Water Flow Problems on a 50 Yamaha

[kolortyme]

Even after replacing the waterpump seals and impeller I am still not getting water flow through the pee hole. When I first crank it I get a weak stream then after 15 minutes or so of running @ cruise speed in the water I get no flow. Now I am not getting any flow when idling. Does this model have a thermostat and could that be problem?<br /><br />thanks, Will

I dont know what year yours is, I believe all motors that size by Yammy have a t-stat, I could be wrong.<br /><br />I had the same issue on my Suzy 55 and it was a clogged t-stat and it needed a good flushing. I flushed mine, cleaned all the buildup off my t-stat and it works perfect.
