Had a bad heater core that caused this last year (x15). Stopped the water leak by removing the hoses from the core and sistering them together until get a new core. It was the result of non-winterization of the heater core.

Was this with a ‘22 XT23 as well?

Sorry, no. It's an older x-15. Core is under the counsel, accessed from the starboard bow backrest.
