Alex,
I change my impellers annually (in the spring) that's why I don't worry about pulling them in the fall. I would think the only reason to do it more often is if you were concerned they got damaged somehow, sucked sand, seacock closed, etc.
I also change my genny oil mid season, this year I did it at 154 Hours. I should have waited a little bit longer because end of year time on oil was 205.9.
It doesn't bother me too much because of the oil report from Blackstone:

All wear read below averages for this type of engine, which is a very good indication of normal wearing parts and is especially good considering this oil was run longer than average. Universal averages show normal wear after about 120 hours use on the oil. Insolubles (oil oxidation and soot due to heat, use and blow-by) were low at a trace, showing good oil filtration. No fuel or anti-freeze was found. Low silicon shows good air filtration.
