It fits great

I needed to power a high volume water pump, diver air compressor and hot water exchanger for my gold dredge, the stock engines available in the weight range I could float on the dredge (80-90 lbs) just didn't have the torque/HP I needed so the solution was to use a modified GX390 to get the power I needed for the job. Not only did I get the power but I also got a lot more reliability that I've gotten in the past from a stock GX390 pulling a large load for hours of time - Rods just didn't hold up on the stockers. This solution gave me power to spare and reliability for seasons for trouble free operation.

Worked as needed
