Well I guess I stired up a can of worms here. Factory reccomendation is 50:1 and I probably go 32:1 on the bigger engines but not on the 4 hp. Also trying to figure out what RPM is needed to hole a 4 hp block. Hell guys we just ran the shoot out down here with a 28' cat with 2.5's on it at trap speed 108 and top speed GPS at 112 turning 8500 rpm on only Merc premium plus oil at 40:1 surly a 4 hp could handle 50:1
