Soldered up my batterys and esc with 6mm bullets. My first 6s run will hopefully be this weekend in my otherwise stock Pro Marine MTR.
What did you do to your boat today?

Snuck out of work today a few hours early to get some work done before Sunday morning's run. I Sold my Blackjack to REDLINE1 last year and have missed it ever since. His is running so well on the new motor that I bought a Miss Geico to run with him. I shortened the motor wires, soldered on larger bullet connectors, cut the stuffing tube back, and installed a Wohlt wire drive along with an OSE upgraded strut. I need to drill out some of the cooling inlets/outlets, caulk the 90* elbows on the water jacket, and plumb new cooling lines. I plan on just copying my old setup which was good enough for 76mph in REDLINE's boat the first time out, and then tune form there depending on conditions at the lake.

The Geico ran good today, but I got everything squared away except for the ESC. It didn't dawn on me until the third set of batteries that the ESC was set for 3S and I was running 6S. Got it corrected, but by then, the water had gotten pretty rough and I wasn't able to hold it wide open for very long. Had fun and the boat came back in one piece.Last edited by fweasel; 09-30-2017, 07:23 PM.Vac-U-Tug Jr (13mph)Comment

The motor in my Geico was running fine last weekend on the first few runs as long as the boat was moving, temps were int he low 120's on pretty aggressive props. However, the motor would heat soak and the temps spiked quickly as soon as the boat slowed down or stopped. I had an ESC programming issue, so who knows what that was adding in terms of stress, but things will definitely better better after today's project.
I scribed a rectangular patch on the bottom of the last ride pad and then drilled out the four corners with a small bit on my Dremel. I then switched to a small mill bit and opened up the entire hole. Filed it square with a hand file until the water pickup snapped into place. The leading edge sat a little proud of the bottom of the hull so I ran the pick-up across a file laid flat on the work bench until it was flush. Mocked it up in place one last time and JB Welded it into position.

I needed to add a second water outlet and knew I couldn't handle seeing two different kinds of hardware, so they had to match. I had a matching set, but the existing outlet was epoxied in place and wouldn't come out. Went hunting and found the same outlet on my Voracity. Pulled that one, drilled a new hole, and installed. Matching, nice. Hopefully the JB Weld is dry by tomorrow morning and I can test it out at the lake.

Finally got around to removing the motor with the broken shaft out of one of my Sports hydros so repairs to the hull can begin.
She was speared through the belly by the sponson of another boat in a racing incident. The force snapped the motor shaft, mangled the flex cable, & bent the motor mount. Not to mention the gaping wound in the belly.
You can still see the broken shaft in the coupler.See the danger. THEN DO IT ANYWAY!!!
