B3 with 4/3 blades . Vs 3/3 blades
Posted: Wed Oct 21, 2020 3:30 pm
Got back into boating, My old boat was a 20’ Crownline with 350mag on a 3/3 blade B3 set up (60+mph)
My new (to me) boat is a bit of a special. 2016 R5 with 520 B3XR drive. However the props are 4 blade/3 blade (26P)
Have read that merc uses the 4 blade to help lower HP boats plain quicker.
Being this is a 520 wouldn’t the 3/3 blade set up a better option? (Comparable Volvo DP are 3/3 blades).
Know cobalt is a heavy boat, however during wet test was only seeing ~62mph on gps
Is it me or did mercury racing miss out on this set up?
If so what 3/3 prop set up should one be looking at?
