    Winterize Engine That Won't Start

    I'm working on a 7.4 mercruiser rebuild that hasn't started up yet. I've put the ear muffs on the outdrive to push water into it while turning it over. I think that means water has made it to the water pump and oil cooler and also the outdrive water passages. Since it hasn't run or had the...

    Assessing motor for rebuild or replacement

    The background: Made a really hard stop in the boat with too many people in the back which resulted in the engine starting to make a very quiet tapping noise.
