What are these cables in the bilge

[eigcpa]

See the attached picture, can anyone tell me what these are, what they are for and if maintenance replacement is called for? If maintenance is required how is it done.
Thank you

If I'm not mistaken that's a drain hose for oil changes. You push that brass end out the drain plug on the transom, twist off the top and the crankcase oil will drain from the pan. I had that setup on my 2002 Crownline with the same powerplant. Much easier than sucking oil out through the dipstick, BUT the boat has to be out of the water.

BTW, that small piece of wire that is broken is supposed to be connected to the inboard side of the drain plug in the transom. So when you take the drain plug out the hose is connected to it and will also come out for easy drainage.

There also appears to be a disconnected green bonding wire laying there as well. It needs to be re-connected to its original location..........where ever that is.

I think that bonding wire has a ring terminal on the end of it and is attached to the back of a thru hull bolt that is holding the flage for the bilge drain plug, bonding the plug and flange. Looks like it is still hooked up to me?

That's correct. It's the garboard plug bonding wire.

Ron’s answer is correct.

Its for changing the oil when you are on land. Its slow. Too slow.


I am going to bet that few people use this feature. Most people suck the oil out.

Thanks to all, always great to know I can get answers from a very knowledgable group of people.

The boat doesn't need to be out of the water- I had the same hose/plug setup on my gas inboard- I removed the plug ( after raising the end of the hose above the level of the oil pan), slipped another hose with an inside dia. slightly bigger than the oil hose over top of it and tightened it up with a wire tie. Attach the other end of the "extension hose" to the drill pump...pump it out.

My generator has a hose like this clipped to the side of the block, but I still use the dipstick. These hoses are attached to the drain plug of the oil pan so they are located at the most dependent point. Whatever works for you.

I didnt' use this hose on my Crownline but if the oil is good and hot, is it still too slow to be useful?

While we are on this subject, my Westerbeke generator is also equipped with a drain hose. A number of years ago I picked up the pipe fittings required to screw a male garden hose adapter with a removable female cap on the end of the hose. This makes it easy to attach the female garden hose adapter on my Jabsco oil change pump to the generator. I have the same fittings on the end of the hoses I installed on drain plug fittings of my transmissions. Now it is quick and easy to attach my drain pump to all 5 of these devices (the 2 trannies, the 2 mains and the generator)
