Oilchange methods

Ron,

Follow your dipstick tube. If it goes into the side of the engine then removing the drain plug will remove more oil. However, if the dipstick tube runs along the outside of the engine to a small metal block on the bottom of the oil pan then using one of the vacuum pumps will remove every bit of oil from the engine.

Thanks, I'll take a look next time. I don't recall it being on the outside though.
 
On a marine engine or a marinized car engine like MerC, Volvo etc, the dipstick tube is a special one designed to get to the bottom of the oil pan so the oil can be sucked out. There oughta be a Yammie expert out there who could confirm this for an O/B. Neighbor has a 225 Yammie and bought a Harbor Fright "Oil Boy" knockoff and uses that. But I don't know if that's best practice or not.
I, too, have that cheap HF sucker. Looks like a 2-1/2-gallon gas can with a bicycle pump on one of its caps. Stupid cheap soft plastic hose was useless. I run a short piece of fuel line from the changer to the dipstick and it gets all four quarts out of the Chevy V8 in literally seconds. At least well under a minute! And doesn't spill a drop. Getting past stringers and engine mounts to change the filter is another, often messy, matter...
 
Two or three years ago I bought a Jabsco Model 17850-1012 from boatfix. I cannot seem to find it on th Boatfix site now, but I am sure it can be obtained.

This is a Jabsco pump mounted on a three gallon bucket. Goes in through the dipstick tube. A little slow when lifting the oil 3 ft. but seems to do a good job.
