considering one of these on a boat i am looking at. what can you tell me about these. How do they stack up to the 250 pro xs on speed, fuel consumtion, hole shot, and dependability? I heard a tale that if i do buy one of these and I have to have warranty work, that when i bring it make sure its got a BRP prop on it or they will not cover is this true? What kind of oil will i have to burn in it and how much does it cost? I usually use pennzoil premium plus and have for years and love it so will i have to change? thanks for your input just trying to get educated before jumping back to the blue side!
