So I am new to the boating lifestyle and I recently bought a 91 four winns 190 freedom with the 4.3l OMC Cobra I/OB. I believe I have all the kinks worked out as far as the engine, but the problem now is I can't figure out why the trim gauge and fuel gauge isn't working. The fuel gauge worked fine when I purchased the boat but now it just shows full all of the time. I'm thinking it could possibly be the float in the tank. Also, I'm trying to figure out exactly where to start researching on the trim gauge. I eventually want to replace all of the gauges and dash panel in the boat, but for now I would be content with having the gauges operational. Any help would be greatly appreciated.
