Am having problems getting a good water flow through my 78 30 hp . the pump does not seem able to overcome the exhaust pressue and the tell tail (pisser) fitted to the top of the engine has no output......presently have the pump on the gearbox in a bucket and am driiving it with a drill ...all the pump is under water and has new 10 blade impeller ..I am told by my marine supplier this is an upgrade on the 6 blade. a good 6 blade gives similar results. The pin is in place driving the impeller and the shaft seal is good.
Output is not high ..you could **** almost as fast ....any ideas how to judge the output or anything stupid I have missed ....
Thanks in advance
