I had someone do the last change because the boat was in a remote location and I didn't have time before I went to pick her up and take her home.
I bought the filters and Volvo ATF to do it myself as I am doing most of the maintenance myself. I bought a oil change pump and plan to use it to extract.
@Jetstream I didn't know there was a drain! That will make it easier to get the last bit out as the shop that did the change could not extract it all and did not know there was a drain... so you don't want to refill through the dip stick hole? The big question is how much do you add as I've found the dip stick reading to be less than easy to work with... or I guess if you use the drain plug, you know you got it all out and can add the amount the manufacturer says the unit holds...
As a side note, how often should the transmission fluid be sampled and sent out for analysis? Since mine were basically new, I was doing every 100 hours and was getting some high metal content. Consensus seemed to be that it was normal and both were wearing the same. No one could tell me what normal metal content should be and how often to check. I can just ignore sampling and change every 200 hours I suppose (or sample right before the change). I have my oil analyzed every 50 hours may switch to every 100 hours for the first 200 hours and then every 50 TBD.
