Change prop or change drive gear ratio?

[Coz]

Finally figured out why one engine runs slower than the other. Turns out the drives are geared different. 2.0 vs 2.2. The 2.0 runs 10% slower

Can I change props to correct this or do I need to have drive regeared?

Hate to say it, I would re-gear the drive, so everything stays in balance.

A prop change "may" find the sweet spot (I doubt it), but your torque out put will not be the same between the 2. Torque and output speed change with ratio changes.

I have the same issue.

New to me 2005 Rinker Fiesta Vee 360 was stock from facoty 496 Mags Bravo 3 with 2.0 Ratio drives.
So here is my issue just checked my drive ratio while servicing my drives port drive 2 turn to one on output (2:1) while the starboard is 2.2 turns to 1 (2.2:1) It has a metal tag that states 2:1
WOT Port 4566rpm Starboard 4895rpm 39MPH
Cruise Port 4194 rpm Starboard 4217 rpm 34 MPH Port engine throttle advanced more apx 300 rpm
Did stall test both engines apx 2000rpm in gear starboard wot easily reached 4500rpm port barely made 3800rpm
I was starting to check port engine for lack of power but this ecplains the 400 rpm loss at WOT

Looking for thoughts run it, repitch props to gear rpm back on port engine, Running stock props change ratio
