Prop for Suzuki DF 140

[kirt123]

I have a Suzuki DF140. I have a 21P powertech and would like to experiment with a few higher pitch props. Do any Merc props fit these also? As long as it has the came gearcase size and spline count, can you use any prop?

You may be able to tell by comparing some props right here in the iboats prop store. Have you read the stickies at the top of the page?
What boat,what is your present rpm and speed?What would you like to accomplish?

Re: Prop for Suzuki DF 140

My current RPM is 6200, current speed is 48, and I have lots of hole shot. I wanted a bit more speed. I went to this motor from a 135 opti and lost about 3-4 mph. I could not exactly tell if any would work but it looked like some lower HP Merc props might fit it. Basically my main question is just what other props fit it. I can choose the right props spec once I try a few. I was thinking of trying a hustler prop but it says to add 2 inches on my prop for OEM replacement, so I assume that means I need a 25 not a 23?

Is 6,200 the max rated rpm?
As I understand it the powertech is a satainless prop when you change materials you introduce more unknown variables.The Hustler is a great aluminum prop but I would stick with a stainless and if powertech has what you need stick with powertech for more predictable results.
For simplicity of checking fit I looked up Hustler props for Merc and Suze.
No match that I could find I thought maybe it would be the same prop
diff hub but both were different.Of course I could have missed gearcase size or something.

Re: Prop for Suzuki DF 140

Kirt, your motor is turning the correct RPM and your prop slip is at 7% which is very good. You can find a better prop , but it will require much testing and some money for a gain of probably a maximum of 3 to 4 MPH, if it worth that to you try it. You might check to see if the motor is raised high enough on the transom for maximum performance, but other than that you are extremely close to your maximum performance.
