I have a '97 Bayliner Capri with a 3 liter mercruiser/alpha one. Just bought it and took it out last week. The unit ran for the first couple of hours as we got to know the boat. We pulled each other on a tube for an hour or so with no problems. After making a few sharp turns the motor would start to run real rough, the first few times it would clear up on its own. It started getting worse, where the motor would die completly. We could re-start it only by holding the throttle wide open until it started. We came to the conclusion that water must be in the tank and when we made the tight turns it would stir it up enough to get pulled into the system. We trailered the boat, tilted it as far back as possible by using the trailer tongue jack on blocks, removed the fuel gauge sensor and siphoned the remaining fuel from the tank. We put some fuel stabilizer in and refilled the tank. Well to make a long story short...the problem stayed the same. The only way the motor will start is at WOT. Bottom line is, the fuel pours into the carb. as soon as the engine cranks. We took it to "a guy" that does boats. He installed a kit on the carb. and it did the same thing, dumped fuel. He then put on a carb. that was on a boat that was working ok and it did the same thing, dumped fuel. Now he says that the fuel pump is putting out too much pressure and needs to be replaced. Here is my dilema...#1-This is the original pump the boat came with and worked the week before we bought the boat, #2-it worked fine for a few hours on the water the day after, #3-I have never seen a pump gain pressure during its life. Is this possible or is this guy just guessing? Does this sound like a valve and seat issue? Will an automotive type fuel pump be safe to use? They seem to be quite less expensive is why was asking. 49.99 vs. 140.00
