2006 mercury outboard opti max 200 engine alarm, (4 beeps). oil was run low, do i need to prime the system or should it prime itself?

Better to replace the float and switch.

Engine tank should be plumb full tight. The engine supplies about 2 lbs pressure through one of the 2 lines going to the boat tank. The other line takes the oil to the engine tank. If that line gets kinked or pinched, the engine tank won't get oil, a check valve lets a little air into it, and the oil pump keeps getting oil. When it goes down just a little, the alarm goes off telling you something is wrong.

Sludge in the boat tank could plug up the pickup screen. I've also seen them plugged up by a foil oil bottle seal carelessly dropped into the tank.

Once you find out why the oil couldn't get there, start the engine with the cowl off and loosen the cap on the engine oil tank until it leaks, then tighten it down and clean up the mess. That tank is normally plumb full tight.

If when the engine is running, you crack the cap on the boat tank, you should hear pressure let off. If the cap leaks, it won't build up pressure. If there is pressure, the oil line is plugged or kinked.

If pressure isn't supplied, the problem would be the crankcase check valve on the engine, lower forward starboard side, with the hose going to it.

hope it helps

the alarm will be a safety max rpm alarm
if you are doing 5000rpm then you night consider a different pitch propeller as the engine is well outside the peak performance for power and economy

good idea to remove the alarm rather than fixing the fault
after all you could run out of oil , ruin the motor completely because of the lack of oil and have a long swim home
fix the error in the alarm / sensor and be safe

There is only a few cars fitted with an ancient petrol injection system that needed any priming.

Diesel engines mostly need the injection system priming but petrol injection systems do not.

Lots of cars use a system where the fuel pump runs for a couple of seconds when the ignition is switched on and that is all the time it takes to prime the fuel system. After a couple of seconds the fuel pump switches off and waits to restart when the engine is cranked.

As priming the system takes only a couple of seconds some manufacturers don't bother with the brief priming run of the pump and just have the pump start when cranking.

Could be faulty supply, fuse, pump relay or the pump itself.
If the car is fitted with an immobiliser, perhaps that is the problem.

Regular maintenance is needed for oil changes. If your oil level is dropping you need to keep it up to operating level but you do need to find out why it is burning or losing oil. If your oil is black then it needs to be changed regardless of the miles on it.

oil pressure sensor is shorted out needs replaced..

You have to prime the oil pump using a special tool... it goes down the distributer hole yes, you have to remove it.. make sure you mark it carefully!!!!!!!!!..

Low Engine Oil Pressure

The oil light is signaling low oil pressure in the engine's lubrication system. You say that you have checked the oil level in the engine and it is ok.

The oil pressure needs to be checked with an oil pressure gauge. (It is most unlikely that the warning light is faulty).

Should the oil pressure prove to be low - as I expect it will - the cause needs to be investigated. It is likely that there is a malfunctioning or failed oil pump or the oil pressure relief valve is sticking in the fully open position.

Failure to change the engine oil, at least at intervals stated by the manufacturer, will result in severe oil degradation and reduced oil pressure. However this is usually not enough to trigger an oil pressure warning light.
If you have changed the engine oil in the last six months or so, and have not done over about 7000 miles since then, oil degradation should not be contributing to the low pressure problem.

If the oil pressure gauge check confirms low oil pressure I suspect, on further investigation, that you will find a problem with the engine's oil pump.

You will need to get your vehicle to a reputable auto service shop to have the oil pressure checked and the problem investigated. Do not drive the car in this condition (except to get it to the repairer). The engine is not receiving sufficient lubrication and you run the risk of expensive engine damage and total engine failure.

Hope all goes well with it. Cheers.

Sounds like a security system warning, must use scanner to accesss system. Hope this helps.
