115 Mercury 4-Stroke - no RPMs

[motorman]

My new 115 Mercury FEI outboard has the slows. The max RPMs I get at full throttle is between 3800 and 4000. I have had the motor to the Merc dealer twice to correct the problem but still no R's. It should rev to 5000 RPM minimum with no problem. The dealer seems to be loosing intrest in fixing the problem. Is there a problem with the 115 HP 4-stroke?

Howdy Motorman.<br />What boat do you have the Merc on? What prop are you running? Did the engine ever run properly?<br /><br />Let us know.

I agree with JB, I'd make sure I had the correct pitch prop for your boat weight etc.. I have an '02 90 hp Merc. 4-stroke on my 20' Bennington pontoon. Engine turns 5300 rpm with 13" pitch prop.. Three people and full tank of fuel. Dealer advised using 11" pitch for max rpm which is 6000. I think max of 6000 rpm is same on your engine.

JB had the right question. Did it ever turn faster???

Did you ever get this fixed?????? Just bought a 115 hp Merc 4 stroke EFI and will probably being playing with the props soon to get the proper RPM's. If you did get it fixed, what worked?
