Hit your back button once and scroll to the top of the forum.The second thread from the top is called ------------ADULTs ONLY -------------------------No Exceptions-----

Click on that and scroll down to # 12. Click on that and Don S. has posted a link to an after market OMC manual...

Get a pump and suck it out thru the dipstick tube.

Re: Help please !!!!!!!!!!! 2.3 omc question

I recently bought a boat with an OMC Cobra 2.3 Liter Ford. There is no drain plug. Where the plug goes, there's a 90 deg connector for the flare nut on the dipstick tube to connect.

I removed the dipstick bracket retainer bolt near the upper end (9/16" socket), then loosened the dipstick tube flare nut with a 5/8" open end wrench (tried a flared fitting wrench, but it won't fit, too tight). The nut came loose easily and the oil started flowing as soon as the tube was lifted out.

I didn't try it, but the 90 deg. connector may rotate 180 deg so it points down and drain the oil into a pan placed in the bilge. On mine there is room. On other boats, may not enough room. (I was just verifying if there was any water in the oil pan (no, there wasn't) and not draining the oil, yet)

This looks like a fairly simple way to drain the oil, if a dipstick pump is not available.

Does this engine have the hose threads at the top of the dipstick tube? If so, buy a pump that connects there and suck it out.

Re: Help please !!!!!!!!!!! 2.3 omc question

I just use a 3/8 in. piece of clear hose hooked to a Jabsco pump that is mounted to the top of a 5 gallon bucket. The outlet of the pump is attached to a rigid pipe that goes all of the way to the bottom of the bucket so I can just reverse the pump, and pump the oil into the waste can. The 3/8 hose slides snuggly over the end of the tube.
The pump is 12v with leads I hook up to the boats battery.
