I've got a friend ....
Lets say he's got a heavy 21 foot v-hull jet. Damn near 4,500 pounds worth of boat and "stuff"
Pump is a Berk 12jg with a Mag Bronze Legend a/b ( I believe this is equal to a Berk A)
Set-back, inducer, droop, yada yada yada
The old motor dyno'd 613hp on a Super Flow and spun the pump at 6400 rpm
The new motor makes 700 hp at 7000 rpm
670 ft lbs at 5200
These numbers came off of a DTS dyno at 98 degrees room temp and shitty barometrics.
Any pump gurus wanna give an opinion on what impeller would best suit a boat like this? For my friend
Intersted in hearing all aspects.
Thanks in advance
