How do you drain the oil from your boat?

[Evening Shade]

I have a 2011 SANTE 210 with ZR 450. Yesterday after we left the lake I wanted to change the oil while it was still warm. So I ran the quick change hose out the drain hole in the hull, removed the cap and oil just came out as a trickle and then stopped. I left it sitting this way over night with the hopes that it will be completely drained by today, but I'm very skeptical. I won't know until I get back up to the boat shed later today.

So my question is: How are you guys extracting the oil from your boat? Also, the oil filter appears to be hard to get to as well. Does anyone recommend a particular tool or wrench to remove the old filter?

TIA

Pump out the oil using a hand or electric based pump. Many varities. Takes about 5 minutes.

Vision, Do you pump it out of the dip stick tube or from the quick change hose?

[BoardSkier]

Pump it out the dipstick. Use a manual pump. Takes 10-15 min. Make sure engine is hot.

+1 for pump out through dip stick. Electric pump is nice so you can pump out filter as well and not have to attempt to carry an old filter full of oil out of the boat.

So going through the dipstick get oil out the filter also? I have always used a drill pump through the drain hose, works great

Sorry I should have given better detail. After I un screw filter I pump the filter as well so I don't have a big of a chance foe a big mess.

Make sure the drain hose is not kinked as it routes down and toward the bilge drain. On my 08 the hose makes a significant turn and will kink if you don't watch for proper routing. I usually loosen (but dont fully remove) the drain plug on the hose and then route the hose accordingly. It should flow fairly well if the oil is warm. I have a short clear section of tube that I add to my hose once through the drain plug that keep the mess to a minimum.

Paxdad,

My drain hose may have been kinked which wouldn't allow the oil to flow. I'm not sure I could even get to the oil pan to see it is kinked because the engine compartment is so tight. Maybe if took one of the hard tanks out I could see the routing of the drain hose, but I don't think I want to go to that much trouble.

I ended up sucking the oil out of the dipstick tube with Top Sider suction can that I used on my Cobalt years ago. It probably took 30 minutes to suck all the warm oil out.

For the oil filter, loosen the filter then take a large ziplock bag and place it around the filter. Continue to unscrew the filter and let it fall into the bag. This will catch every drop of oil.

My boat has an NPT fitting (I think the male end) on the end of the drain hose. I bought a swivel female(?) NPT fitting to hide barb adapter and attached it to the end of my vacuum pump hose. This way I leave the drain hose clipped to the top of the engine and I thread my vacuum pump fitting on to it and suck all the oil out. No mess and no worrying about getting a drain tube stuck in the oil pan.

Just did this in my 03 SANTE Saturday. Borrowed a friend's manual pump, sucked about 4.5 quarts out through the oil drain hose. Loosened the filter by hand then put a gallon zip lock bag over it and removed it from boat. My oil drain hose would have fit through the drain plug but I just ran it up and out the back of the boat where hinge for the engine cover was. Took the pump hose and ran it over the platform up to the hose. Easy easy. Took me 15 minutes. Local dealer charges ~$100 to do the same thing. What a ripoff.

Slidin out,

What brand of manual pump did you use and how did you connect it to the oil drain hose?

I'll have to look when I get home today if I can remember. The hose that came on the pump was a little too large to fit in the drain hose of the boat. But it came with another smaller diameter hose. I put the small hose as far down the boat drain hose as possible. Then I took some rubber vacuum line hose from the parts store and made a coupler for the two different sizes that came with the pump. Since the smaller hose slid freely into the vacuum hose I took some scrap wire I had around the house and twisted it tight around the vacuum hose to seal it off. Also twisted some around the end of the boat drain hose to seal it off better. About 6-7 pumps and I had oil flowing out into the capture vessel on the pump. Took about 3 minutes to completely drain it. No mess in the boat at all. Filled the boat back up with oil, reversed the pump and pumped all of the old oil back into the empty jug from the new oil. Put a gallon zip lock bag under the oil filter when taking it off so I had absolutely no mess from the pump or oil filter to deal with. Barely got any oil on my hands. Bet I can change the oil in about 15 minutes tops next time.
