I Made Telling You About This Lower Unit
To Give You All Some Understanding Look At The Calculations Below
As One Goes Up In Pitch,One Must Reduce Diameter To Maintain RPM In Most Cases. Prop Science Is A Black Art ...A Pure Guessing Game At Best
Most Lighter High Performing Hulls Will Have A Slip Of 8-12% When A Driver That Knows How To Trim And Setup "X Height" Is At The Wheel
This Lower Should Only Be Used On Light And Inherently Fast Hulls
Assuming Your Engine Reaches 5800 Full Throttle RPM The Following Math Applies.

Keep in mind, this lower has aftermarket non standard gears
There are no returns on this for any reason.
There are no warranties expressed or implied.
Since I am not there doing the actual installation on your motor, since I am not there to inspect your control system, since I am not there filling it with lube to the proper level allowing air to evacuate the hollows of the propshaft carrier, or doing the actual shift shaft adjustments, since I have no idea if your shift linkage is binding or if salt water has caused the cables to bind internally, Since I have no idea the condition of your control box , since I have no idea if the weld on that stainless linkage bell crank is fractured (common problem known to 60 deg motors)...there IS NO WARRANTY ON ANY OF MY LOWER UNITS. NONE. ZERO.

This Is Just One More Reason I Do Not Place Warranty On A Lower Unit That I Personally Am Not Installing
Linkage and proper adjustment is super critical on any lower unit that uses the push pull shaft bell crank system as EVINRUDE uses
You agree that you are purchasing this lower unit with non standard ratio gears and assume all risk as to how it performs on your own boat.
All Bearings Have Been Changed Out For Brand New Koyo USA Bearings,
Resealed Using OEM Seals etc.
