Mariner Trouble

Hi I hope you will be able to help me! I have a 1979 Monark with a 115 horsepower Mariner motor with a 24 pitch prop. Recently I have had trouble getting it to plane out. Then while running down the lake it lost all power and would not plane back out. It would go in reverse fine and only at idle speed in forward. Any ideas on what might be my problem? Thank you so much for any input you may have.

Traci, 

First place I'd look is in the shift throttle linkage area. Sounds like something broke. Try some vent holes if the prop is a thru hub - add some blade roll if it is a chopper.
