Help needed!!!! with 1998 Johnson motor

[JTMaclain]

I have a 1998 30 hp Johnson motor. I was taking off the lower unit and when I disconnected the water pump I noticed that the gasket was cracked and flaking off. Should I replace the gasket or get a whole new water pump. Also after I put it back together and when I turn the propeller by hand I can hear the pump rubbing on the drive shaft. What should I do????????????????????????????????<br /><br />Thanks<br /><br /> Nick

Ahoy, Nick.<br /><br />Replace the gasket. I think the rubbing you hear is the result of the failed gasket and is the impeller rubbing against the water pump housing, rather than the drive shaft.<br /><br />We use less memory and time if we leave out "need help" and extra punctuation on posts. When you post we know you need help.<br /><br />Good luck.

Thanks, but can I just replace the gasket or do I have to buy a water pump kit?

I replaced the waterpump of my 30hp the other day.<br />I changed the whole thing, because the efforts probably to take off the lower unit for a second time make the costs of a complete repair kit worth.<br /><br />Nordy

You can buy just the gasket, after the impeller/pump is installed, only turn drive shaft in direction engine runs. You did put the impeller key back in right?

I bolted the water pump back on with the old gasket for the time being, but what is the impeller key?
