In looking through the owners manual on the Tohatsu 4 HP motor, it says "remove the water plug from the motor and screw in the flushing plug (hose adaptor)". I bought this motor used and it may not have the flushing plug included... What exactly is the water plug? See attached picture. Is it the rubber washer thing or the harder center piece. Can anyone with a Tohatsu outboard can give me any helpful hints.

Honda wanted $50 for one
...so I bought one of those rubber ear-muff things that attach to the hose and go over the water intake. I figure the attachment is threaded to fit the engine and attaches to the hose. It would be nicer to have because the ear-muff attachment that I have sprays water in a few directions. Here are a couple of pictures, the second showing the spray that I mentioned: http://www.boatsnbits.co.uk/acatalog/Engine_Accessories.html http://www.theeagle.com/sports/outdoors/112504williams.php ...RickM...

Nissan
I just bought a new Nissan (same as Tohatsu) 9.8 4-stroke. I was reading the maunuel (it hasn't been in the water yet) last night. They made mention of the flush connections on the motor. They also said the prop must be removed before flushing, although I don't know why? I was sort of hoping I misread it as removing the prop to flush seems like a pain in the prop!

It's probably a lawyer thing.
Like keeping your hands out from under a running lawn mower. With the prop off, it's harder to get hurt when flushing with the engine running.

Flushing
Jeff, I have this exact motor. There is a nut, shown in your picture, that is second one up from the bottom. Use a 3/8" (I think) box end wrench to remove it. You have to get a screw-in from a dealer. Attach a plastic hose to the insert and a female end garden hose coupling to the other end. Then, you can flush your motor with a garden hose. Do this every time you use the motor to flush out salt, etc. John Richard s/v Jack's Place

followup question
See the attached image for my followup question about which nut to remove to attach flushing adaptor. I will need to contact a dealer to actually get the flushing adaptor. Perhaps if I saw the adaptor, it would answer my questions. Also, would it be adequate to simply attach an "earmuff" type hose clamp to the bottom of the engine and flush it that way? Or is the upper hose attachment considered to be better?

I think your questions have already been answered. The attachment is surely a female garden host treaded piece on one end (just like a nossle or sprinkler has to attach to garden hoses) and it's threaded on the other end to go into the second hole from the bottom on your picture. The earmuffs work fine. See the second link I sent previously for a picture of one. It goes over the water intake so the engine can suck the water in the bottom. When in place and the water turned on, you then run the engine, and you have to make sure that a nice steady stream of water is squirting out the little check hole higher up somewhere, the same as it does when the engine is in the water. An alternative is to get a large bucket, fill it with water and put the hose into the bucket to continually keep the bucket filled while the engine is running. I don't have a bucket large enough so I got the earmuffs. I would have bought the flush connector if it was $10 instead of $50 (more like $60 even), but the earmuffs are OK. Water is going to go all over the driveway anyway. ...RickM...

And with those earmuffs,
be sure that when you are inside the dingy after starting the engine and yelling to your wife to turn on the water,,,,that you check the 'muffs.
Yep, she turned it on all right. Full force! The 'muff blew off. By the time I noticed, the water pump was ruined.
