I have a '97 Maxum SC 2300 which had been running perfect until we imprudently went into a narrow channel and got stuck in shallow, algae bottom water. I raised the outdrive and slowly pulled out although the engine kept stalling. Finallly, we found deeper water and although the engine hesitated a couple of times, we were able to get back to the boat lift without problems after cruising for about half an hour.

I figure all was good again, but the next day the engine started but after 5 minutes stalled and would turn over but would not start again. We were close enough to the boat lift at the house to get back with paddles (we face Sarasota Bay in Longboat Key, FL). I waited until the next day and tried to start the engine; it did cough and wheeze and started briefly, but that's it. The gas gauge showed less than a quarter tank, and I put in two more gallons in case the reading was inaccurate. But no help. The batteries, spark plugs, and the sea water fuel separator are six months old (or about 10 hrs cruising). As noted above, the engine was running fine before this episode at the canal. I am the original owner and the boat is serviced regularly by trained mechanics.

I did not notice the temperature gauge on the cruise back from the narrow canal, and did not go far enough the next day for the engine to overheat even if the strainer was clogged.

I wonder if I need to put more gas in the tank. I was told to first check the gas pick up; how do I do that; is it inside the tank? Also to check the antisyphon valve; again where is it in a Maxum. Anything else to check to make sure that gas is flowing into the carburator. I intend to call a mechanic, but would like to be informed to understand what he might tell me.

Your thoughts will be appreciated. Many thanks for taking the time to read this.
