Re: 115 Yamaha alarm
I've got a 115 hp Yamaha that runs fine. I keep getting an audio alarm RANDOMLY!!! It's using oil from the tank & both heads are at 135-140 degrees.
Any ideas on isolating this issue?
For years I too had the same problem with my 1993 115TLRR... three different dealers w/o success. Then reading my Clymer Yamaha outboard shop manual, I found the following; although it speciffically states it's for the 1990 115 & 200 hp engines, it cured my issue!
"Yamaha has determined that there could be a problem with a loose main fuse within the holder on these models. If all 3 oil warning lights flash and the engine rpm reduction is activated, but there doesn't seem to be a problem, a loose main fuse within the holder may cause this false indication. These models are equipped with a loose battery cable warning system and this system can also be activated by a loose connection within the main fuse holder.
If this problem does occur, and the main fuse appears to be loose, remove the main fuse from the holder, carefully squeeze the fuse holder with a pair of pliers to tighten the contact on the fuse. Reinstall the fuse and restart the engine to make sure the problem has been solved. "
I do plan to replace the old "tube" style fuses with an updated spade fuse holder and fuses.
Hope this may be of use to you.
