There are two of them, located on the hull near both sinks. The valve/seacock on our ‘89 Catalinas’ is made of a plastic composite material believe called Marelon or something similar. Since this valve is flush with the hull, these valves are generally called seacocks and is a quarter turn ball valve operated by turning the lever. When the lever is parallel with the valve body, then the valve is open and when the lever is turned 1/4 (1/4 of a full circle/radius) turn so that the lever is perpendicular to the valve body, then the valve is closed. If this valve/seacock has not been operated for a very long time, like 1, 2 or more years ago, the seacock may be very tight or stiff to turn. This could be due to some sea crust or just an initial friction set between the ball and seating surfaces. Generally, once again operated, it then turns more freely. Sometimes, when my boat is raised out of the water for bottom painting, etc I sometimes place a little bit of grease on the seacock from outside the hull and then from inside, cylcle the valve to ensure it operates smoothly but this valve was probably designed to never require lubrication if regularly operated and it is possible that some greases may not be compatible with plastic material, so that is something to consider. Something to also consider before operating the seacock for the first time especially after purchasing the boat, is not to apply too much force to opening this valve - Obviously, it would be a disaster if this valve were to crack/develop a water path from it failing. Years ago, the design of this valve, how it was attached to the hull and its body material was revised perhaps a few times. From what I understand and perhaps others more in the know, can detail the material and design revisions thru the past Catalina model years but from what I understand, the ‘89 model has the best seacock design (to hull). and seacock body material - the body material and internals not subject to corrosion.
