SOMETIMES THE GEAR THAT POPS UP TO ENGAUGE THE FLYWHEEL STICKS. WHEN THAT HAPPENS, THE STARTER WILL HUM BUT THE POP UP GEAR WONT POP UP. IF I TAP ON IT, IT WILL POP UP, ENGAUGE THE FLYWHEEL AND THE MOTOR STARTS. DO I NEED A NEW STARTER?
Had the same problem with a starter on a Merc 150. Took starter apart. The end plate (opposite end of gear) socket that accepted the shaft was tore up. Went ot Budget Boats and got a replacement for $85.OO.
KJ, HOW OLD WAS YOUR MOTOR? MINE WAS RUN A LITTLE IN 2004, (PREVIOUS OWNER), BUT I HAVE BEEN OUT ALMOST EVERY WEEKEND SINCE APRIL. I'LL HAVE TO GET INTO IT TODAY. WORK HAS BEEN KILLING ME LATELY AND HAVENT HAD THE TIME. THANKS FOR THE REPLY.
I have a 94 200 merc, and if it sits awhile , it does the same thing, I was putting a shot of wd40 every once in awhile on the shaft , it worked fine, then I discovered if I put a little hot sauce reel oil on it, it goes all season long with no problems. [smile]
RYASON, Mine are 1993 Blackmax's. I tried oiling the gear shaft a few times before I took the starter apart, but it still would do it. Started off as an intermittent problem, but become too frequent, had to use the starter rope a couple of times. If you take your starter apart, just make sure you make it up pretty good so you can put it back to together properly. When you get it apart the brushes in the end plate will spring up out of position. To put it back together the brushes have to held down in position while you slide it together. I used a pair of large scissors opened up to hold the brushes in their proper position, slide it together and then pull the scissors out and slide it altogether. Karl
