    what thermostat

    I have a 1989 3.0 Mercruiser with an Alpha I outdrive. The temp. guage never moves and the engine is only warm to the touch. What degree thermostat do I need? Will an automotive type work? I only run in a lake with a neutral PH. The engine runs fine, do I really need a thermostat?

    Hit a rock.....Oh, Sh#%@

    After years of good luck, it finally happened. I hit a boulder with my 17 foot runabout with an alpha I sterndrive. Very scrary experience that I wish on no one, It trashed the prop & broke the skeg. Question, will a skeg guard be a suitable fix and does anyone have an opinion about a comprop...

    Mercruiser ran w/o water!

    I test ran my(with earmuffs) 1989 3.0 mercruiser i/o for about 2 minutes before noticing that the garden hose was crimped and the motor was dry! I immedietly corrected the water flow and after a little bit of steam everything appeared normal. Question, should this cause any concerns?
