- Merc 8.1 Mag 375 HP / Bravo III,4 blade prop. 28mph at 3200rpm.
I cant wait till I repower with a 496ci in my boat.
I am leaning toward a Volvo duoprop package.
The twins are for people who like to have an extra engine to work on. :smt101
Or is it a spare engine used for ballast, and a emergency backup engine :huh:
The 5.0 engine has like 300ft lbs of tq at 3600rpm?
The 8.1 engine has like 509 ft lbs of tq at 3200rpm.
From what I have read.
A duo prop will get you another 3 mph cruise speed over a single prop.
If you are buying new.
Take a look at the Volvo Package.
Stronger drive and better impeller and fwc setup.
The blocks are the same.
