I have jsut experienced my second changing of the engine oil. Either the manufactureer made some engineering/design mistake of I am not doing it correctly. I have to seaarch for the dip stick from the rear of the engine. Having consiiderbale difficulty in finding the port hole to extract the oil using a oil pump. Suggestions willd be appreciated. Thanks Bill Millon e-mail: mll12@hargray.com

That's right, thru the dipstick...

and it's no fun. My H37C did not have the access door from the aft cabin that was in later models. And there is a heat exchanger blocking access to the dipstick, it cannot be seen only felt. And then only when you know exactly where to feel. But that's what you have to do. Buy a "good" pump, the kind that includes the container, not the electric drill model. And you do not need a motor. Insert the tube to the bottom and pump away. Should get at least five quarts, probably seven. Move the tube occasionally to be sure it is all the way down. Be careful that it is not pressed flat against the bottom of the oil pan which will block it. Ed(schencked@bfusa.com)

Oil Change in 33.5

Bill, The engine oil change on the Yanmar 2GM20F on the Hunter 33.5 is on the starboard side. It is accessed thru the small access panel next to icebox.The oilextraction and fill are thru the same tube. The Dipstick at the rear of the engine is the transmission oil. The transmision oil full mark is near the bottom of that dipstick and it generally should not be over filled, which is easy to do. I use a Topsider vacuum hand pumped portable tank to extract the oil (both engine & transmission). You have to wiggle the suction hose around and toward the aft end to try to get all of the old oil out. Good luck, Dick Carey S/V Puffin

It's a bear.

Bill: I assume that you have a 3GMF engine. This is basically the same engine that we have on our H'31 (2GMF). I have no idea why they did not put a small mount on the block so you could at least feel the hole. Ours is basically out of site, so you need to feel around to get the tube in the hole or to replace the dip stick. I have thought about trying to use something like a dremmel tool to put a score on the block so it would be easier to find. Any of the geniuses out there that have solved this problem, we would like to hear from you. Otherwise maybe someone can design something that would make our lives easier.

Hint

Make sure that the exit hose on whatever pump your using does not pop out of whatever container you are putting the old oil in, as I know from personal experience that getting sprayed all over with old engine oil does not enhance your oil changing experience.

Make sure it's hot & try using a mirror

Bill: On my 87H285, I have access only to the front & port side of the Yanmar 2GM20F. The oil dipstick is on the starboard, of course. So I use an inexpensive dime-store mirror (about 5x8) which I simply prop against the engine compartment wall, and aided by a portable flourescent 12V light, have no trouble finding the dipstick hole. The reverse cues take some getting used to. The other secret to a successful oil change is to make sure the oil is hot. Otherwise, it takes much longer to pump or suction out.
