12x18p

Testing a mates mercury 12x18p cleaver he has modified.
It definitely works

What rpm was the run?

[@merc625]

5800

[@RoggerLemes]

Why did this 12x18p cleaver only reach 5,800 and not reach 5,900 rpm. Lost water pressure? Could you increase the engine height even further with this cleaver?

[@merc625]

The motor was raised as high as I could safely go. 5800 is pretty spot on for rpm The prop has a lot of blade area the slip is only around 3.5%

@@merc625 Do you believe that to get more rpm with this propeller you would have to increase the height more, also add a lwp or would it be better to reduce the diameter, maybe 11.5??

[@merc625]

@@RoggerLemes a transom mount water pickup and raising the motor would be the way to go
