I have a 2002 Merc EFI 225hp motor which I recently purchased. I have been trying to get this set up with jack plate adjustments and took it ouy for a run today. It worked Ok at first then it sputtered getting out of the hole a couple times. I let it sit a little, while I fished a favorite spot but when I tried to go it bogged down and could not get the boat on plane. I had to limp back to the dock, 2hrs. Now I am running the champion plugs it calls for but a couple outings I ran the equivalent ngk plugs. Could I of done damage. I ran the champs last weekend and they worked fine then. I am taking it to my mechanic tommorrow but I am just wondering if anyone had any ideas as to what it could be. It felt like I was trying to pull up a 500lb water skier and not getting on plane.
