Pros
- Passes 13/16 in solids, so muddy water with stones and leaves goes straight through
- Clean-out port and included tool let you clear a clog without taking the pump apart
- Heavy frame and isolated engine mounts take job site abuse
Cons
- Costs more than twice as much as a 2 in semi-trash pump
- Honda does not publish head or weight for this version in a reachable source
