Speed Question, Hoping there is not a problem?
I recently purchased an 05 Yamaha FX HO 160 HP (47 hours)
I thought that I had read that the speed at full throtle would be 62 mph.
I was only able to register a speed of 55 mph on the speedo in my first WOT day.
I did have a 3/4 full tank of gas and I weigh 245 lbs.
Trim was set at neutral.
Is there cause for concern?
RPMs were steady at 9500-10000
Any thoughts on this could help put me at ease.

Sounds about right. I had a 2004 HO which did 58 stock and 61 with complete Riva rpm kit on a low tank of gas on glass. This was on GPS by the way. The speedo is not very accurate.

Never trust the dream-o my GPS said 68.6 and my speedo constantly read between 82-83.
