I had posted earlier about problems i was having with my 06 V-max 150 (carbed). Between 4000 and 5800 rpm, it would lose power and pick back up. Bottom end was normal, very strong. It was driving me nuts. I had changed 10 micron filter, fuel pumps and primer bulb. It still did it. I winterized my boat saturday and figured during the winter I would change all the fuel lines out. I pulled the fuel line off the port tank and unscrewed the 90 deg fitting out of the top of the tank, the suction hose inside the tank had a 1/2 inch split in it. Primer bulb primes up right now. Hopefully problem solved. won't be able to find out until spring
