Kinda glad it needs some tweaks?
Thanks for bearings link. Got them and slowly moving forward.
Ready for your vid of success

Thank you! The vid might be awhile. Burnt up the starboard ESC on last nights test run, got some weeds wrapped around the starboard prop (and it's not even the bad part of the season for weeds, so mad). I ordered another ESC last night and a spare but they are the cheap china ESC's and take a few weeks to get. And then I go out of town for work the whole month of June.

So almost 5 months later.... I installed a new starboard ESC a few weeks ago. I ran it today and burnt up the starboard ESC again and I don't think I hit any weeds today!! The Port ESC is the one that runs the receiver, the starboard is just ESC, and motor, (power pin to RX is removed on the Starboard ESC). Pulled it out of the water and both motors and Port ESC were cool to the touch but starboard ESC was HOT!! and making funny beeping sounds. I only got one water pickup that splits into two and then into the ESC's and then the Motor's and each has its own exit. Both motors and shafts spin freely with no binding, props are 45mm ABC counter rotating (spinning in). The only thing I can think of is I don't have the Starboard prop spinning the right direction but I'm sure it is, (I can't test now with the one starboard ESC Burnt up). I don't think the boat would run as fast and strait as it does if I had the starboard motor spinning the wrong direction. Both runs I got about 5-8 minutes run time until the Starboard ESC burnt up. Please lets hear everyone's thought on this!!

I have never run a splitter because I know that water is lazy, it takes path of least resistance. I would run two dedicated water lines, and I bet your starboard power train chills out.

I was thinking the same thing but why would the starboard motor also be cool to the touch since it gets it's water after the ESC?? I'm going to look deeper into the starboard drive, maybe something is binding causing more load that the motor can handle but the ESC can't??

If you are still on 2s, you probably don’t have enough load to heat up the motor. And if you are driving around in a scale way, that would heat up the escs faster.

How about trying a blow test? Unplug the water lines just after the Y and blow on each... just to see if the starboard side has a blockage in the line. To me it is the simplest explanation... but we need some empirical evidence.

Jesse,
Yes still on 2S each side, I double checked both drives and found stuff that I needed to adjust in both (Starboard side was WAY to tight on the gear mesh). Ran it again yesterday and everything on both sides was cool after the run and I was running it at WOT for most of the time as in the first two runs. I will run it again hopefully in the next few days, hope it might be alright now. One thing I noticed is this is WAY too much power for this old boat but it is FUN!!! LOL!! At WOT it pretty much bounces violently from side to side to the point I would think it would roll over but it doesn't, it just keeps going. The props are counter rotating and spin in so I think it is weird that it does that. The only thing I can think is I need to adjust the drives to get the bow up higher because it must be hitting the chines on the hull and causing the side to side bouncing.
