Does anyone have one of the older model bronze raw water intakes with a large square nut horizontal shutoff. I'm interested in changing mine out, but I'm not sure which way to turn it it to shut the valve. I'm afraid to remove the hose until I know it is working properly. The boat is in the water. This valve is very difficult to turn and requires a LARGE crescent or pipe wrench and quite a bit of torque to move. Bluewater Coastal Cruiser was built in 1986 and these large 1" thru hulls are original to the boat. If no answers, I'll attempt to post a photo later. Thanks

Yes, it does have a nut opposite the large square "nut" (lug?) whatever you call it. I'm so afraid when I put torque on it I'm in danger of breaking the seating in my hull. I'll try loosing the small (I think 3/8") nut on the other side. Guess I could loosen the hose (I believe 1" ID) until it stops leaking as I rotate the big lug. Really need to change these to ball valve at the next haulout..Thanks for the tip.

Is there provision for a grease nipple on the mounting?
THese things need to be greased and serviced periodically or they can stiffen and seize.
To grease, the valve needs to be turned on so the hole is inline with the water flow and the valve ball presents its side to the grease nipple.. You will likely require a GOOD grease unit., not a cheapy as you will need to use some force on the gun.
It won't require gobs of grease.
Work the valve handle back and forth a few times and then do the other side.
Or wait untill you haul out end then do the same thing.
Once working constant operation of the valve should keep it clear for quite a while but it should be done yearly. The greasing.
