I have a 96' 40 hp, 4cyl mercury tracker that I bought used about four years ago. I noticed the last few times I took it out the water output from the "peehole" gauge was pretty weak but sufficient to keep it cool while running (moving anyway). Well with duck and deer season approaching I decided I should replace the water pump. I have a few questions that I was wondering if ya'll could answer. First off I have no idea of the maintainance of the motor before I got it. In all likelyhood the water pump on it is original (96). Also I'm a full time veterinary student that is VERY POOR!!! I spend money if I need to but try to be economical!!! The questions are as follows:<br /><br />1) Should I just replace the impeller or get the whole kit? (impeller $9, kit $57) Of course I'd like to get away with just the impeller but if it will likely fail sooner because I failed to get the whole kit I won't like that in the long run.<br /><br />2) Do I need a manual to do it? I am fairly good with motors (carbs and all the upper unit stuff) but I've never messed with a lower unit. I really don't think I need one personally... anybody do it without one???<br /><br />3) What other things should I do while I'm in there. Obviously I'll be changing the lower gear lube, but will I need to replace any other gaskets that will be removed to get to the pump? I don't want to skimp on a $.50 gasket or drain plug!!!<br /><br />I'm sure I'll have other questions but I think I've covered a lot so far.<br /><br />Thanks!<br /><br />Brent
