OK y'all, I'm the OP. I went by my dealer (about 25 miles away) and bought their replacement, a Rotary part # 19-5909. This is a little deeper/longer than the original stubby KAW. Should be easier to access ... the stubby KAW had a little challenge to get a filter wrench on it.
One thing I discovered that I didn't like was the drain plug was plastic. I sure wish it was cast iron ... definitely no torquing the plastic!
Love my KAW engines, I've always bought Kohler and Honda.
Thanks all.
