Has anyone come up with an idea(other than raising up and/or removal of the 100lb 4 stroke) for changing out the lower case oil on an outboard engine wet slipped boat? Yamaha requires the engine be vertical to drain oil (bummer). Top oil isn't an issue as I pump out fortunately. In the past I changed oil when dry hauling boat for other issues, but the engine is due and I'm trying to get around lifting engine up and off the boat...my luck it will go for a swim. , no shops on the water in my area, will take on a sailboat oil change...Thanks for any ideas.

I don't know if this will work on an OB, but on my Volvo outdrive this is how I did it. I went to hardware store and pick up two brass barbs that would screw into the fill hole at the top and the drain hole at the bottom, raised the motor, removed the plugs and screwed in the bards with 1/2" pieces of hose attached. Put the drain hose in a 5 gal. jug with lid and a hole for the hose. Attached a bicycle pump to the hose in the fill hole, lowered the motor to just above the water and pumped. It worked great. Forgot to mention I took her for a little spin before hand to heat up the oil in the lower unit when I was in upstate NY. In FL I would not have that problem so could pass up that step. Wish I had pictures, but I don't have that boat anymore either. Good Luck.

I guess if I had no other choice I'd isolate the bottom end by placing a 5 gallon (or so) bucket under it. You are going to be standing in shallow water or sitting in a dingy?
Good luck and let us know how you make out!

My only suggestion would be to locate some one down that way who has a trailer for a C 250 WB and rent it for half a day. I think you will have more of a problem getting the oil back into the lower unit than getting it out especially if the motor can not be taken out of the water fully and maintained in a vertical position.

Suzie,

I'd also check on the fine for any fouling of the waterways with oil, intentionally or not. I seem to remember $10,000 fine for such doings, though that figure probably would apply to massive fouling. STILLLLL

PS I can't imagine doing the lower case on the water. It's a pain in the lower unit doing it on the hard.

The 5 gal or even a trash can sounds like the way to go. Maybe even a 5 gal inside a trash can. Line it with oil aborbing cloths. Hope for the best. I just managed to change the top oil and filter (used a pumper out)- used two 12 x 18 oil absorbs under the filter.

Changing the oil/lube is on my spring pre-splash list, but for those who are in year round, how often do you think this maintenance action is put off or simply neglected, due to the difficulty of changing the oil and lube while the engine is on the boat?

My boat stays in the water year-round. I change the lower unit oil around Memorial Day and, depending on the engine hours, sometimes again about Labor Day.

The first time I also was kind of apprehensive about removing the engine from the bracket by myself even though mine is lighter. So I used a friend's hard dinghy, slipping one edge just under the skeg of the motor (which in the "up" position is just above the surface of the water) -- but got a bit of water in. Then used a regular car-type oil pan to catch the draining oil -- but the dinghy was not very stable and the oil pan didn't fit well in the bottom of the dinghy. Got the job done, but it wasn't easy and had to clean up the mess in the dinghy. The next time I recruited help removing the engine to change the oil on the dock (lean the engine against the dock box) -- it's infinitely easier this way. It also gave me enough confidence to do it myself.
