I recently purchased a new ride with a 2014 30hp Tohatsu 4 stroke. I love the motor. Runs smooth and quiet, quick, efficient, etc. Ran the boat Monday and all was well. But, when I threw on the earmuffs to run it on the garden hose, not a drop of water from the, for lack of a better term, pee hole. Now, I'm told the water pump impeller is no more than 10 months old. So, I don't know whether the impeller has suddenly given up, or there is something clogging a water passage. I can't get anyone to look at it before Tuesday and I'm not particularly versed in the way of outboards, diesel engines are my usual frustration. So, any suggestions on how to check for or clear a clog or something simple that I'm overlooking would be greatly appreciated as I'd rather not spend the holiday weekend on the trailer.
