Frequently Asked Questions
Q: Can this pump run dry?
No — running any raw water or engine cooling pump dry for more than a few seconds will damage the impeller and can lead to overheating; always confirm water flow before starting the engine.
Q: What size fuse or breaker should I use?
Engine-driven raw water pumps like this one are not electrically powered, so no fuse or breaker applies; they are driven directly off the engine.
Q: Will this replace my existing pump without changing the plumbing?
In most cases yes, provided the port size and mounting pattern match. Compare the dimensions in the specifications above against what you are removing before ordering.
Q: How often should the impeller be replaced?
A raw water pump impeller is a wear item; inspecting it at the start of each season and replacing it at the first sign of cracking or missing vanes is the standard practice.
