No oil alarm

[moodyscruz]

I have a 200 Johnson 93' and the oil alarm keeps going off, it seams that it's not getting enough oil, the tank is full, is there a way to adjust the amount of oil that come out of the oil injection system?

There is a very simple test didcribed in the service manual.

Re: No oil alarm

As he said, there's a simple test described in the service manual. An even simpler test is to mark the tank and calculate how much oil is actually being used per gallon of gas.

If you're at all unsure, you should be running pre-mix.

If your alarm is the "no oil" alarm (vs. the low oil), in my limited experience, it might be caused by something as simple as a minor air leak in the oil system. You can check and/or replace hoses and clamps (use the ratchet clamps, not metal hose clamps or zip ties), reprime the system and see if that helps.

I had intermittent no oil alarms that would always be immediately solved by 1-2 pumps on the oil primer bulb. I don't know what the exact problem was, but I went through and checked and re-attached all the ratchet clamps and it seemed to solve the problem. During this time, it was burning oil at a normal rate too (I tend to constantly monitor -at least roughly - oil consumption by marking my oil tank with 1 qt. lines and just watching to make sure it goes down throughout the day, and then checking the burn rate when I fill my gas and oil tanks).

Re: No oil alarm

Thanks for the reply's. I did mark the tank and the oil is going down, but not as fast as I think is should. When they put the tank in the battery compartment they kind of twisted the hose to make it fit, so it's getting oil but I'm not sure if it's enough. I didn't get a service manual being I bought the motor used and they had to put this oil injection system in. The old motor had the system removed. I could remove it and premix it again but I kind of like the idea of just keeping the tank full.. I do have a clymer manual but I don't know if it's in about the oil injection.. I'll redo the hose to make a straighter line and try to keep track of how much oil I'm using. Thanks again

There's no need to guess or be unsure. Just fill the oil tank to a mark (any mark). Fill the gas tank full. Run the boat at cruise and WOT (not idle or trolling) until you burn at decent amount of gas, say at least 5 to 15 (the more the better) gallons of gas. Re-fill the oil to the mark and fuel to full, keeping track of the amount used.

Most accurate is to convert both oil and gasoline to ounces or at least pints (1 gal = 8 pints or 128 ounces). Convert your oil used to the same units. Then divide the amount of gas used by the amount of oil used (pints of gas / pints of oil). This should come to around 50-60 (in other words 50 to 60:1) in a normal VRO/OMS system regardless of the version, if you're running at cruising or WOT speeds. Post your numbers if you're unsure if it's the correct burn rate.

For example, if you burn about 5-6 gallons, you should burn about 2/3 to 1 pint. If you burn 10-12 gallons, you should burn approximately 1.5 to 2 pints. That's about all the accuracy you need to know you're in the right oil burning rate.

If you're doing a lot of slow speed (no wake, trolling, etc.) your oil consumption will likely be much less, so that's why I recommend cruising or WOT speeds.
