I have a question has anyone experimented with different brand plugs? I have the NGK plugs in her now. If you use a different brand, which and did you notice a difference.
Also what is the correct part # for my motor, I am waiting for my service manual, I'll have it next week and I think the plugs in it now are not correct.
Also what is the correct gap for the correct plug? Thanks in advance......
Mine has a sticker in the lower cowl on the right side that says the plug and the gap.....dont know if my 200 would be the same as your 150 though

I believe it is NGK BR8HS gapped at 1mm (about .044").
I think my 150 took BR7's but I'm not positive and I think the gap is 35-39K. Stay with NGK.
