Thanks volvodspec. Cleared up some stuff I missed. €350 a prop though! More than my car cost.

I'll just follow your check list and see how it goes!

the clamps aren't that much of a problem with 340 props, the rubber bushes damp the peak forces in the torqueline. on the 360's couplings it's all solid; bolts can overstretch and the connection fails.

i've shredded the rubber coupling on mine, turbo power eh
