If you are referring to me, all my testing is done 2-1/2" below pad

Tried a different prop, and she's beat up a bit.

99 TR-19 PD DC
99 Merc 175EFI
8" JP 2.5 below pad
25P Tempest
1/8 Gas
Driver, Full load for two, Empty wells
67.9 GPS @ 5900rpms

Added 8" jackplate.
69.1mph
Full load for two
Half tank of gas
Just driver
Ran out of room

1/4 tank 69.6mph @ 5700rpms

Can't see 76.2 on 175 tr-19.. perhaps you meant 67.2.

Reran with a full tank, hit 64.2mph. Think I need to trim more but I run out of room where I'm at.



Also edited my other post.
