Re: Props
Walleyehed's correct, the "standard" prop was the 12 pitch 3 blade. Although it's a complete guess, I would bet that it's the one you're looking for. Weight, size, and type of craft you have would help.<br /><br />You don't have many choices if you're looking for a new prop. There's the Michigan Match 3 blade that walleyehed gave you a link to, and also there's the OMC/BRP/Factory prop which is also three blade. There's not much difference between the two. They're avaialble in pitches from 9" to 14".<br /><br />In used props (ebay, etc) there's a little more choice. First you find the older OMC props which normally are 3 blade fractional inch pitch, like 12.5P. Some people get great performance from those, even though they're old tech and heavy. Second, you often run into Michigan Wheel speed props. These are often two-blade as that was 60s era speed prop technology. The bronze versions of these props should be avoided, since they're very hard on the gearcase due to their weight and the corrosion they cause in salt water. Since your outboard takes the same style of prop as the 50s 25, 30, and 35hp and the '60s 28, 33, and 40hp, there's tonnes of them out there.<br /><br />To be scientific about selecting the optimum prop, you need a tachometer and a reference prop like walleyehed said. But simply to get you fishing a good guess will do.<br /><br />I hope that helps!
