Hook your boat up to a fake a lake pump or your perko flush via a hose.
Start and run the boat to get up towards operating temp to allow the oil to thin.
There is a small hose that runs from the bottom of the oil pan for draining. You will find it hooked to a metal ring to keep the bottom of this hose higher than the oil pan. You can most easily find it by entering your port side locker and removing the sidewall and then tracing the hose from the bottom of the oil pan.
Turn off the boat and push this hose towards the drain hole at the back of the boat. It may not reach out but should reach close. Run a little of your extractor hose up the drain hole and connect the two hoses. The oil pan hose is threaded at the end. I purchased a variety of threaded barb hose fittings to ensure this connection is air tight.
Create pressure with your oil extractor and the oil will drain from the pan. This may take a little bit of time. When done recover the drain hose and secure it back on the metal ring.
Once the pan is drained I remove the oil filter. This is difficult and potentially messy. I like to use plastic gloves and put a garbage bag down to collect any mess. An oil filter wrench will help remove the filter. I have seen filters so tight that they were removed with screw drivers punctured through to create a handle. The oil filter is best accessed from the starboard locker.
Replace the oil filter with a new filter filed half full with new oil. I believe some wipe a little bit of oil around the seal of the filter as well.
Pour new oil in. You can see a bright yellow cap on the engine not far from the oil filter. I believe it is 5.5 quarts. I pour in 5 and allow everything to settle for a bit. Its tough to get every bit of oil. Check the dipstick and use the remaining oil to get to the appropriate range. If you overfill drain a little as you did before. If you are not confident, restart the boat when ready and bring it back up to tempurature. Check the oil level and add/drain as necessary.
Transmission fluids are easier. There are two red twist dipsticks on the transmission under the sliding rear seat. Pump them both empty using your extractor with the hose directly into the fluid cavity after removing the dipsticks. Replace the fluid. I don't remember the quantities but one is roughly twice as large as the other. Check that that the appropriate amount of fluid has been added by setting the clean dipstick back into its slot. Do not screw the dipstick in, you are meant to set it there on the threads to check.
That's how I do it. Others may chime in and say otherwise but I've had no issues. I don't think I missed anything major.
Just did mine after wRmimg oil and all I did was leave the 12 mm open end wrench I used to hold hose fitting at top to disengage the hose fitting from cap with clip on the valve cover and wrench held hose up and in place. Shoved extractor hose down tube and ran pump. No fitting no hassle
