    Humminbird down imaging problem

    I just installed my new depth finder combo with di, and am having trouble. While trolling in 10-15 feet of water, the unit registered 700 ft! I lowered the frequency output, and this fixed the problem, except that the down imaging wouldn't work at all! All I get is a solid blue line on the...

    OMC cooling question

    I just purchased an almost mint condition 1971 Johnson Sea Horse 6hp. It had not been used in 15 years according to the guy selling it. I drained the old gas from the tank, put in some fresh fuel and it cranked on the 4th pull!! Idles well, no leaks anywhere, I am tickled pink. The water pump...

I want to make sure the oil injection is adjusted right, but I haven't been able to find a diagram and...

    No Electric power

    I bought a 2003 Sea Chaser yesterday with a 90 Mercury 2-stroke. The only "problem" with the boat is that the fuel gauge wouldn't work. So, I got home, popped the gauge out and started testing wires. I must have arc'd a wire somewhere because now the ignition, starter, and trim aren't getting...
