I was wondering if your guy's plugs are always wet with fuel when you do a read. My 787 gtx is just saturated with fuel, although the color looks good. I am used to my snowmobile and dirt bike which always are dry whenver I check. The maunal says to adjust the low speed screws the same tuens out, but I hear alot of guys say run the mag side on an extra 1/2 turn out.
I think boat might be getting too much fuel as slugging throttle response when in water, great out of water.
