Both my potable pumps were replaced last year as one was inoperable and both were badly corroded and probably original. I had someone do it for me so have to look close at the mounting when back late next week. Incidentally, had a boost hose on after cooler break loose from a broken clamp. Running at 2100 rpm, suddenly stbd went to 1500. Entered engine room, felt like an industrial fan blowing. Found busted clamp and hose disconnected. Shut it down, disconnected other hose end, reinstalled the hose with two new clamps, good to go. 5 minute trip delay...glad it was simple. Ordered more clamps to have aboard plus hi temp hose sealing duct tape.Jack,
The hose mounting I believe was Sea Ray's attempt to deal with vibration with mounting pumps to the hull. My original fresh water pumps were also mounted on tubing. When I replaced the fresh water pumps, I was able to reuse the OEM tubing. Unfortunately when I replaced the macerator pump, the bolts that were used to hold down the original pump were corroded. Instead of fighting with them, I just picked up new hose and stainless hardware.
Here are the fresh water pumps:
