I have a bmax with a 2 in shortie bravo shop late style lower gearcase and i need to know if it will fit on a standard bravo one lower unit if u change the upper drive shaft to bravo one shaft?

Also will a new imco 2 inch lower bravo one style gear case work on a late style bmax if you put the bmax upper driveshaft in it. Im thinking no reason they wouldnt but would the water passages match be the same through the lower unit?

I understand the imco lower gear case has the low water pickup being force fed all the way to the sea pump.
The water pickup on an imco just needs to circulate water to the top of the b max to cool the whole drive but do the water pasages match is what i need to know.
