Oil drain hose

[jc turtle]

I watched a video on winterizing, and the boat they worked on had a hose that was pulled
out of the transom drain plug to drain the oil. I just bought a boat with a 5.7 1988 OMC.
The engine is out and apart, ready for me to rebuild it, so now would be a good time to add this hose.
Is this something worth adding? It looked pretty easy. The boat I have will be trailered only,
so changing the oil in the driveway will be on dry land, not on a mooring or dock.
Any thoughts on this? Does anyone already have this on their boat? Thank you for your input, John

Re: Oil drain hose

Your engine should already have the dipstick tube that goes to the drain plug in the pan if you still have the stock pan. All you have to do is thread an oil suction pump to the garden hose fitting on the top of the dipstick tube. Can't get much easier than that.

Dipstick tube #69 is connected to pan fitting #43.

Yes, I have this feature. It was well worth the time for me. I wish the filter drained into the pan, too. I can't remember exactly how I managed to match the threads. I used a 90 degree brass ball **** so I could reach the handle and also direct the hose as needed. Give yourself enough length to reach your collection pail. I keep the excess hose trained upward temporarily tie-wrapped to my fuel fill hose so that in the event the valve opens or leaks, I won't lose the engine oil into the bilge. - Grandad
