losing power

[roadking]

I have a 150 outboard. i took out the boat for the first time this weeknd run great at idle and at normal speeds. but when at wot.one minute it will run good but then it will lose power.if i slow down to half throttle and then increase to wot. sometimes it will go nice. i just got the boat and it had a full tank already.im thinking it may be bad gas.i now its at least 9 months old it has new cap roter plugs wires and carbs. can anybody help. thank you

Dirty carbs or fuel restictions in fuel lines and fittings are the most common problem to cause that. It could be an ignition problem but probably better to check fuel system first.

im reading other threads. do you think my problem might be a stator or trigger.

Yes it could be dropping a cylinder or the the high speed stator coil bad.
