Raw Water Flow Meter
Has anyone ever attached a flow meter to the raw water line just before
discharge? I would think if you could get a baseline reading with a new impeller or go by the flow rate of the pump at a given rpm then if it drops it would indicate an impeller change or it would aid in diagnosis of an overheating condition. Maybe even a remote display. My pump is supposed to produce 26 gpm @ 1800 rpm. I have no idea what the output really is. Any thoughts? Phil |

Put a strainer in the intake line and locate it somewhere with easy visibility through the clear lid to check flow. I have a Vetus strainer http://www.vetus.com/frame-cat.htm with the top protruding through the engine cover where it is easily visible with a quick peak down the companionway. As a bonus it makes it very easy to run the engine when out of the water by feeding the strainer from a garden hose -- great when winterizing or preparing for launch. Ryk |

A low pressure, pressure gage will do the same thing. There is also a flow
sensor for fire alarms. Mike ********************** Has anyone ever attached a flow meter to the raw water line just before discharge?

Just a thought ... my outdrive impeller supplies my V6's water pump. Water
flow from the impeller I would guess would vary dependent on the engine temperature, any resulting restriction caused by the thermostat, and the V6's water pump. If it was me, I'd install an audible alarm/water temperature gauge. And when that sounded, I'd shut down and then figure out where the problem was. "MIDEMETZ" wrote in message ...
