1962 16-footer with Mercury 60 Command Thrust

Postby Simon86 » Tue Mar 30, 2021 3:49 pm

Hello--Excuse my English. I am Swiss and I speak French. I translate with Google. My name is Simon.

I restored a classic 1962 16-footer with tiller. I need help choosing a propeller for a Mercury 60-Command Thrust 2.33. I already have done research on the forum, but I find a lot of info on the Yamaha 70 but nothing on the Mercury 60 Command Thrust (60 CT).

Are these Yamaha propeller sizes good for the 60 CT?

  • 13.25x14 PowerTech SCP
  • 13.25x14 Yamaha Performance Series
  • 13.25x14 Turbo 1
  • 13x17 Yamaha Painted Stainless Steel

I know that I could not install the Yamaha on the Mercury.

Are the Yamaha propellers the same sizes as the Mercury BlackMax propellers?


Thank you all for your help.

Bon Jour, Simon. Bien Venue a continuouswave.com.

The Mercury 60 Command Thrust has a 2.33:1 gear ratio.
Le Mercury 60 Command Thrust a un rapport de démultiplication de 2,33:1.

The Yamaha F70 has the same gear ratio, but more horsepower.
La Yamaha F70 a le même rapport de démultiplication, mais plus de puissance.

On that basis, a propeller recommended for the F70 may have too high a pitch for the Command Thrust 60.
Sur cette base, une hélice recommandée pour le F70 peut avoir un pas trop élevé pour le Command Thrust 60.

The BlackMax propellers from Mercury use the FLO-TORQ hub. They will fit the propeller shaft of your Mercury engine.
Les hélices BlackMax de Mercury utilisent le moyeu FLO-TORQ. Ils s'adapteront à l'arbre d'hélice de votre moteur Mercury.

Simon -

Look for these sizes

13.25x15 PowerTech SCP
13.25x15 Yamaha Performance Series
13.25x15 Turbo 1
13x17 Yamaha Painted Stainless Steel

This is the results from the prop size calculator.
