I have a very vague
recollection of something similar happening on a 115hp Optimax that we were running on a dory. I think
, and my memory is v. hazy on this
, that it means that your 2 stroke tank has got to a low enough level that the engine/gauges decide that you are now into the reserve. At a guess, a litre or so remaining? It then counts down as a percentage to 0%, when I guess you've truly run out! If the oil tank is full, then double check that the float switch/sender isn't stuck, and then if it is still happening, ask the dealer! I think that we also had some trouble with an smaller internal oil tank within the o/b housing itself, that we needed to bleed to make sure that there was no air in it. That also set off the oil reserve alarm,
in fact the smaller tank may have been the reserve itself! Might be worth a look, but I would ask the dealer. There must be loads of people in the forum with Optimax units, so I'd be surprised if nobody knew what was going on. Hope someone can help.
