Help! I have a Merc four stroke 115EFI that was running great with WOP at about 5000 rpm. We had a battery post issue that was fixed - but now the engine vibrates like it and will only go to around 3500 rpm. Almost like it lost a cylinder or something. It's in the water and a pain to take...
Just bought a pontoon boat with a 115hp Mercury 4 stroke. I cannot engage the engine tilt lock. Is it possible that on this particular pontoon it won't allow the engine to go all the way up to engage it?
