Sunday July 4th left the dock from Meinke's at 6:00 AM sharp headed out to the Gravel Pit. While on plane traveling at 25 mph, at approx .5 miles out motor bogged down and shut off, started back up and tried to proceed, bogged again. Emptied the fuel/water separator (on it's 2nd season) there was a lot of debris, started back up and headed back in to Lorraine's Landing, changed filters and headed back out, motor bogged two more times, I decided to call it a day. On the way in the motor bogged 3 more times, on the 3rd time it wouldn't start back up, had to call Boat US for a tow back in. On Saturday July 4, I was out at the Gravel Pit 5.5 miles out, and finished by 12:30, came in at 30 mph without an an issue, no bogging. missing or vibration, can anyone with past/similar experience offer any assistance?
