I just bought an Angler 180f (center console) w/ Yamaha 100 4 stroke
2002. At 1500-1900 rpms I have a whining noise coming from the engine.
When in full turn to either side the sound is not there and will not
occur at any rpm. We just had a new prop Michigan Wheel 13 1/4 x 17"
aluminum put on. Could it be the prop?
Any ideas on this? The former owner says he had no sound other than
the rumble of the 4 stroke. I am stumped. I might try putting the old
prop back on. Any thoughts?
Thanks
