I have a Phoenix 920 with a Yamaha 250 SHO. The motor has been flashed. I am currently running a 26P Yamaha T2 prop. I just purchased a Razor 4 XL on the props for sale board that I want to try. My question is about the vent holes on the Razor prop. I have had three boats in the last 20 years and they have all had Yamaha motors that ran Yamaha props. None of these props have been vented.
The Razor from what I can tell since I haven't received it yet has 8 vent holes with 4 of them currently plugged. Will I need to plug all of the vent holes? If so I will need to order some plugs as the prop is only coming with 4 plugs. Are all vent holes the same diameter or are there different sizes? I just want to make sure I have everything I need on hand when I test the prop this weekend. Any help would be appreciated.
