Hello out thier I have a 1950 mercury KG7 10 hp it misses when u advance the throtle higher than half throttle. It seems more like a certian rpm tho because when you can advance the throttle up to full the engine runs fine untill the boat planes out and it hits that a certian speed then it misses. Any ideas? now ive replaced one coil and plug wire and both condensers and i reset the points i also cleaned and rebuilt the carb. Now the coil i replaced was cracked but so was the other coil just not as bad could that be a problem???

Yes both the coils had to be replaced
