I am about to try to change the impeller on my mid 90's 15 hp Honda.I asked the dealer and he said it was easy, but he would charge me for an hours labor($80), but said I should be able to do it w/o any problem. Looks to be simple, but sure would be nice to have a schematic to look at. Anyone know where I can find one online quickly? I haven't been to the library to look yet. The weather here is about 20 degrees and blowing 25-35 mph currently, so I will wait until it warms up a little bit.
