Axis Wakeboard Boat Forum

Crappy day yesterday, got the boat ready, went to the lake, dropped in it the water.. Making our way out of the five mile per hour zone and the dash starts beeping, and the display starts flashing "Engine Fault" and "Engine Temp".. Gauge was pinned in the hot zone so we limped back to the dock. Thankfully we hadn't gone to far, so hopefully no damage occurred. Pulled boat out of water and began looking around at things.. Water intake at the bottom of the boat was clear of debris. Engine was hot, but not as hot as I thought an overheating engine would be. No visable overheating red flags like cats changing color, etc..

Pulled the impeller and it looked fine. Looks just like my spare one that is brand new. Checked the valve in the boat were the water intake comes in the boat and it was not closed (thought maybe when I had my 20 hr service they maybe closed it? But no, it was open).. When we pulled the boat outta the water, there was a decent amount of water that drained from the exhaust, so that leads me to believe there was water in the exhaust system. About 12 ounces worth of water came out of impeller inspection plate when we removed that too..

Its going to the shop on Tuesday, but I am totally baffled as to what it could be. This boat has run like a top since the first time on the water. Never has given me any overheating issues or even warnings..
Its the 409 Indmar Monsoon.

I did add a FAE (fresh air exhaust) before it went in for servicing in January. But, when I spoke to the mechanic at the Axis dealer yesterday, he said they run the boat for like 30 minutes to warm it up after they change the oil, and if it had anything to do with the FAE, I would think it would have overheated for them.

The FAE is the only thing I have done, and the 20 hour service is all they did.. Otherwise, the boat has been in indoor storage.

Just wondering if anyone else has experienced anything like this..

Side Note: Just before it began to tell us it was overheating, there was a slight whining noise from the belt area that definitely was not normal or ever heard before.. I did fire the boat up once we dropped it in the water to make sure it started since it had been stored. It fired right up and so we tied it up and I left it idling for like 10 minutes while I parked the truck. The total run time the boat was on was maybe 20 minutes, and we never even went faster than idle speed since we were in five mile per hour zone.

A new "whining" noise could have indicated a failing bearing, possibly the water pump? Perhaps the bearing locked up and the impeller stopped turning. Could try taking the belt off (look and see if there are any signs of wear from being locked up) and check to see if you can spin the impeller. That might not explain why you still had water in the exhaust after taking if off though...

All I can do is speculate... Hope you get it sorted out quickly and get back on the water!

Is your boat a 2015? There is a service bulletin out for this on the new PCM engines.

Link to this? No issues so far but want to be aware of anything ahead of time.

No link. Called PCM for my 2015 t23. I get a service engine light. Throws a code exhaust manifold temperature. PCM told me there is a bulletin to flash the ecm. I can prevent the light by going slightly faster than normal idle while in the idle zone. I will get mine fixed at 20 hour service.

We had a similar issue yesterday. We were breaking in the new A22 and got the service engine light and "Service Required" on the display at around the 6 hour mark. I started it up and it was idling for about 30 seconds before it threw the warning. It ran fine up until that point, and only did it that one time. 7.5 hours on the boat now. I will have my dealer look into it at the 15-20 hour service.
