Does this include the connectors or is just the hose?
This only includes the hose.

Hello, i have a 95 wellcraft 3200 martinique. Im looking for the hose that goes from outlet side of the seacock to the engine. Its the raw water cooling for the engine. I dont have a part number. Is this the hose?
We will have to know your engine, not your boat in order to match up parts. Best to have some kind of serial/model number as well.
