I wasn't aware you guys got any snow this winter.  

Unfortunately the cold temperatures didn’t bring much snow. But the M8 tires don’t like cold temps so still need the truck as a winter daily (or on WI spring days like yesterday). 

Alright before I start this is my first ski boat, I’m mechanically inclined but a lot of this is new to me coming from a pontoon. So two times now we’ve taken the boat out and I keep it in the lake on my pier. Cold it starts right up and runs literally perfect. First time out we were cruising around the lake at all speeds for around a hour until I went to take off and it bogged down and had zero power to where it was gonna kill it self. Any time I tried to accelerate it lost power and a few times it back fired. Limped it half way back and it died on me. Opened the hood and looked everything over and didn’t notice anything off. 10 minutes later it fired right up and back to running perfect. Second time same thing but stopped for food on the lake, came out and started right up but soon as there was load on it it died. Idles fine and I can even rev it up fine. Open the hood check everything out for 5 minutes and again try again and it’s perfect again. Any idea what this is before I just start buying stuff to replace til it’s fixed? I’m gonna check all filters and vents tonight. Thanks! 

OK, just did some more work....and let me start by saying...YOU GUYS ROCK!

I think I just fixed the problem. By doing the electrical testing I was able to see that the green wire had continuity to two of the poles, but the blue wire had none to any of them. I removed the screws and saw how the wires came in. Interesting that they are each connected a bit differently. The green wire was more direct. The blue wire went through a kind f bus, where a plate carries the current across to the other side. And there is a metal tab that comes out and connects to a tiny metal post. It was a loose connection there. I did a (pretty poor) soldering job to secure it. But then testing it at various points, and finally with the assembly back together and got continuity form each wire to two of the four poles. Put the rotor back in the housing, connected the battery, and BAM! she was running!

above it even looks like maybe there was overheating that caused some melting of the plastic?

soldered it....poorly, but it held.

So next step. I need to refill the pump chamber with hydraulic fluid? Not sure how full though. and then carefully reassemble. And then test.

Need a trailer for a 2020 Malibu 23 mxz around Austin Texas area or can travel. Let me know need one asap thanks! Also if you know anyone or any place selling one let me know!

thanks for the replies, definitely helps
