Designed, not adapted

Built Around the Collars

The idea was simple: stop treating a jet ski like a small boat. We wanted a Spot Lock setup that felt like it belonged on the ski from the start.

JFM Spot Lock was developed around our Version 4 collar platform, using purpose-designed front and rear mounting systems and added collar reinforcement. We show customers what the system does and why it works — while keeping the fabrication details that make it unique within JFM.

After multiple design revisions and extensive on-water use, the Sea-Doo and Yamaha systems are ready to be matched to compatible customer setups.

System Up Close

This short walkthrough explains the JFM Spot Lock trolling motor setup, its collar-mounted design and the main components included in the system.

The battery box and power-system setup will be covered separately in a dedicated video.

Why it is different

The Motor Mounts to the Collars

The JFM collar platform carries the mounting system and adds stability around the complete fishing setup. The result is a purpose-built system rather than a generic motor attached directly to the ski.

Front or Rear Mounting

Two purpose-designed mounting options allow the system to be configured around the ski and the owner's preferred fishing layout.

Reinforced Collar Platform

Extra support and strengthening are added to the collar assembly to handle the motor's weight and operating loads.

Sea-Doo: No Hull Drilling

Current Sea-Doo Fish Pro installations do not require holes to be drilled into the ski.

Yamaha: One Hole

The current Yamaha installation requires one single hole, while the main system remains mounted through the collar platform.

Quick Release

The motor and power components retain quick-release connections for practical removal, storage and servicing.

Existing V4 Owners

Existing Version 4 collars can be upgraded with the required JFM reinforcement and support components.

Support Where It Matters

The motor creates different loads from ordinary collar accessories. The Spot Lock setup therefore uses additional support beneath the collar platform, designed specifically for this application.

We deliberately do not publish bracket measurements, material specifications or fabrication details. Customers get the benefit of a tested JFM system without us giving away the work behind it.

JFM power system

Battery Box,
Battery & Charging

The battery system will be sold separately from the JFM Spot Lock motor package. This gives customers the flexibility to choose the complete local package or source the approved battery through a partner closer to home.

The JFM weather-protected battery box is being designed specifically for Sea-Doo, with a revised mounting arrangement planned for Yamaha. Quick-release power components are retained so the battery system remains practical to disconnect and remove.

Lithium batteries will not normally be shipped internationally by air because of the high freight cost and dangerous-goods requirements. JFM intends to support international customers through approved local battery suppliers and partners.

JFM Battery Box
