For a better balance of speed, run time, and heat, the x642 is a great propeller.Aquacraft Revolt 30, Aquacraft Lucas Oil Cat

I have tried an x645 on my stock Lucas Oil (well, stock electronics, blueprinted bottom and rounded rudder bottom) and it was fast, but watch the run times and temperature. The motor got quite warm - 45 mm diameter is a lot of blade to swing. But it went like a banshee!

I can't give an honest answer because I haven't tried an m445. I'd like to try one though, because it seems like a good prop for these boats; a lot of people run them. I can say to not try a Grimracer 42x66 lifter prop on the Lucas/MC - it would barely get on plane! That prop worked well on my Revolt however.Aquacraft Revolt 30, Aquacraft Lucas Oil Cat

My favorite for that boat is the Octura X642 and then the Grimracer 42x55. I have an M445, but never tried it on the Lucas Oil.
My boat with a 2030kv UL-1 motor, will do 53mph tops on the X642, and about 50 mph with the 42x55. The X642 is a great prop for that boat.
I don't see any cooling differences, the boat comes out with 115F on the motor and 110 on the ESC with stock cooling.Comment

There are a few warnings however with this setup....
- The hull isn't designed for a hard flip at that speed. Make sure to adjust your strut down to help prevent blowovers, move your batteries further forward as well.
- Solder 5.5mm connectors to the motor and ESC wires. The 2030kv motor runs hotter on the wires than the 1800kv motor does, it will melt your 4mm solder off easily.
- Don't get lazy with taping up of the hatch. Make sure you tape up well, at higher speeds you risk your hatch flying off in a flip.
- I am already assuming you are using a Kintec or OSE flexshaft, the factory one barely could handle stock motor and plastic prop.
- Your run times will be reduced from about 4 minutes to 3.5 minutes with the higher kv motor.Comment

I have both the MC and LO, as others above mentioned the GR 42x55 is a great all around prop. I also have the m445 and have changed each boat to it, picking up a 1mph to 3mph. I havent tried the x642 yet but still have the 1800kv stock motor in both hulls.
With this setup, these boats are my fun, "never a problem", run 4 minutes each batt set and my kids drive them too.
On a side note, I accidentally picked up 2 revolts(bought one here on OSE, won another on ebay) and those boats are a blast too!

I raced my lucas oil in P-limited offshore this weekend and compleated 13 3/4 laps in 4 minutes using a M445.Comment

M445 is starting to push it for offshore with that boat. IME I have had good luck in sprint racing with a M545 and a thinned x440/3 for offshore. 1800kv in both(Won our club class in sprint, only ran in offshore a couple times but that prop definitely didn't lack speed against the other boats). Whoever mentioned 2030kv and x440/3 for offshore I would say you can easily cook a motor with that setup if it is warm outside.Comment
