Hi, I managed to lose one of the centerboard stops (must have come loose and fallen down the centerboard slot?). I figured I'd just grab some 3/8" ID heater hose from local automotive store. The original hose is over 3/4" OD but the hose at the auto parts store is about a 1/16" diameter less. Think it matters? If so, anyone know where I can find a proper replacement (locally)? I know Catalina Direct has a replacement kit for the stop, but I'm hoping to take advantage of the few remaining sailing days I have left. Thanks, Brendan
