A 525HP Murphy Moose on floats


The thing sounds like a dragster. Murphy makes great kits, is just a shame that it hasn't found his sweet spot
The cam lope actually reminds me a lot of the sound of a marine engine, like a Mercury 525 (Blue Motor) or Mercruiser 496. That Murphy Moose is awesome and would be a blast to pond hop with.

 
What a turd. The performance in that video is shockingly bad. I have a buddy with a Moose on floats that’s the best performing recip floatplane I’ve seen. This Moose is sucking hind tit.
 
Engine might dyno at 525...but burning 18gph he aint using it
 
The floats are too small. The CG is too far forward.

How can I tell? The tips of the floats keep dipping into the water. He even admits he needs ballast.

That'd do a lot to fix the anemic take off. Then again, I don't believe it's making the full 525hp.

Which engine does your friend have?

Performance looked pretty awful, I think a 172 with an 0300 on a hot day at gross weight would be off the water quicker.

TURD!
 
It had a Barrett souped-up Russian radial and Whirl Wind prop blades. I don’t recall the circumstances but it was totaled while parked.
Never had a radial, but I am not seeing a lot of downside in a Moose. The HP and GPH seem reasonable considering 540 alternatives. Rebuild costs do not seem particularly bad.

that moose was 20+ seconds to get off the water? Did seem slow for the amount of claimed power.
Maybe a lot of that power went straight into noise generation.
