Re: Homemade oil draining idea

I like being able to see what comes out the very bottom...

so I use a hose in the drain plug hole like the one shown above. It will slide out through the drain hole in the transom, so I can just hang it out the back, take the cap off and let it drain into whatever. as far as oil filters... if easy to get to, do like anything else, if not, get a remote filter kit and hang it up where it's really easy to get to... imho...

I'm hard on stuff... and so I change my oil several times a season. I install a new high quality filter each time. I will run high quality oil - usually rotella T or others, for the first 50 hours or so and then switch to synthetic. mobile 1, redline or amsoil are the favorites. I have been running mobile one 20-50 lately. oil is a lot cheaper than engine rebuilds...

I also take the oil pressure off the front port in the block so you see what it is after the bearings... you can actualy see the idle pressure drop when the oil starts to lose it's viscosity. kinda scary...

Bubba says those who use synthetic and drain it early is throwing money down the drain. :p:p

I agree --- how does going down the freeway at 2000-rpm making 8-hp relate to cruising across water at 3000-rpm making 120-hp ?

Figure that out for me ?

That would take an hour meter, a calculator, and would make my head hurt :D

Re: Homemade oil draining idea

Hey waterbugs! New to the forum as well as boating.
I just bought a 2001 Crownline 205 BR with 5.0l Chevy and an Alpha I
outdrive. The first few days after I got the boat I looked at everything
up and down. I noticed a hose laying on the bottom of the bilge and the
bilge plug was attached to it with some cable. I thought "good idea, won't lose plug" As you all know, it takes
a good amount of yoga like positions to get a good look at anything in
the engine compartment. Therefore I didn't think anything of that hose.
Well today I did some more peering in the bilge and decided to see what the
hose was for. We here goes. One end is a 90 degree hydraulic fitting
screwed into the bottom of the oil pan and the other end is a npt fitting
(crimped on like hydraulic hoses both ends)with a square drive plug in the end.
The square drive appears to be 1/4 square and approx 1/4 high.
The previous owner drilled a hole crosswise through the drive part only.
Then attached a cable with a fishing swivel crimped on.
This is how it works.
1. unscrew the bilge plug
2. carefully pull on the plug/hose assembly and the hose will come out
of the bilge drain hole.
3. place pan underneath hose, unscrew the plug at the end of the
hose and wah lah.
If anyone is interested be sure the hose is smaller than the drain hole in the transom.
Although this idea might be a Crownline feature.

I left out a few details.
The brass bilge plug needs to have an attachment post on it. The cable needs to be about 6" long on the hose side with the swivel(allows for quick disconnect of the plug if needed). And a short piece if cable crimped on the plug end. What you do is stick the hose out of the bilge drain hole and attach the plug to the hose.
Then just shove it back in and screw the bilge plug in. This assemby can stay
on year round.

Hey how about some pics of that contraption for those of us bored enough to go make one for our boats!!

Thanks

Re: Homemade oil draining idea

ok all of the ideas work for each of you, just adding my 2cents here. When i change the oil at the end of the season i pump the oil out the dipstick(once it is started it continues until it loses suction) then after all the oil is out i remove the drain plug and run 2 quarts of cheap oil through and let it drain into an old coffee can to make sure everything gets flushed out through the drain plug. Then i remove the oil filter using a small garbage bag to catch any oil that might drip from the filter. Then i add oil and about a third of can of seafoam, run the engine a few minutes to make dure everything is sealed and the seafoam mixes with the oil, thus eliminating any moister that might still be in the engine and all is ready for the next year.

Good Luck to all and happy boating

A lot of overkill. Getting the last bit out is not really necessary if you are draining every year and if you use the hose that screws into the bottom of the pan, you would be getting everything out. I would also never ever put seafoam in an engine. Its not going to get rid of any moisture. Running the engine to operating temperature is what is going to get rid of the moisture. Stick to a quality oil and you will be fine.
