    Stator shorted to GND '78 115

    Can a shorted stator be repaired. the wires entering the stator are OK. Does the flywheel come off easy enough to take a quick look at it? After inspecting and testing the charging system I found a defective rectifier. So like an idiot I installed the new one and fired up the motor. No...

    115 fuel hose leaking

    I have a leaking hose on the upper carb end. can I just replace all four pieces with regular 5/16" fuel hose? I see in the BRP diagrams that some have unique part number, probably due to the sharp bends. AND, looks like the plastic cable ties are the way to go over worm clamps. short of...

    78 115 thermostat housing removal

    :confused: I am trying to replace the thermostats on my 115 as preventative maintenance. The bolts are rusty and I managed to get the outer two loose, but the middle bolt head broke off.

    Shifting problems

    I have a 1978 Evinrude 115. The shifter will not come out of forward into neutral. I have popped the cable attachments from the motor and control box. The engine itself will shift into all gears fine, so my issue is with the shifter. I replaced the shift/throttle cables a few years back so...
