unless its a new L2 lower unit its 1:86 gears as thats all they make. except for some of the v4 lowers and I think they are 2:00 or so and you would over tach

How are you calculating your speed? I would say your gear ratio is the same, however it is possible that you got a commercial V-4 case as a replacement. If that happened, you would have noticed a big difference in the holeshot. Another possibility is what type of oil was installed in the new case. This can make a difference, especially in the top end. Otherwise, I would check the prop very carefully for pitch accuracy, it's possible that one of the blades got distorted without evidence.

this is with gps and all oil is same as always ran, would the prop lose 10 mph and the holeshot is still goood

[gearcaseman]

Yes, this is a possibility. Also, you may have disturbed the hub fit in the prop and it could be slipping at high R.P.M.
