    I'm porting the reed block cages. I'm not sure this will prove to be a good idea. What do you think?

    Did you use lock tite? I'm always worried the screws will come out and go through the motor.

    Update: My motor runs really good. It’s the best idling motor I’ve ever owned. I’m seeing speeds close to 50mph on my Edge 553 duck boat.

    I found out later that the 60 carbs have about the same bore as the stock Tohatsu 50 carbs. The 70 Yamaha carbs have a good bit larger bore.
