We have a 2015 precept 35un I just did a filter and oil change not bad. But next time i would like to try a transfer pump of some sort. Because of the filler location all I had was a squeeze bulb. I have tried those drill style before they never seem to work anyone ever figure out a better device.
Most boats with inboard engines require a pump to change the oil since you really can't drain it into a pan and you don't want to drain it into the bilge. Try the link to Defender.
You can also buy an electric transfer pump along with a couple of hoses and draw oil out and pump fresh in. Look on Amazon the cheap ones are about $60, or as Teamfoxy said you can buy a self contained marine setup but those are really just meant to drain oil, they would take a lot of cleaning before you could pump clean oil back in.
