I was out surfing last weekend when my boat overheated. Ran for about 30 min before we lost power and shut the engine off. Blew the lid off the coolant reservoir. My raw water pump is working because I can see water running through my strainer. Had to get a tow in to prevent any damage. Dealer says it is the thermostat. Anyone else with a similar issue on the raptor 400? Roughly 270hrs.

Boat ran fine the weekend before but we never ran it hard because there was still ice on the lake.
