G'Day NRF,
IIRC if you run a full flow spin on oil filter, you can stretch your oil changes out to 50 hours. However, oil is fairly cheap and it would be definitely in the engines best interest to change it every 25 hours irrespective of how many filters you run.
We use truckwash on our 44. It doesn't do a bad job, it even gets most of the lead deposits off the aft cowl
Cheers
