You can indeed install a GPS Fishfinder combo to a jet ski. There are a couple of things that you are going to need for this job. That is to pick out the GPS/Fishfinder unit that you want, and then get a compatible jet ski Fish-finder mount for the unit.

In A Hurry?

If you do not want to read the entire article - below are the choices made. Read on for the full story!

These mounts are made for boats but should work just fine on a Jet Ski as well. There will be some recommendations for these later, as well as links to 5 instructional videos of different Fish finders being fitted to various jet-skis, so you can see exactly what is involved.

There are two options:

  • No Drill. Use Handlebar Bracket to hold the display, Fit Transducer inside the hull.
  • Drill Holes. Monitor fitted in the exact best place, and Transducer mounted outside hull.

Obviously, there are reasons for wanting to do both. This article will hopefully help you decide precisely what you want to do!

Installing The Jet Ski Fish-finder GPS

(From here on in I will refer to the Fishfinder/GPS combo as Fishfinder). There are two major pieces to the Fishfinder. The display unit that needs to be fitted where you can read it as you are riding the jet ski. The transducer which needs to be installed to the bottom of the jet ski and is the part that actually detects the fish.

Powering The Fish Finder For A Jet Ski

The Fishfinder requires power, how you do this is up to you. You can either wire it to the battery that is already in the jet ski, or fit a separate battery for the Fishfinder.

Attaching to the existing battery will require more wiring, and may need some holes drilled, depending on the jet ski you have. The Fish finder does not use a tremendous amount of power, so this should not be a concern.

If you have a battery specifically to power the jet ski’s fish finder, then you can put it near to the power-in socket. This means you do not have to run a lot of wires. The battery will need to be held in place when the jet ski is moving, so will need a bracket. Get a removable one so that it can be taken out when not in use.

How Fast Can You Go On A Jet Ski With A Fish-finder?

This will depend on the type of Fish-finder, but up to about 25mph seems to be the limit
