Before I invest in a my first do it yourself oil change, I was wondering what the best pump was to do the job. I know they have the 12V electrics vs manual. Any favorites? Also, the boat is WAY overdue for a change. I just bought the boat and the PO told me it had been 5 years, but the engine ( Yanmar 2QM20H ) runs like a champ. I have read that I should change the oil then run it for a while and then change the oil again. Any thoughts on this and how long I should run the engine between changes. I was thinking changing the oil twice would be enough, and then change it every 25hrs. I know 25 hours seems like over doing it but I used to work at an oil change place and I believe that the oil is the life blood of the engine and will extend the life of the engine.
thanks,
