Welp, broke something. Axis t22
Boats overheating, cleaned strainers in oil coolers and sea strainer, replaced impeller which was beat but not shredded, pulled and tested thermostat in boiling water which opened (that thermostat housing design SUCKS by the way).
Boat climbs to 210 and holds when idling. As soon as you give it throttle it will climb and alarm. Happened suddenly when wake boarding the other night, no warning, just 20 minutes of riding and bam.
I’m thinking either something is up with thermostats, but it opened in boiling water.
Next step is to check circulator pump and to verify it is not air locked and fill the system with freshwater from there. If that doesn’t work we will replace thermostat, anything beyond and we are back to the dealer for warranty repair...
Any other tests I can do at the dock? I really don’t want to lose weeks of summer at the dealer if it’s something I can fix myself.
Anyone have these problems before?
