yamaha pro is right, but also check the cable and the selector knob. i had a cable brake at the selector, wasnt hard to find, and wasnt that bad to fix, just make sure you have the right movement on the cable at the valve, (which is a pain to get to or work on) i have two plugs that i use, just in case , when i am in a tourney. sorry about the boat warrenty, hopefully you wont need much, but the motor is different!!,, you get that warrantee regardless,, right?
