Re: How much water should shoot out that little hole...
When I do the water pump, I also do the housing too since you can usually find the whole thing as a package. I ahvent done a 50hp but have done a 70 hp Chrysler which is similar. The manaul I have used which is pretty good is the Seloc manual and they outline everything very well and tell you what to do and also more importantly what NOT to do. Regardless what manual you use there is a trick that we learned when getting it all back together. Getting it apart and putting a new waterpump housing or impeller is the easy part, getting the whole thing back on the engine and the shaft lined up is the hard part. <br /><br />Get a roll of wrapping paper, like from Christmas and remove the cardboard tube from the middle. Slip it up into the inside of the engine and over the hole which the driveshaft must go into and get someone to hold it in place. Insert the driveshaft of the unit yu have out into it and slide it up into the cardboard tube, using it as a guide to get it into the hole in the powerhead, once it matches up with the splines and inserts into the hole, leave about an inch gap and make a tear in the cardboard tube that goes along the spiral way it is made. Pull it down so it tears the roll and comes out in a curlyque, all the while holding the lower unit up in place in the power head. The wrapping paper roll should come out completely just like a really long curly french frie and then push the lower unit up into the powerhead the remaining inch and wala, it's in. My girlfriend came up with that idea after I spent hours trying to line it up and get it fitted in right blindly.
