I switched this motor from one boat to the other. It worked perfectly on the older boat now it surges at 2400rpm like it wants to rev higher but keeps running up to 2600rpm and back to 2400rpm and won't rev any further. It idles smooth and quiet and runs past 2000rpm smooth. I am using the same fuel tank, fuel fittings, battery-everything is the same but the boat. On the advice of another boater, I changed the plugs to new ones with no luck. Plug #4 had a black wet insulator where the other 3 had white insulators. I have disconnected the linkage and moved it by hand to rule out that. From what I read these motors are bulletproof but this has me stumped. I don't have a dealer close by that I would trust so has anyone here had this issue that could point me in the right direction.
