I have a 80/24 it’s about a year old. When I turn it up to an 8 or over this thing starts to whine. Any help would be appreciated.

Try pulling off your prop and putting it back on turned 180 degrees

Mine has done this from day 1 as well. It seems to work just fine as far as speed/operation. Just a bit of an annoying sound. I I have tried all kinds of things but no solution.
Tried it but didn’t help. Thanks anywayOriginally Posted by catdude28
I have read that some of the motors do this. I have not run across this in my shop. I have no explanation as to why it happens. I could compare this to an airplane prop that whines when it spins up. Just my comparison. It would be a stab in the dark to fix and the only thing I would change would be the armature. It is the only moving part that would cause this. I would have tried the prop first then the armature. After thought I would say it is related to harmonics in the motor. Just a guess here.
Just my thoughts If you try anything post here and give results if you care to share.
Thanks
Had this problem with my Terrova. Long story. To the repair shop a few times with no fix. Repair tech suggested to rotate skeg a few degrees off center. I did and it helped some but didn’t completely eliminate it. I moved the skeg about 1/4 inch each way. Ended up leaving it there. I bought one of the fancy prop nuts like the TH marine one. Put it on and it’s been quiet ever
since. Eliminated the whine/squeal completely.
thanks
