Re: 95 opi max mercury 115 hp neutral problem

In the water you have back pressure/resistance.Out of water on muffs you have no pressure/resistance....so your idle runs at approx 200 RPM higher out of water.What is your idle reading in nuetral on the muffs.
Your problem may be as simple as adjusting the idle.I try and adjust to 950rpm on muffs,which gives me around 750rpm in the water.
