See full version: How to Troubleshoot the Warning Module on a Mariner Engine
Turn the selector of a digital multimeter to the "diode test" or "continuity test" position, usually the last position on the right. Turn the multimeter on and touch the red multimeter probe to the tan-and-blue wire on the warning module horn and the black probe to the engine block, to test for continuity. If the circuit has continuity, that is, its resistance is less than 210 ohms, replace the ECM. here
The warning module of a Mariner outboard engine samples the engine temperature and oil level of the motor, the function of the engine overheating sensor, the ignition control module and the engine control module. Many of the operations conducted to troubleshoot the warning module are as simple as testing its reporting capabilities with a digital multimeter to ensure that they all work, and that there are no short or open circuits in the module. here
Suspect the engine overheating sensor is faulty if the engine is not overheating, but the overheating warning is operating continuously. Disconnect the sensor and turn the key switch "On." If the warning continues to operate, replace the ICM. Turn the key switch on. If the engine overheat warning does not activate when you turn the key switch to the "On" position, replace the sensor as well.
Ensure the boat's remote control is the one specified for the motor. You can find the information for the remote control unit for the motor in the operator's manual. more
Disconnect the tan and blue lead from the wiring harness at its terminal on the engine block and touch the lead to the engine block. Turn the key switch to the "on" position. If the warning horn does not sound, ensure that all leads between the warning module and the electronic control module are firmly connected. [links]

Re: 1995 Mercury 50HP- Oil Injection Pump Problem?
When the pump goes bad it results in not enough oil. To much the chances are very good that the rod number 27 has come unhooked or broken a end the rod runs between the pump and throttle linkage and adjusts the oil mix at differant RPMs. http://www.mercruiserparts.com/Show. =3373&bnbr=110&bdesc=Oil+Injection+Components more
The book would have adjustments and tests in it.
The very first thing I'd be doing when I went to get the boat would be to ask for the old pump back. Even though the dealer has put a new one in, you still own the old one. If he can't return the old pump, ask him why you should pay for a pump that he can't prove is new (by returning the old one to you). It didn't matter what we replaced in our shop, the owners got the old parts back, apart from engine and gear oil, they had to trust us on those.
I'd get a service manual and do it myself, or at least know what the mechanic is up to. [links]
The outdoorsman can never be too well prepared. Owning your own Mercury 90hp outboard repair manual is a smart move for more reason than one. Take steps now to avoid being stranded with no way back to shore.
Imagine for a moment that you have found the absolute perfect fishing hole in a large lake. The cooler is full and the time has come to head back to shore and enjoy your fresh dinner, but your boat motor will not crank. If you are lucky, you will either have incredible knowledge about outboard motor repair, or you will have a copy of a repair manual handy for reference.
Owning an outboard repair manual could be extremely beneficial for the fishermen who finds himself stranded on the water. Having access to quick troubleshooting advice, easy repair steps, and a guide for building an emergency kit to have with you on the boat might just save you a big headache one day. more
Access to both service and repair instructions for an outboard motor will also save a consumer lot of money in the long run. Outdoor hobbies like boating and fishing are not cheap, so saving money is a major bonus. Owning an outboard repair manual will allow the boater access to service the boat motor properly without the added expense of paying for labor. Think of all the fishing lures you could purchase with the extra money.
Of course, boat motors will also need replacement parts over time as general use requires maintenance. A repair manual can help you become your own mechanic by allowing you to do more sophisticated repairs on your own without an added trip to the shop. Knowing how to recognize signs for wear on your motor’s parts could save you from getting stranded on a lake in the first place.
Thumbing through the outboard repair manual can be helpful in building an emergency kit for unexpected boat repair on the water. Understanding the basic needs for common repairs made to an outboard boat motor gives a fisherman the ability to be prepared in the event that he has an unexpected issue. [links]
