Yamaha 200 salt series II

[Aquaman]

I just purchased a boat with a Yamaha 200 salt series II (the survey checked all and said it was good).

Once in the water, the dag-gam thing would not go beyond 2400 rpm's?!?!? When I tilt the motor out of the water it goes up.

I accidently pulled the chock and the motor jumped to 3200 rpm for a couple of seconds I am buffled and

Someone suggested it was the oil pump and the way the motor was acting is an automatic safety precaution!?!?

Any ideas out there?!?!? and how much would repairing this problem be ?!?!?

Thanks

It could be just low oil. Real quick, go out and check the oil reservoir and see if there is any oil. It has an auto shutdown to low rpms. if oil is low. Add oil and see if you hear the pump running it to the engine sump.

I went out and checked. It's full of oil.

Make sure the shift/throttle linkage has got the full range of motion. I've seen cases where the throttle position was not fully extended even though the throttle lever at the helm is all the way full.

Normally a low oil problem would be indicated by an alarm accompanied by the low rpms so I doubt that is the problem.

It might also have a bad power pack and only half the cylinders are firing. Did the marine surveyor water test the boat?

[Aquaman]

I dont know if they did conduct an on water test. But the results of the compression were:
136-135-131
141-136-136
I checked, and the throttle is not the problem.

You can have perfect compression in all the cylinders with a bad power pack. It prevents the plugs from firing and will bog the boat down when it is under load. On the trailer the motor will run like a scalded dog.

I have a Yam 150 and got real familiar with the oil system with the exact symtoms you describe a few months ago. The oil systems are basically the same on all Yam models, at least from the 115 up. Before you rule out oil as the problem, check the engine tank on the port side, to see if it is also full. If that tank becomes low and calls for oil from the main tank and none is delivered, the CDI will retard throttle useage, such as you have described. The throttle restriction also comes into play with the cooling system alarm. Posibly you have a stuck thermostat, or other water restriction. If you have digital instruments you should have got either a flashing light for an oil system or a cooling system failure, if either is the problem. If it not a oil or cooling problem, it could be, as Tom said, a throttle position sensor or a crank postion sensor, of which I know nothing about troubleshooting either, other than what it says in my factory service manual (mid 90's).
From the research I have done, Yamaha CDI's seldom fails, but it does happen. If you find you need to check the CDI, I have one for a 200, you are welcome to use for that purpose. To remove and replace the CDI is a 30 minute job. You don't want to just buy one and see. A new one for my 150 (1993 carbed) is $537.00, and I think for a more recent model 200, somewhere around $800.00.
A good source of troubleshooting is iboats.com. Go there and register and do a search of alarm problems, and if you can't find some help that way, ask a question. A master tech from Kittyhawk,NC, by the handle of Rodbolt, is undoubtable one of the most educated and experienced participates there. Also, IBoats.com has about the best prices I have found on parts, if you need to order something.

Good luck with it.

Aquaman, definitely do as qoutrage said and check the reservoir on the motor. The oil tank on the boat should have a pump mounted on the side of it that pumps oil back to that reservoir where it is then fed to the motor. If that pump goes bad, you could still have oil in the tank on the boat, while the reservoir on the motor could go empty.

There is a low level switch on the reservoir that will limit RPM's on the motor, but if low oil is sensed you should get a very annoying and constant alarm. Normally when you first crank the motor, do you hear a series of beeps? If so, then the alarm is probably functional--mine uses the same buzzer. I'm also pretty sure that if your RPM is limited due this problem that that motor will cut out or run very rough if you continue to open the throttle past what is required to achieve the RPM limit. Also, if it runs right when you tilt the motor up it is probably because the level of oil in the reservoir shifts forward and satisfies the switch--I have definitely seen this happen before.

You probably should check the fuel filters too. You may not be getting the gas to it.
