Prop for a 9.5 1967 Johnson Outboard

[bb52]

I'm confused as to what pitch prop I should get for my 1967 9.5 horsie Johnson outboard.<br /><br />The model # of the engine is MQ-13B and my current prop has damage so I know I'm not getting the full performance out of it.<br /><br />I have a 1965 14 ft. Monach V-hull fishing boat and mostly stay in rivers and lakes. Although sometimes the river I go in can get kind of rough (and what fun it is to boat in it!! )<br /><br />I used the prop finder and there's a variety of different pitches and I'm just about clueless. I want to be able to get the most speed out of the engine.<br /><br />Any help would be appriciated. <br /><br />Thanks..

I have this exact motor with a 8x7 prop that pushes my 12' alum jon boat (2 adults, gear, tm, battery, 3 gal gas) 12 mph gps. What size is the current prop (should be stamped next to the hub)?It has a very dependable motor. Best $250 I ever spent on a motor.

It's 8 1/2 by 8..<br /><br />Would there be something better to use?

I owned a 1967 Johnson 9 1/2. Bought it new for $380.00. I would use a 8 1/4 X 8 1/2. These numbers are on the original prop that came with the motor.<br /><br />I used the motor on a similar boat and it had very good performance.<br /><br />If you really want to know the best prop for your set up, you need a tachometer. Then you may end up testing different props. Don't know if it's all that important to you because most just use the standard supplied prop that comes with the motor.
