    BR9ES

    My local shop was out of BR8ES-11 plugs so they said the BR9ES plugs are the same plug just liek a half a heat temp. different and with runniing premix and a higher compression head that it may actually run better. Any thoughts?

    They may foul alot sooner (especially running premix)- you would have to keep a close eye on it.

    hmmmm.....didnt think about that. Im having the worst time getting my carbs adjusted right. I got the low end set perfect, but my ski wont break about 55mph now. I have the "Junyard 1200" from YudLuz2, and it is a super strong motor, just wont go on top end like it should in my ski. Ive got it backed w/ a 13/19 Solas, but it ran 64 with a riva stage 1 w/ my old motor, it should be doing at least 66 or 67 now w/ teh head and reeds on it. Any ideas?

    BR9ES is a colder plug for higher compression.

    Do you mean the BR8ES I was told the only difference between that and the BR8ES-11 was that the 11 comes already gapped. Not sure about a BR9ES

    You need to get the right plug's.

    No 2 hulls are the same so one may be severall mph slower than another.
    Then theres intake ride plate bolt ons like carbs F/A pumps etc.

    You need to do one at a time it sounds like your going thru your carbs.

    Do you have the prop he was running and the same set up he was running.

    I dont think you understand what Im saying, im not going to get eth same numbers or even close that Ben was getting w/ teh motor because he has it triple piped. Im just saying that its not running top end like it should! IM thinking its my carbs are still not adjusted right. ive got the 110-120-95g-1.5N/S set up and Ive got teh lows set perfect, ski takes off like a bat out of hell, then hits 55 pretty damn quick, but wont go any faster?!?! What Gives? I cant figure it out, im about to take it to a shop and let them ream me a new a$$hole and set the carbs up and get it running right.

    55mph sounds like your running on 2 cylinders.

    I would get some new br8es-11s and see if that helps, I tried the 9s and it ran like crap until i put the -11s back in.
