First start off by saying I changed my water pump impeller almost a year and a half ago. Last two or three times out have been fishing in some fairly stained and shallow water. I was headed down the lake this past saturday and motor shut off. No alarm or anything. Checked battery cables and they were ok (came loose last week). Cranked up and went on no problem kept speed down. Overheat alarm came on and I shut her down. Looked back and pee hole and nothing. Didn't run her for the rest of the day. When I got home hooked up the ear muffs and flushed her for a good 10 minutes and then tried to crank her and no alarm and with a minute or two of idling and a little throttle, water started flowing. Obviuously I am going to drop the lower and check out the water pump. Is it likely I just had trash in the line clogging it? Any suggestions on anything else I should check? Thanks.
