Common Concerns Answered
Is the Johnson Pump CM90 expensive?
While the initial investment for the Johnson Pump CM90 may be higher compared to basic bilge pumps, its robust construction, extended motor life exceeding 5,000 hours, and superior flow rate (23.7 GPM) offer significant long-term value and reliability for critical marine applications.
Will I need special adapters for installation?
The Johnson Pump CM90 features a 1-1/2" outlet. Depending on your existing plumbing configuration, you may require appropriate adapters to seamlessly integrate this pump into your marine system.
Is this pump overkill for my needs?
The CM90 is designed for users requiring high-volume circulation, such as for robust livewell systems or demanding water transfer. If your application does not necessitate a 23.7 GPM flow rate or the specific liquid handling capabilities, simpler pumps might suffice. However, for applications demanding efficient and consistent high flow, its specialized features are precisely what's needed.
