The 5 HP rating refers to 5 HP @ 2000 psi but the maximum psi is 3000 psi which would require the 6 HP rating. So to be able to utilize the full capability of the pump, the correct rating is 6 HP.

I installed this pump on a 5 hp engine and it works OK, but I can stall the engine before it builds full pressure. I get around that problem by bumping the lever a few times so the engine can recover between bumps. This is only required when it first bites into a big log. The rest of the time it operates quickly without bogging the engine. If I were doing it over, I would choose the 11 GPM pump for a 5 HP engine.
