Questions & Answers
Is this a genuine original part?
This is a premium quality aftermarket replacement part, manufactured to meet or exceed original equipment (OE) standards for fitment and performance on MerCruiser engines.
How do I know if it is compatible?
We recommend checking your current belt for the number 57-65607Q or measuring the length. This belt is exactly 37 inches long and fits the 120, 140, 2.5L, and 3.0L GM-based MerCruiser engines.
Why is my power steering belt squealing?
Squealing usually indicates the belt has become glazed, stretched, or is under-tensioned. If tensioning the belt does not stop the noise, it is likely time for a replacement to prevent sudden failure.
Note: Please verify your original part number or measure your existing belt (37" / 940mm) before purchasing. For more high-quality marine parts, visit 4boats.co.uk.
