Yamaha Outboard Questions

[windknotnc]

1999 200hp 2 Stroke SW Series II carbed. Everything seems to be working fine but I have a few questions.

1. I have installed a new key switch and it appears to be doing what it is supposed to do but I was wondering if the buzzer should test buzz when I turn the key switch on? Most all engines I have had would do this.

2. I have an analog Yamaha tach that is working but I am not sure what is supposed to plug into it to operate the oil lights at the bottom of the tach. There are 3 sets of wires going into a plug. What feeds to this plug?

3. Using the override oil switch I pumped oil into the reservoir today before cranking it. Oil pump at the tank did its job. Is there an easy way to test this pump to ensure it will pump on it's own?

4. Is there a way to test the oil alarm buzzer?

5. On the starboard side of the engine, with the cowling removed, at the bottom next to the Main wiring harness plug there are two plugs. One has a green and a green w/red stripe on the plug. The other has 4 wires black, orange, pink, and grey. These are not connected, but the plugs match up. Are these duplicates for a different set up that my Main wiring harness is taking care of? I have an additional wiring harness with the opposite matched plugs on the end but have no idea where it would go.



I can provide pics if necessary of any components.

1. Yes.

2. On my '00 200 OX66s, there was a separate tach/oil harness in addition to the main 10-pin harness. This is what provided the signal for the trim and oil lights on my digital tachs.

Does the plug look like it would match up to this?

If so, you have the older style wiring and will probably need some adapters.

3. Do you have the oil tank harness installed? It runs from the boat mounted tank to the engine? Oh wait, if you were able to manually activate the pump via the switch, then the harness is there. Duh. My bad.

I would pull the little clear nipple off the bottom of the engine mounted tank and allow it to drain. Then reinstall and turn the key on. With no oil in that tank, you should get the buzzer and the pump should activate and start filling.

4. See no. 3. Or you should be able to pull the level sender out of the engine mounted oil tank. If so, the alarm should sound when the float drops.


I would get in touch with Andy at Shipyard Island Marina. He can tell you exactly what is needed to get you up and running.

Here's a bunch of pics I took of the rigging from one of my 200s...

Connections on back of digital tach.

Back of single key switch. I don't remember what was on the end of the wire that goes out of the picture.

Main 10-pin harness. The plug on the left is the engine end.

Trim/oil harness.

And I forgot there was another separate tach harness. I don't remember how it all got connected though. I want to say it ran from the key switch to the tach.

The oil tank harness was real simple. Square, blue plugs on each end I believe.

Remember that the ignition needs to be ON (motor off) to get the oil alarm when you pull the sender or float arm up out of the tank.

Thanks for the answers.

GW204--- My tach is analog with only 1 plug. It is like the small one on the back of your tach.
I do have 1/2 of the tach/trim harness you pictured. I think I know where the plugs go in the engine end (duh), but which wires and where do the attach to the tach. My tach works with the green lead from the 10 pin main harness. Would I substitute the green wire from the tach/trim harness in place of this lead?

It appears I have the older style wiring and will probably need some adapters or at least one adapter

I turned on the switch and pulled the float up out of the oil tank and I do not get any alarm. I can manually make the buzzer work by unplugging the pink lead from the main harness from the pink striped on the buzzer and grounding the pink striped wire from the buzzer to a ground. I know it works.

Yes oil does pump with the manual switch to the upper tank.


UPDATE

I have abandoned the Yamaha analog tach...I am not sure it working. I have hooked my new aftermarket analog tach up and it is registering perfectly. This all but solves the oil light tach/trim harness.

RESULTS
With the key switch on I pulled the float out of the remote tank but no buzzer goes off. When I drained the oil out of the engine oil tank the buzzer went off when the oil got to the bottom line.

The oil pump on the remote tank did not automatically come on when the oil level in the engine tank went down nor when the alarm went off; however, when I manually engaged the pump switch at the back of the engine oil would pump from the remote tank to the engine tank and automatically shut off at the top line.

QUESTIONS
1. What is the correct operation for this system?
2. Does something else trigger the remote tank pump to continually keep the oil at a certain level in the engine tank?
3. Should the buzzer alert me when the remote tank is near empty. (I noticed that the float only travels about 3/4" on the shaft)

Let me begin by saying I'm only pretty sure about these answers...

The float in the remote tank simply provides signal to the gauge so it display the proper level light, just like the float switch in your fuel tank. The float in the engine mounted tank is what activates both the alarm and the remote pump. The pump will not run all the time as it only has one speed and can fill the little tank faster than the motor can drain in.

Take a look at the follow thread on THT. There's some good info in it.

Specifically "The switch signals the oil-controller to turn on the yellow warning LCD on the tachometer, and to stop the transfer of oil to the outboards main tank" and "Starting in 1996, new electronics in the controller unit keep the pump from operating if the engine is not running".



Run premix until you are confident that the system is working properly. That is what I did when I repowered my Grady with the 200 OX66s. The only thing I noticed was a little more smoke at idle/trolling speed.

I have my Owner's Manual for same motor but '96 vintage - I'll see what it says about that. Hey, wait a minute, Yamaha allows you to download the manual for free from their website - go check it out!

I looked at the manual online and it answered the question about flow from the remote tank. In short the remote tank does not alarm, it only displays lights on the oil gauge, if you have a Yamaha tach and the appropriate harness to the motor. The remote tank only sends oil to the engine tank if the engine is running. All oil related audible alarms are generated from the engine tank float switch when it gets to the bottom line.

I took the boat to another marina with a good mechanic yesterday to have it checked out. I want to make sure the carbs and timing are adjusted correctly and that I have no electrical issues. Hopefully this Parker will be on the water early Friday morning chasing False Albacore.
