We experienced no water coming out of engine. Mech replaced water pump and wheel with blades bent. We were running at full speed and engine shut down. Was able to get back to Marina. Took to mechanic and he replaced fuel separator and file filter in engine. Checked gas in boat and was fine. Took it back out and did same thing at full speed but could not get it started again. No warning alarm and full of oil. Your comments are appreciated.
