Boat Hut Insight
When considering a jackplate, remember that while the quick hydraulic lift is a great feature, the real game-changer is how it affects your boat’s handling in shallow waters. If you’re fishing or cruising in areas with fluctuating depths, the ability to instantly adjust your engine height can save you from costly prop damage. Also, pairing this jackplate with SeaStar™ steering cylinders not only maximises engine tilt but provides smoother, more responsive steering—something every boatie appreciates when navigating tight spots. A tip: double-check your transom bolt pattern before purchase to ensure a perfect fit, saving you time and frustration during installation.
