The props that i'am running are x637,x640,Prather 215. Is there a propshaft height i'am missing, whats a good starting point. One reason i want to get a handle on the 1440 series is i orderd a Villian S1.
I run a 1440 on my Villian 45 mph but that same prop won't work on my HTB mod boat, I guess stock motor an wood boat vereses mod motor an glass boat make some differences. We run a cut X442 an a 1640 we are tring a cut 1740 3 blade on our new OS motor.
