Manual Conversion Boat Steering Kit 99 | 4Boats

Manual Conversion Kit 99 is a compact retrofit kit designed for straightforward conversion of mechanical marine steering systems. Ideal for replacing worn linkages or adapting wheel-to-tiller setups on small to medium boats (fits steering shafts Ø8–20 mm), it provides a reliable, low-profile solution with easy installation.

• Compatible with many mechanical wheel and tiller steering setups — fits steering shafts approximately Ø8–20 mm and common wheel/tiller link geometries; verify shaft diameter and mounting space before ordering.
• Kit contents: conversion plate (approx. 120 × 80 mm footprint with multiple mounting holes), adjustable linkage rod (adjustable length range ~150–300 mm), 316 stainless fasteners (M6 and M8 bolts, washers, nylock nuts), and fitting instructions.
• Materials: marine‑grade aluminium plate with corrosion‑resistant finish, 316 stainless linkage and fixings, and low‑friction nylon/PTFE bushings for smooth operation.
• Corrosion resistance: hardware is 316 stainless; plated/aluminium components treated for marine environments to resist salt‑water corrosion.
• Typical installation time under 2 hours using common hand tools; basic drilling or hole alignment may be required depending on helm. Simple fitment guide included with mounting diagrams and torque notes.
• Fitment notes: suitable for mechanical (cable or rod) steering only — not for hydraulic or electronic power steering systems. Check clearances and shaft interfaces prior to installation.
• Warranty and support: two‑year limited warranty (terms apply); spare parts and technical support available through 4Boats.
• Part reference: Kit 99.

Often compatible with many small-to-medium helms; verify mounting patterns, shaft diameter and clearance before ordering.

Verify helm load and throw limits, shaft diameter and clearances before installation to ensure safe operation and reduce returns.
