Axis Wakeboard Boat Forum

I have a 2015 Axis A22. PCM Monsoon 350 Engine. Just started getting the Service Engine message and the MIL light comes on, then throttle goes to limp mode. Ran the diagnostics and the error codes showed that both Exhaust Manifolds are overheating. Both were at about 220F. Engine temp was fine at about 160. Replaced the impeller but still happens. Checked the hoses and no obvious leaks or clogs. No obvious leak at manifolds/risers. Mechanic said the ECM was up to date. I’m at a loss. Any thoughts or recommendations would be greatly appreciated!

My 17 409 is doing the same thing. We are waiting on PCM to tell us what to do. We all know the manifolds need replaced, but they are dragging their feet to let dealer go forward. Still testing for water flow.
