Replacing impeller on 1993 Johnson 175

[Disturbed]

Is it hard to replace the impeller on a 1993 Johnson 175? Twice at idle, I have gotten a temp alarm. The boat sat for about 6-8 months before I bought it and I'm sure it probably needs to be replaced. I have a P/N 5001593 for just the impeller or 5001595 for the entire water pump kit.

Keeping in mind, I'm a novice boat owner and the only thing I have done ot an outboard engine is drain and replace oil from the lower unit, replace the spark plugs, and a simple fuel gasket. I have however pulled and rebuilt a Chevy 350 from a car by myself, so I am technically inclined.


Also, I don't mind paying someone to do it if it is going to take me hours and be a pain in the @$$.
