2001 Tuffy Osprey W/ 60hp Evinrude E-Tec Tiller Question
There is a guy named Charlie in New London that is an Evinrude only repair center,,,he know's his stuff,,,look up his number and give him a call
I HAD SAME PROBLEM..switched out the tach,,,fixed my concern about LOW RPMS,,you have to make sure you connect to the correct pole
You also may want to consider getting your prop cupped and ventilated,,,John Janake in Burlington is the man for that,,PRO_PELLERS is the company name
24mph for 60hp tiller @ 3500rpm with 13 pitch prop (assuming 2.67 gear ratio) would be INCREDIBLE by my calculations. More like impossible.
Even if it was an 18 pitch prop that still wouldn't account for that.
I think either your tachometer is off or your speed is off. How are you measuring both of those variables?
