I'm currently removing all my raw water intakes to replace with flanged seacocks. My current setup consists of apollo ball valves attached to bronze thru-hulls for the engines, genset, a/c, head intake and head discharge. I'm a bit confused with the size & measurements of my current valves. The ball valves for the engine intakes read 1-1/4", which i believe is the I.D, but the intake hoses are 1-1/2" I.D. Same happens with the genset, ball valve is 1/2" and the hose is 3/4".
I'm buying all my parts from Lewis marine and now i'm not sure what size seacocks and adapters to get. I was thinking on the FBV full flow series for the engine intakes but don't know if it has to be 1-1/4" with a 1-1/4 thread to 1-1/2" hose adapter or just a 1-1/2".
My engines are 4lh-ste's, so i think some of you guys are running the set up i'm looking for. Any input will be very well appreciated.
Im looking for a setup very similar to what i believe Capt. Pat used on hancock's b31. Maybe he can chime in with some details on what size seacocks and 90 deg. adapters were used.
Here's the pic of capt.Pat's install
