Mike I have a Troy Built 6.75 HP (model 01904). Would this pump be a good replacement for it? Do you have any other recommendations? We use it just around the house and barn so it's not used a lot but at times can run for several hours on a job. Thanks

Answer
Please confirm you have a 3/4" hollow engine shaft. This would be a great pump, however I do recommend the fully plumbed version so it comes with the inlet and outlet fittings, unloader, thermal relief valve, and siphon hose. This way you just need to take off the old pump, slap this one on and you are ready to go!

Fully Plumbed Pump

3/4 in shaft by what length?.Is the mounting bolt pattern regular 2.5 in square,these are the mosssst important things you should advertise!!!,NOT the rest of the garbage

Answer
There are multiple locations this pump can bolt on. What brand engine do you have? This will bolt up to any 3/4" horizontal engine shaft, that was produced in the last 10 years.

can I put a 3000 psi pump on 4hp motor

Answer
No, you will need to attach this to a 6.5 HP engine or larger. We do not have a triplex plunger pump compatible with a 4 HP engine.
