Hi Andy, Yes I actually have a new engine water pump. Cheers, Murray

PS - I have cleaned out the heat exchanger as it was all crusted up from sea water so there are no blockages through the cooling water intake circuit.

Hey guys thanks for your responses. I do now have a new water pump. (the new ones have a SS boss as opposed to the light weight one you see in the photo. Since writing my post, I have been able to find out that the impeller is driven by gearing from the drive shaft (helical). I don' think the thermostat id faulty as the water out the exhaust gets so hot you can't touch it. I have inspected the impeller and it looks fine bu the Jabsco service assistant has told me it is likely one of two things; a worn back plate or an impeller that has expanded and therefor would need replacing. There is a plug that should be fitted at the from of the impeller to stop wearing and fill and air gap in the assembly so that the vacuum in the impeller housing works better so I am going to replace the impeller and make sure the front plug is in place. cheers, Murray

Hi everyone, I have a Ford 2711 E and would like to know the gearing between the engine drive shaft and the impeller used for cooling through the heat exchanger. I am having cooling issues and am wondering if there could be any slippage occurring between the 'motor' and the connection to the impeller pump. If anyone has an exploded diagram or can point me to one that would also be very helpful. I don't have a good photo of it but it is in the bottom left (out of sight) of the photo. Thanks in advance Murray
