Retro-fitting Mercruiser Quik drain oil system.

My boat sits on a trailer. Not sure if you do the same? I installed a couple brass fittings into oil pan (with a 90 degree bend) with a good brass shutoff valve, along with a barbed fitting,along with a piece of tubing with another barbed fitting and plug. Just have to jack the trailer up after warmup, stick hose out of boat drain plug at bottom transom and wait about 1/2 hour. Slow, but gets every last bit of oil out of the engine. I guess if you are at a slip and in the water, this would not help you. Could you not do what I just said and hook some sort of drill pump to the lower drain plug hose if you were to plumb it that way with boat sitting in water? Most guys add some sort of plumbing to the bottom drain plug on pan. best of luck, Tom
 
Warm the engine prior to the oil/filter change.
Purchase yourself a Tempo Oil Boy for extracting the nice warm, lessor viscosity oil.
The kit comes with an array of tubes and a rubber hose adapter fitting.
No electric motor, no wires to connect, no spark issues, narrow profile, easy to stand up-right in the engine bay!
Just pump the vacuum up..... sit back and let it work.
Quick........ Easy...... Done!

You will not regret owning this extractor... it offers many uses!
Start a fuel siphon....., purge a fuel system of air......, extract water....., purge a closed cooling system when changing anti-freeze, etc.

I have no association with Tempo..... I just happen to really like this extractor system.
 
I just bought the same extractor from West Marine a couple weeks ago on sale for $59.95 works great just put the tube on or in pump it up and do something else while it sucks the oil out. Small tip I learned from a mechanic if you have an upright top mounted oil filter poke a hole in the top and it will drain the oil out no mess when you change it.
 
Yes, you will end up using the Oil Boy for several things. Great tool! :D

The correct cartridge for an inverted filter should have a back-flow flapper within it.
The inverted filters also prevent pre-filling of the cartridge.
If you can swing this around, or replace it with a conventionally positioned cartridge, you'll be better off, IMO.
 
if you warm up the engine the oil extraction systems via the dip stick work pretty good, most times the "quick oil drain system" is more trouble than its worth including the adapter piece between it and the engine rusts out causing an oil leak and you have to pull the engine to fix it.

I installed a Merc. drain kit on my 4.3L--all brass hose ends and connector. Need a little ventilation in the bilge?
