Hello, this is my first post having just joined the forum. We recently purchased a 2010 Fasdeck 2220, VP 5.0 engine (270HP), SS DPs. During the test run I noticed vibration in the steering wheel at about 2900rpm...the boat needed about 3000 to get up on plane. The vibration was visible and reminded me of needing front tires balanced on a car...it disappeared above and below 2900.
The head mechanic at the dealer checked for obvious issues such as bent prop, shaft alignment, etc and then took it for test run in the water (I was not able to attend) and reported back that everything is fine - the boat has a natural harmonic at that point “as most boats do in this size and with dual props”.
I trust I am getting the correct answer...but curious if others have experienced this on similar boat setups. Is there anything that can be done to mitigate/change the harmonic...and presume I need to avoid running for extended period in the rpm band of vibration.
Boat located Lake Wylie, SC....this is our second boat...first was a 1984 Regal bow rider, bought new...just now getting back into boating(!)
Thanks for your inputs!
