"water pump" help

[johnnyxxxx]

i changed my water pump! the motor is a 1973 evinrude, when i took the pump housing off i noticed ,that the old pump looked new, nothing wrong with it ok. however, why i changed it is there are no water coming out of the holes. enyway, i hooked a water hose to the tube going up inside the motor, i found that the tube is busted,i need to change the tube, but i can not get it out... how do i get the little tube that carries the water to the motor????

mornin' jonny,<br /><br />don't know your specific motor but in many cases, you'll find that tube will be easy to replace after you remove the power head.

Johnny,<br /><br />Sorry but you will have to remove your powerhead to change the tube. It is connected to an exhuast tube that fits inside your exhaust housing,<br /><br />Pull the powerhead and then remove the exhaust tube, the wtaer pipe will then come out.<br />It is not really a difficult thing to do, but only time consuming, get a SELOC repair manual, and go for it.<br />If you have any doubts of course take it to a mechanic.<br /><br />My only question would be, what caused the copper tube to break? Thats not a common problem.<br /><br />Pat

Re: "water pump" help

its the copper line that comes out of the water pump housing.

Hi John...<br /><br />If the copper line from the pump to the motor is busted, then boatman is correct. You will have to pulle the power head to replace it.

Re: "water pump" help

well i pulled the power head off and got to the copper tube,and guess what i found, the hole in the tube was a "factory hole", it was about 1/8 inch in dia, all that work and nothing wrong with it, enyway i learned a lot.. ps: can enyone tell me what the hole is for?? also this motor has no pee hole, how much water should be circulating through this motor? thanks johnny

This is just a guess so take it with a grain of salt.If this is indeed a factory hole in the upper end of the waterpump discharge tube it may simply be a pressure relief hole intended to accomodate extra flow until T/stat is fully open.

Re: "water pump" help

unless someone that owned the motor befor i bought it, drilled a hole in the copper tube, its a factory hole. enyway yea you are thinking the same thing as me for the reason for it, thats the only logical reason...
