Re: impeller replacement
$700!!!!!! What a crock!!!!<br /><br />I really don't know what the going rate is, because I've always done it myself. However I do know that $700 is rediculous.. I would think maybe $150-max...<br /><br />To replace it yourself all you will need is the impeller and a new pump housing gasket (assuming everything else is in good shape).<br /><br />You will need to drop the lower unit. THere are 5 nuts on studs that need to be removed and one bolt that is under the trim tab at the rear. Once the are out the lower unit will drop out. You will have to disconnect the speedo tube at this point to totally get it loose. The water pump is located around the drive shaft and the pump cover is held in place with 4 fasteners of various size. Remove the bolts (or nuts) and pull the housing up the drive shaft. There is an impeller key that fixes the impeller to the shaft, find it and keep it as you will need it later. The impeller will be inside the housing/cover, pull it out.. Next, replace the gasket and slide the new impeller down the shaft and use the impeller key to fix it in place (you will see how it works). Now use some lubricant on the inside of the pump cover, just a little thin oil will work. Slide the cover over the shaft and down onto the impeller. It won't slide over it easily however, you have to turn the drive shaft "clockwise only" and push down on the cover for it bend the impeller blades enough to fit in. Again, clockwise only! After that here is a rubber washer that goes down the driveshaft and sits on top of the housing (forgot to mention that earlier).<br />You must tighten all the fasteners to a specific torque, I think the large nuts are 30 in-lb and the smaller bolts are 20 in-lbs. <br />There is a guide tube for the water pump pick-up. It is white and is probably stuck on the pick-up tube, pull it off and reinsert it into the water pump cover exit.<br /><br />Now you are ready to reinstall..
