I just bought a 2009 puma with a yamaha 250 HPDI series 2. The gauge is pegged all the way to the right, past 30 psi, and never moves. It is the orange and black yamaha gauge, I assume it is the original. It has the two wires for the light and a clear tube with a brass bolt on the back. Any suggestions on how to repair? My first guess would be to replace the gauge? Thanks, Dean

Impellers have no effect on the gauge if the gauge works as they pull through the block. The gearcase is not connected.

I realize that the impeller does not have anything to do with gauge but can someone tell me where and what to look for in trying to find the water pressure connection that is disconnected? Could I have accidently disconnected the cable or tube or whatever carries the information to the gauge, while working to replace the impeller?

I dont understand the statement “the gearcase is not connected”.

The only thing that you could have done is not stabbed the connectoin tube between the gearcase and the crank. That little plastic tube (3″) aligns everything and lets the water flow there. You can drop the case and check the connection. You should not have been around the water pressure connections.

So if I did that (missed alignment on the water tube), the motor would still cool properly? But the water pressure gauge would not work? Because the motor works fine, at all speeds, with no alarms, after I did the impeller replacement. Thanks for the help, and Im sorry Im not very experienced with these things..

No it would not cool properly.

So if the motor appears to be cooling properly, because Ive run it for at least an hour at various speeds including idling, and rpms up to 5,000, then its not the water tube, correct? Then is it simply disconnected somewhere? either at the motor(wheres the connection), or under the dash?Or is it a tube that could be clogged?
