I have twin Yamaha 300's. I think 2013 model years. My Speed Fuel gauge is giving the wrong readings. When I start the engine, sometimes it says I'm doing 31MPH and getting 4.6 GPM (I wish). Speed does go up as the boat is moving, but it's never accurate. Sometimes it is accurate. I've cleared the pitot tubes in both engines (stuck a small drill bit in each, twisted and pushed in until I felt resistance) and the issues persists. It was intermittent, but now it seems it's showing the wrong values most of the time. No other issues with the engines or the boat in general. Any ideas?
