Our customershave some nice things to say about the Evolution Marine Shaft System (EMSS)."It runs ultra smooth. There's no question it eliminates vibration." --Glenn Holland,Holland's Boat Shop, Mill Lane, Belfast, Maine"For the first time in my sailing experiences, it is a pleasure to run the engine. Nothing vibrates, not even the coffee pot." --Gordon Bok,Folk Singer, Rockport, MaineOwner of a 32'Triangle S/Y"I must have done a good job aligning the shaft. We can serve tea on this aft deck." --Don,Yard Foreman, Yankee Marine, Yarmouth, Maine"The Boat is extremely quiet. While cruising, my wife can now use her cellular phone in the aft cabin." --Dr. Robert Knowles,Cumberland, Maine"We are impressed. After measuring the decibels a second time, there are no changes. The readings stand. The decibel differences are outstanding." --Bill Hudson,President, Ultra-Sonics Acoustics, Winthrop, Maine"On Parisen's boat (38'Duffy with a 420-h.p. Lugger diesel), the individual who was going to 'swing'the compass stated he was ready and to start the engine. The engine had been running since he boarded. Need I say more?" --Roy Lupien, Thomaston, Maine"If you stand at the mast with engine turning 1,700 to 2,000 r.p.m., you don't know the engine is running" --Jack Sanford,Attorney, Camden, Maine"I agree with my friend, Guy Fisher, who stated, 'I have never been in anything, whether a truck, boat, or construction equipment powered by a diesel engine that was smoother than this boat." --George Oliver,Rockaway Point, Long Island, New York"The boat is running superbly. I never thought she'd be this fast." --Craig Stephens,Harpswell, Maine
