OK I have a 2001 150 OX66 and my problem is that it is got to where it is very hard to crank and once it cranks it smokes like a train for just a minute or 2 then when you start to get on plane (3000 PRM) it will die but the motor keeps running. You can turn the key off and it will start right back up then do the same thing but after about 3 tries it gets on plane and will run 5000 plus RPM but it might run for 300 yard or 3 miles then it loses power again and if you turn the key off it starts right back and you start all over again. I have replaced all the filters and gas pump bulb and line but it still does it so can some one please help me out here.
