I'm sure this is a really easy question, but it got me stumped this morning, and I was hoping someone here could shed some light on it for me.<br /><br />This morning, I attempted to change the waterpump impeller on a 25HP 1999 Johnson. I removed the prop, the impeller screens, disconnected the shift linkage, and removed the lower unit from the motor. I took out the driveshaft and installed the new impeller in the cup and put the driveshaft back in. Things got interesting when I tried to put it back together. My question is twofold:<br /><br />1. How do you get the water line hooked up? On this motor, it is a rigid copper tubing that slides into a rubber sleeve. The other end goes way up inside the housing to another gromit. The tube does not line up with the water input as the lower unit slides back onto the assembly. Are there any secrets here?<br /><br />2. Water hookups aside, the "lower unit" comes within one half inch of the housing and seems to stop. The driveshaft if properly aligned, because if I spin the prop it is spinning the crankshaft. Am I supposed to just start tightening the nut on the bolt that is at the rear of the lower unit and let it pull the two together and then install the four bolts?<br /><br />Thanks so much for any help you can give me.<br /><br />Kent
