump inlet?
My engine is a small three cylinder Volvo Penta 44 HK. The cooling water pipes are quite small in diameter.
