Merc 200hp on a 1974 Tsunami 20' - Propping Performace

[drtyTshrt]

I have been told that the Mirage Plus and props in likeness are to big from the 2.4 Mercs.
These prop were designed for the 2.5 and opitimax motors.

The diameter and weight is the difference.

The Enertia Eco is supposed to be a good choice in a newer style,but these motors need a 13.5 dia. prop.

I have a 1989 200 with a worn out no named prop(I mean razor sharp and less than the original13.5 dia) and on a 1998 20ft SF and I turn 6500-6800 at 48mhp.

I want to try the Eco or find an older 13.75 in a 19p or 21p.
