Which prop is best?

I am new to boating. I have a Avon Typhoon s4.6 with a 25 hp Yamaha outboard. I use the boat to scuba dive from and as such need to move heavy loads. I am not concerned about how fast the boat will go. Does anyone have suggestions for a good prop for such a setup. Currently it has a 9 7/8 x 10 1/2-F prop on it. This one is beat up and I am looking to replace it.
Thanks

Check Yamaha sites to find the range of props they recommend for that motor, then try to guess which might be best for your application. I had a Zodiac MkIIC with a 25 OMC on it. Of the recommended props I tried a 10X15, which was OK when just me in the boat but bogged down when loaded with dive buddy and gear. 10X13 was best compromise for me. You might be able to up to the next pitch since your prop seems to be a little small.
Do you play harmonica? We had a great player up here who went by your name.

I play harp but nothing like the real King Biscuit Boy, Richard Newell. He was fantastic.

Yes he was. Did you know that Ronnie Hawkins gave him that name?

I didn't know that. The King Biscuit Time radio show which began in the early forties in still on the air today.
