Which prop should i use?

[bassone]

I have a 15' alumacraft superhawk cs 1994 model with a 30hp yahama it needs a new prop the one on there is 9.75" 13p should i stay with that or use a different prop, just bought the boat so i have no idea how it run with this prop. the prop is missing a blade so i can't try it. i would like the best performance i can get from it. Thanks

Re: Which prop should i use?

You shouldn't make a prop change without a tach to check the results.
Based on some very limited research it appears the 13" is a little too much.
If you stay with the 13 and it proves too much you shouldn't use it.If you go with the 12 and it proves to be too little you can still use it and just watch the rpm.It will have better hole shot and push a load better.
