He's running a gen 2.Red Ripper are you running the 1st or 2nd gen.
The owner's manual states "In case of engine trouble, all three warning lights flash at the same time". I would take it in to a local authorized Tohatsu mechanic. Find a mechanic here: http://www.tohatsu.com/dealersearch/index.html Also depending on your serial #, it may be eligible for an upgrade to the air injectors (just had mine replaced) see here: http://www.tohatsu.com/tech_info/injectorcampaign.htmlHas anyone ever had the oil, water temp, and the battery light flashing at the same time with a tohatsu. I might not be having a prob. With the prop it might be something with the motor. For the first few months of owning the rig everything was fine and I am just noticing the drop in Rpms
