We maintain several 450R powered boats. Singles and multi-engines. This includes a charter fishing boat with over 2500 hours on a quad set and no major issues. None of the others (20+) in our care are experiencing any problems.
Skater30: Why don’t you tell us the name of the dealer who is having so many problems with 450s? I’d avoid them like the plague.

Anyways I'd say speed difference is boat dependent.
And they claim the 450's have more torque down low.

Hi,
My Phantom 25 runs 88-89 mph with the 400R. With the same type prop (Max5) I expext 95 mph with the 450R. With a CNC 5bl cleaver, maybe a 2-4 mph more. Plus better accelleration
I learned back in 2011 when I bought my Verado 350 Sci that its imperative that the rigging of this type of engine is done by the book. If not you can run into all kind of issues.

Mine will run in some sort of protection mode that doesn’t trigger an alarm if they are started on low battery voltage. A normal user might have a heck of a time diagnosing that.
*not verados , was making a statement about fuel injected 4s OBs in general
