Problem water pump Yanmar 2GM

"Jeffrey P. Vasquez" wrote in message new You can check most pumps by taking the cover off and turning the engine over with the starter while holding the fuel cut-off. If the vanes don't turn, there's a shear failure somewhere or a missing key, and that's your problem. If they do turn - your pump is almost certainly OK. Back to the partial blockage . . . jUST adding a little, Did you replace the wear plate on your pump? Is it a jabsco? If it is a jabsco and you did not replace the wear plate that might be a good place to start. Are you getting the same amount of water out of your exhaust? If so than its you fresh water pump, or like jeffery said perhaps your heat exchanger is clogged up. Good luck Joe Have fun. Maybe someone who knows your Yanmar will give you a better story. |
