Questions & Answers
Is this a genuine original part?
This is a quality aftermarket launching wheel set, not a branded original-equipment part.
How do I know if it is compatible?
Check your transom can take the 14 x 20cm bracket, with 6.5mm holes on 10 x 13cm centres, and that your loaded boat stays within the 120kg working load.
How should I maintain them?
Apply marine grease to the wheel axle regularly for smooth operation and longer service life, and keep tyre pressure at no more than 25 psi.
Note: Not for highway towing. Please verify your transom dimensions against the specifications above before purchasing. Domain: 4boats.co.uk
