I've been having problems reaching the max rpm while in gear for 2 seasons now. I have a 1985 Universal M18, (14hp). It should reach 3200 rpm, but it only reaches 2200. In neutral it reaches the required wide open throttle rpm. The tach is good, I replaced the injectors last winter, the prop is stamped with its pitch and diameter, which are whats called for for this boat. I can only make 4 knots under power, and thats without wind or current. Any suggestions would be appreciated.
