Ultraflex P1218 Trim Tabs 12"x18" | Ultraflex 41847V

Ultraflex P1218 is a pair of steel trim tabs measuring 12"x18", designed to stabilize and optimize the trim of motorboats by actively correcting its heel and angle of attack on waves. The set is a component of Ultraflex mechanical/hydraulic trim systems and is compatible with the manufacturer's corresponding actuators and control panels, allowing for quick flattening of the boat during acceleration, shortening the time to plane, and reducing so-called porpoising (bow rise). The 12"x18" plates offer a large lifting surface, which is effective on heavier vessels or those requiring additional lift force at the stern; stainless steel ensures rigidity, corrosion resistance, and long service life in marine environments. Installation is on the transom – each plate is flat-mounted to the stern, with the lower edge close to the waterline, maintaining axial alignment relative to the keel and symmetry between the right and left sides; actuators (depending on the Ultraflex system) are attached to the plates and transom according to the manufacturer's template, routing cables to avoid bends or abrasion. The set is supplied as a pair (port/starboard), enabling independent correction of lateral heel and simultaneous lowering of both plates for longitudinal trim adjustment. The plates are intended for use in both fresh and saltwater; after installation, it is recommended to use marine-grade sealant and periodically check fastenings and hinges.

Technical specifications:

Product type: Pair of trim tabs (left + right)

Plate material: Stainless steel

Single plate dimensions: 12"x18" (approx. 305x457 mm)

Mounting configuration: On transom (stern), hinge at the top of the plate

Application: Motorboats – trim and heel correction

System compatibility: Ultraflex trim systems (plates compatible with dedicated Ultraflex actuators/controllers)

Number of pieces in set: 2 (pair)

Operating position: Independent control of left/right plate (depending on used control)

Operating environment: Fresh and saltwater

Product advantages:

- Large 12"x18" surface provides a noticeable stern lift effect and quick planing. - Stainless steel increases durability and corrosion resistance in marine conditions. - Pair (L/R) allows precise correction of lateral heel and longitudinal trim. - Transom mounting does not interfere with hull geometry beyond the stern area, limiting drag outside active operation. - Compatibility with Ultraflex systems allows coherent selection of actuators and control panels. - Improved cockpit visibility by lowering the bow during acceleration. - Reduction of porpoising phenomenon and more stable boat behavior on waves. - Ability to adjust effect according to load and weight distribution through independent side control. - High plate stiffness reduces deflection and increases effectiveness at higher speeds. - Simple cockpit operation after integration with Ultraflex controller.
