130 johnson prop suggestions

[basspirate]

i have a 20ft robalo center console with a 2000 johnson 130 on the back. i know the boat is slightly underpowered. right now i have the standard evinrude 15x17 3 blade aluminum prop. my wot is 4500 rpms. at wot i can get to 20 mph. i need a new prop cause i chipped mine. i plugged the numbers into a calculator and the calculator said i have a 50% slip. should i keep the same size prop or can i go up a few sizes to gain a little more on the top end. i dont do a lot of trolling and i know i cant get the boat up to 40 mph.

Re: 130 johnson prop suggestions

If you read the stickies at the top of the page and the helps on the prop store page
it will help you understand prop selection better. It is intirely possible you could reach 40.Your numbers are pretty screwy could be the damaged prop.
If you get it fixed and get back to us with some test numbers details of your boat etc we may be able to help.
