MerCruiser/Chev block engine oil drain petcock

[Walter]

Hey folks...<br /><br />In regards to a small block Chev V-8 MerCruiser....has anyone ever heard of a reliable pet-**** drain that would replace the oil pan's drain plug? Changing my boat engine's oil is a bear because a drain pan won't fit in the bilge...well, it fits but only if turned sideways. That kinda defeats the purpose when trying to remove it full of oil while keeping the bilge clean!! A petcock would allow me to regulate & shut off the oil flow coming out of the oil pan. My thought is to utilize a smaller drain pan or even attach a hose to the pet-**** and run it out the boat drain hole. <br /><br />Walt

I used to use a drill pump in the dipstick hole. It werked great.<br />Mine came with a petcock,but still, I had the same problem you are having now.<br /><br /><br />But how about the hose trick? pump as much as you can out, then, remove the drain plug, and take it to the parts store. Get a petcock with the same threads, a 2foot length of hose to fit the petcock's spigot, and a hose clamp to clamp it on. The hose should be oil resistant. This way, you could attach the drill pump to the hose,open the petcock, and start drillin

Those drill pumps will work even better if you warm that engine up first.TRY IT ,YOU'LL LIKE IT.

Fellas...<br /><br />Garth, my Merc tech buddy loaned me his 12 volt oil pump set up. It worked ok except my dipstick tube has a very small inside diameter which I had to snake a 3/16" plastic tube down. Even with the oil warm it was like trying to suck a watermelon through a garden hose...very slow! Garth said some engines utilize a larger diameter dipstick tube...or one that apparently extends down inside the oil pan. He says his pump will evacuate the oil in just a couple minutes with that set up.<br /><br />I'll pester one of my buyers at work and see where we purchase the petcocks used on our bus engines. They may have just what I'm looking for...<br /><br />Thanks for the replies!<br /><br />Walt

Well, I took 12 footers advice and bought a drill powered pump. It worked like a champ! My buddies pump that I used before must be defective or something. Anyway, in less than 15 minutes I had the oil/filter changed and everything cleaned up and put away.<br /><br />12 Footer...I owe ya!<br /><br />Walt

Walter:<br /><br />In some boats, it is very hard to get drain pan in place let alone take out when full of oil. So when I change my oil I used a heavy duty trash bag... tape it in place, drain oil, seal, pull out, hang up to drain in recycle container for disposal!!! better than a drill & I get all old oil out of engine!!!<br /><br />No spills or grief!!!<br /><br />

Now we ARE disposing of used oil correctly, no sewer drains or back yards ? 1 earth, no refunds or exchanges.

MercilessMike:<br /><br />I hate to jump on someone else post but you hit a nerve... If you would read the whole message you would have seen "hang up to drain in recycle container for disposal!!!"<br /><br />I was at the recycle center yesterday... TWICE with my weekly recycling plus carried a friends stuff too.<br /><br />Just carried out my weekly garbage & didn't even fill up a garbage bag... What about you???<br /><br />Don't spout until you recycle all your stuff or take the time to sort through you "stinkin" garbage for the betterment of our enviroment!!!<br /><br />Good Day!!!<br /><br />

Fone_Man...<br /><br />It's funny you mentioned the trash bag idea. That was one option I considered. However, I was too paranoid that it would snag & tear on something thus spill oil everywhere so I didn't go that route. (Obviously I don't buy "Hefty" brand trash bags) The drill pump worked great but you're right...you can't get all the oil out of the pan with one. So, after I pumped out what I could, I placed a small drain pan in the bilge and drained the remainder.<br /><br />I'm still gonna pursue the pet-**** drain idea. I think that will be the easiest/cleanest solution yet.<br /><br />Walt

Walter:<br /><br />I have been doing this for years... I also double bag just in case I do grab rip or tear & sometimes bags leak from factory/out of box.<br /><br />This is why we have to clean out garbage cans every now & then!!! LOL<br /><br />Knock on wood... I have never had a problem!!!<br /><br />I have used this for other applications other than boating... great fexible drain pan right at your finger tips.<br /><br />

Walter:<br /><br /> I think this gizmo is what you want: ->https://ssl2.adhost.com/fumotovalve/static/products/oem.htm. Notice the hose nipple made especially for marine and industrial engines with poor oil drain access. I've handled those valves, they really work well and the check ball closure seals with no drips.<br /><br /> You might also check out the oil drain contraptions sold at www.griotsgarage.com, their hand-pumped oil extractor may be a better choice than the electric drill-powered pumps.<br /><br /> Hope this stuff helps.<br /><br /> - BSL

Re: MerCruiser/Chev block engine oil drain petcock

Just had an idea Walt... can you imagine how easy it would be to be using this valve when winterizing, etc... change oil & lower unit lube at same time... run drain hose out drain plug into pan under lower unit & do them both at the same time... while evrything is draining could be doing something else... isn't technology grand!!!! Let me know when you contact them in they have one for Chevrolet engines....<br /><br />
