RE: IMAC Prop Selection????
Tom,
I'm using a 29x12 Mejlik<sp> 3-blade on a 42lb Jtec with the same exhaust setup. Nice and quiet and still more than enough power for the uplines with 2 snaps. I suspect that once I get another 5 gallons through it I'll be changing out to a 30x12 3-blade as I can rip the 29x12 if the air is cool enough and I'm only 7 gallons into the engine
A good 30x13 2 blade works fine but you can rip that one pretty good
