.I have excellent experience when changed to normal spark And go to iridium NGK , I did in my waverunner Yamaha 4-stroke 160 hp in my Mercuiser 7.4, giving better start and better acceleration, I plan to do the same with my Robalo 25" Dual engine '96 Ocean Pro 225 each,. Now using spark plugs champion QL78YC. I would like to know the part number and brand for IRIDIUM and hear comments on this idea.
Thanks in advance
