Get a 6 gal tank and hose and hook directly to the fuel filter inlet on the mtr. This by-passes the boat fuel system. If it works you have boat probs. If not you have mtr probs.

also try pumping the bulb and see if that helps. I would get a brand new fuel line to use with the test tank mentioned by the boob.

I also have a 93 fast strike 150 with similar problem... would die at wot. I had my dad pump the fuel primer bulb as we went to wot several times without flaw. If he stopped pumping, it would die out. I pulled the pump and it would not pass the test outlined in the manual...was leaking air around the pulse inlet (housing). I am ordering a new pump today...hope this helps!
