The oil level indicator light on my 1987 Yamaha 70-HP two-cycle outboard is acting up. It's one of the three lights on my tachometer. The oil tank under the cowling is full but my add oil light (yellow) is on. Does the this light just monitor the oil level or does it let you know if the oil is getting to the engine? I think it its just a level sensor because I made it back to the ramp and the engine was running perfect. Any help is appreciated. Thanks, Garey

Check the wiring on the back of the gauge and at the engine. It could be either a loose connection or a faulty sensor on the oil reservoir. A shop/service manual will help you on the wiring.

You may want to check the condition of the in-oil-tank filter, presuming your oil tank is similar to mine. I have a 1991 Yamaha 90-HP. On my motor the filter, which has a very fine-mesh, was coated with some substance which was stopping the oil passing through. Opinions on this site was that the substance was probably oil residue which built up over the years.

It's a simple, though messy, job to replace the filter.

Thanks for the suggestions. I'm going to run by where I keep my boat tonight and check the electrical connections and see what is necessary to remove and clean the tank. I guess the oil light on the tachometer monitors more than just the level. The weird thing is I haven't heard any alarms or gone in to safe mode. That leads me to believe it may be just a clogged or restricted oil line. Thanks, Garey
