  Blake sea-cock size for raw water inlet  
 

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.

Dear Björn
Here you can find some information.
Pls note that Nautor does not install screens for the sea cocks.
Kind regards
Lars
