Frequently Asked Questions – ImpelPro Impeller Pullers
Welcome to the ImpelPro® FAQ page. Whether you’re a DIY boater, a marine mechanic, or just curious about impeller maintenance, you’re in the right place. Below you’ll find quick answers to common questions categorized for easier browsing.
Product & Fit
Which size ImpelPro should I choose?
- Standard fits impellers 1‑9/16″ to 2‑9/16″.
- Large fits 2‑9/16″ to 4‑5/8″.
Measure vane tip‑to‑tip across the center of the impeller, not the hub. If you’re impeller is 2 9/16”, we recommend using the Standard. How to Measure
Can one puller remove all impeller sizes?
No. We offer two sizes to ensure a secure, non‑slip grip and safe removal. Using the correct size prevents slippage and damage.
Does ImpelPro work on outboard engines?
No. ImpelPro is designed for inboard engines (including marine generators.)
Do I need to remove the pump from the engine first?
Usually no. The compact design fits tight spaces, but access varies by engine layout. If access is limited, removing the pump may help.
Any safety steps before removal?
Shut off the engine and shut off the water to the cooling system by closing the seacock (ball-valve).
What materials are the tools made from?
Marine‑grade 316L stainless steel and 356‑T6 aluminum alloy (Brinell Hardness 90) for corrosion resistance and strength.
What comes in the box?
Puller body with thumbscrew, two different sized rods and card with QR code for instructions.
Can ImpelPro remove a stuck or partly melted impeller?
Yes. The design is intended to remove stuck or partially melted impellers without damaging the pump when used as directed.
Using ImpelPro
How do I use the tool?
ImpelPro pullers may look similar to tools on the market, but they do not work the same. ImpelPro has a bearing for leverage. It does the heavy lifting.
Lube the threads. Insert the puller arms into the water pump housing avoiding the cam and centered across the diameter. Engage the teeth with the impeller by hand tightening the thumbscrew, and use a 9/16” wrench on the nut to wind the impeller out smoothly. For instructional videos and step-by-step instructions, please visit How To Use ImpelPro Impeller Puller.
What wrench size do I need?
Use a 9/16″ wrench or socket on the top nut—don’t use tools on the thumbscrew or arms.
Do you provide tutorials?
Yes—step‑by‑step video and printable PDF instructions are available on our “How to Use” page and via the QR code in your package. How To Use ImpelPro Impeller Puller.
How often should I replace my impeller?
We recommend every 100 hours or once per year—whichever comes first. Always check your engine manual.
What are common signs of a failing impeller?
Cracked or missing vanes, reduced water flow, or unusual whirring/squealing noises. Your engine may start to overheat. If you put your hand on the face plate to the pump, and it is warm, it is likely your impeller has failed.
