After just a very satisfying year with the twin 300R's on my Marlin 350 FS (35' deep V Center console, non stepped Hull, engines sit at 27" c-c, current top speed 52.8knots (fine tuned toe, trim & props turning out, Bravo1 20" FS) ,cruise 35-37knots)...
I am buying a new Ranger 621fs pro, looking to power it with the new 400R v10, does anyone know if there will be a big difference with this motor compared to the standard 400 Verado v10, thx.
Since Mercury has litigated all of the aftermarket tuning manufacturers from selling modifying software options for their engines, will Mercury be developing its own type of tuning software that could be sold to the Customer?
