Propeller Selection

In the chart below you will find a
propeller selection list. This chart will
enable you to select the best propeller
for initial setup of your Saito ™ engine.
Figure 5
You will note a letter (A, B,C, etc.) stamped on the top of the motor mount. This letter identifies
the production version of your engine. Should you ever need to order a part or have a question
pertaining to your engine, specify this letter along with the engine type. This will allow for
easier identification of your engine.
