    Backfire through carb

    I have had a problem with my 94 Mercruiser 4.3 liter 205 HP since last year. The problem is an intermittent pop through the carb, then right back to running smooth and strong.

    seawater in cylinders

    Just got back from a 3 1/2 hour, one engine ride in 3 to 5 footers, fun! 2 trips ago, while in rough water, I had one engine become hydro locked and was unable to turn it over until removing the plugs and blowing out the naughty H2O. After getting a look at the risers and seeing their condition...
