My first post here..:
Last year I had the engine report some error code 28's, shift pos sensor. I had the dealer take a look at it but of course the sensor worked 100% perfectly when the mech tested it.
Now also have gotten the code 49.
The engine (a 03 F115) is operated in cold water, usually around 40F. I heard at a different dealer that some F115's were prone to over-cooling in cold water , and replacing the thermostat to one from a F100 would help in those cases. Anyone else heard of this?

Engine warning indicator sequence?
Hi All,
I have a problem that I need advice on. My engine is Yamaha F115 AETL from 2002
Yesterday I noticed for the first time the engine indicator starting blinking on my Yamaha gauge. The sequence is 2 / 8 and sometimes 4 / 9. I looked through the service manual but it only referenced some manual diagnostic test (with an external lamp attached to engine) I noticed the warning in rough sea when I was trimming the engine, other than that the engine runs fine.
Does anyone know what that particular sequence means and is there any online chart or manual that clarify indicator codes?
Thank you all, Joe

The code 28 is incorrect shift position switch and code 49 is ignition timing is being slightly corrected(when starting a cold engine). This is for the motors sold here in USA and not sure if would be the same for your motor but probably is. The codes are listed in service manual but I only have manuals for USA models.
