    Default Please help Im going crazy.

    I have a 2010 mecurey 60 hp 4 stroke on a 198DLX carolina skiff
    Old prop Apollo xhs 10.5 x 13
    New prop spifire 4 blade 10.6 x 12.

    My problem was with 4 people and gear it was not planning off. I bought the spitfire and it planes off great and fast now...... But at 1/2 throttle the controles beep/alarm 6 times and motor starts shakeing like its going in to safe mode.

    I put old prop back on and runs good no alarm.

    The boat will plane off with only two people in it with old prop. But with heavy load it just will not plane. I have no gauge in boat to Reed RPM. Please someone help me solve this problem.

    If you are switching from a three blade to a 4 blade it takes more torque to turn the 4 blade, You need to get a tachometer to prop the engine properly. you need engine to reach wide open throttle in order to do this
