IVO had issues with not staying torqued. If I remember it was for the 4 banger Lyc and maybe the Cont too. I have one off my O-235 Smith Miniplane that's a wall hanger now. I would talk to Daryl at Warp Drive first. I have a 60" 2 blade WD on my Corvair and found it to be no advantage over the wood Sensenich I took off. No worse but no advantage other than I can play with pitch angles. The AM13 is only turning at 2250 so it may be worth it to explore a 3 blade. I wonder why they geared it that way and did not go with a 2.1 ratio that would have your turning around 2800. Is that an option when you order the engine? Anyway, Daryl will point you in the right direction.
