I'm thinking that this is a good idea! Could either just let the hose hang loose and connect to the extractor when needed or plumb it into the Reverco line for the engine drain (with a valve on each line).I think the only downside may be getting the last little bit of "crap" off of the very bottom of the case. I used the vacuum extractor for the 3-4 years we owned the QSCs and never an issue. If I had to do it all over again, I would have drained it with the extractor, removed the drain plug and inserted a fitting with a hose on it. Next time, hook up to the hose and pull the fluid out of the drain. This is what I have done on the current ones.
As for the interval, we are on a freshwater lake and typically put 50-75 hours on the boat/year. I always change when purchased and then change them every other year. Fluid always looked new and never anything on the filter/magnet.

As for the 'last bit', given the volume of oil (around a gallon) vs the residual in a drain hose, I'm not too worried about a very small percentage of old oil going back in. For me, making it easier to do, I'll do it when I change the engine oil ... which will be more frequent than I'm doing it now!
