How to change oil with a rusted dipstick?

[jonny rotten]

Mercruiser 4.3
Dipstick rusted though real low down by the engine. I have carpet walls on the sides of the engine which makes seeing and getting your hand in their nearly impossible ( horrible design). I would have tried make a coupler with a rubber hose and hose clamps but I don't see that being an option due to where it rusted though.

There is no way I can get to the drain plug in the pan and would not risk taking out anyway not knowing if if would go back without issues (older boat)

I'm reading pulling the motor is the easiest option to replacing the dipstick that I REALLY don't want to do just for an oil change

Any other way I can get the oil out?
Ideas?

Boat type and some picture will help get some suggestions and answers. We have no idea what you are dealing with...

The dipstick tube in a Chevy engine is easy to replace if you can get to it.

As far as changing oil. It has to go through that dip stick if not out the drain plug. 3/16" nicopp brake line would pass through the dipstick tube very easy and allow you to access the bottom of the pan

remove the sections of boat between you and the motor. usually a few screws

replace the dipstick

Order a new tube and stick... typically 1 10mm bolt or 3/8... pretty straight forward and simple

depends entirely on the vintage. the dipstick could be pressed into the block

I have a relatively cheap vacuum suction unit that came with a plastic tube long enough and small enough to slide into the dipstick tube.

I would try to fix that dipstick problem.

Are you sure you can't drain it from the oil pan drain plug?

You may or may not have this setup....
My oil pan doesn't have a drain plug per se. It has a rubber tube attached to the oil pan. It lays in the bilge and has a plug on the end. The tube gets pulled out through the garbard drain hole, out the back of the boat. The original brass garbard drain plug had a cable attached between it and the hose for easy retrieval.

That being said, it's much easier to suck the oil out of the dipstick tube, but it's nice to have another option.
