    The engine fires very well with the new spark plug and the new ignition system components. I also set the correct timing. But boat still run only with the maximum speed of less than 10mph. and the third cylinder pressure is 110(cylinder is warm) and 100(cold). How can I fix the issue of slow?

    I did another timing setting by multi-meters with beep function. It continued to beep even there is a obvious gap. So I stopped when it changed from 0.3 to 6.9 and mounted the cap and connected the line to spark plug. also I started the motor. it worked. I will do a water testing and check it...
