I might be doing something wrong but I've just bought the boat and have her out the water on a hard stand, she starts on the button but with a hose in the main inlet it won't pump it out the exhaust, so I took the jabsco off and it has a metal impeller and all looks good but even back filling the system it won't pump, please help !!
Not 100% sure but id imagine those metal impellers wont suck if there is air in the system it will probably be ok once sat in the water I guess you can see the flow in the filter to double check
From memory, metal impellers are the dry run type to allow a Rib to be run up in the davits. Usually when running up you would place a tight fitting hose in the intake, so it does not suck air and effectively force feed the pump. It should be ok in the water.
Alternatively, is there an in line valve in there that is switched off??
