I am going to assume that you are raw water cooled (your boat actually) since the early CAL 30's came that way and your boat is in fresh water anyway. It is possible that you picked up some crud that is blocking your water intake or that actually made it's way to the impellor (a filter placed before the impellor is a good idea). Shut your raw water valve and check the impellor. If it's good then pull the raw water hose and open the valve to see if you have a good flow. It's easy to suck stuff up into the thru-hull. I've sucked up small fish before and it can play heck with the water flow as well as with the fish. I added a tee to the top of my seacock with a plug in the top. This way it gives me a straight shot to clear any foriegn materials that get sucked up. By the way, I've owned a 1965 CAL 30 for about 14 or 15 years and I really love the boat (a link to pictures can be found in the link asking about the CAL 30's).
