replaced the impeller on our generator over the weekend along with adjusting the choke mechanism and replacing the zinc. (Note to anyone considering replacing the impeller on this unit themselves - this is about the easiest thing I've ever done in the ER of this boat. Save a couple of hundred $$ from the dealer and do it yourself. Found the impeller/o-ring online for $28.)
take a look at the picture of the old impeller...this is with only 28 hours on the unit...! The lesson here is that maintenance schedules that call for maintenance at x hours or x months need to be followed on both counts. The Kohler tech I spoke with said he recommends replacing the impeller every year if it is heavily used, every other year otherwise. This one went four years. I did get some of the broken pieces out but I think a few may have made it down to the muffler or (hopefully) out with the raw water discharge. I take the hoses apart and inspect at the end of our season when winterizing.
The genset now has new plugs, new zinc, new oil, new filters, zinc and impeller. The choke adjustment was critical to getting this thing to not shut down when starting it.
