Fair warning, some of those are too big for the hull drain hole. I use a second piece of hose that has a fitting with a smaller OD and put it through the drain hole from the outside. Then screw the two together.

I went one step farther....I bought the hose and 90 deg fitting that fit where the oil pan drain plug went. I then ran this hose to a bulkhead mounted electric oil pump I picked up at West Marine. Wired it to the electrical system and now have a built in oil removal pump.

Now all I have to do is turn on the battery, open a quarter turn valve on the pump assembly and route the output hose to an appropriate container, and turn the pump on. Sucks it all out. Having the oil warm makes it go much faster.

+1 Mine will not go through my hull drain all the way. I just put it through as far as I can, sticks out about 1/2", and put the drain pan under it.

I bought the CP kits when I upgraded my 575's... funny thing was that those POS kits didn't fit through the garboard drains... I even added two separate garboards for them.

The Yanmars have the dipstick tube attached to the drain plug hole from the factory so I just suck it out of the tube with a big vacuum pump. I would imagine it wouldn't be that hard to adapt the yanmar tube to another motors drain plug with the proper fittings. I have 6LP's in case you want to look up the part at a yanmar dealer.

Second and third that one!!!
Bought the exact same ones, will not fit my drain plugs

Merc ones are a lot smaller hose/fitting, but I could never locate the Merc ones as they stopped doing that.

They work fine in theory, but my answer to oil changes was this. It works great on all fluids!!! Cars, trucks, lawn equipement etc.

I've got these on both my engines. You can hook a pump to the hose, route it out the bilge drain hole or drain it into a pan in the bilge then lift it out. I do the last method because of my staggered engines I can't run the hose our the drain hole from the forward engine. But, I've got room beside the engine for a pan. No Mess at all and you get all the oil out.

that's what i use ,too

I bought the cp
Performance ones too. Won't fit the drain hole. So i chopped off their end, and installed a barbed 3/8" fitting with a plug. That fits fine. And I have it pulled up next to the steering assembly and bracketed to the transom. Can't leak ever if it's 12" above the engine when not it use

we sell the MPI motor oil drain hose kits inwhich is the same set up as CP Perf. but the drain hose fits thru the drain plug hole. Also they swivel at the oil pan drain hole.
