Having same issue. After running  for a little bit, the gas gauge shows zero the depth gauge shows zero the wedge stops working and the surf gate stops working. Did anyone find out the issue of why this happens?

Hi

Lots of steam from under the dash, hot water is going into bilge. How do I stop the flow to the heat exchanger under the dash? Where is it fed from?

Many thanks 

Most issues I have experienced with noticable differences between set speed and actual speed were caused by high engine load and high boat trim (the amount of weight and the distribution of it in the boat).  Testing for this problem can be done by checking for differences between set speed and actual speed when the boat is run with a very light load and again while the boat is using full ballast weight and the wedge.  The issue often occurs when a larger pitch standard prop or speed prop is used on a boat with too much weight.  The solution would be using a lower pitch high altitude torque prop. 

The recommended HA torque prop for the 2024 Axis T220 with the M5DI engine is Malibu PN 3541919, OJ 1919 Wake Pro V4 15"x13".  Loads caused by using full ballast, the wedge, and large crew/equipment weight may be too high for the standard Acme 2249 prop or the Acme 2277 speed prop on your boat in the conditions you are using it.

I'm on a river, but it has very little currwnt/wind to affect speed. My 2020 t22 I never had this issue 

Does any one run the gx tower down cover on there M220? Or any similar sized boat with gx tower and the tower down cover. Just looking to see what you think of the fit and how well it is against water pooling when left outside in the rain.  Cover will be used only when in slip not for trailering. If you have any pictures that woudl help too.
