I bought a new Mercury 135 V6 which is just about run in now (done 8/9 hours but still on 50:1 mix fuel). Runs great no problems at all - until we try to pull a skier. The engine just dies at 2000 revs. this remains the case (even without skier) until we swap to the spare fuel tank - and the engine runs fine again.<br /><br />We thought originally that it was a fuel tank/line blockage as swapping the lines seemed to solve the problem.. until the problem occured on the spare tank too.<br /><br />Can anyone throw some light on the matter???<br /><br />Thanks in advance,<br />Mark
