I have a Regal 2100 with the Penta engine. Each year, I get this light when starting up and it goes away. In some cases, this light comes back and usually its related to old gas so I put treatment in like Heet, additives etc.. and this normally goes away. However this year, this light keeps coming back intermittently. The boat runs great without any issues it seems when the light doesn't come on so I am stumped as to what may be causing this issue. Any insight? The serial is # is ISKA42.
