Best GPS/Fishfinder Combo For Jet Ski
These mounts are made for boats in general 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 Fishfinders being fitted to various jetskis, 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!Table could not be displayed.
Installing the Jet Ski fishfinder GPS
(From here on in I will refer to the Fishfinder/GPS combo as Fishfinder). There are two main 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.
Installing the transducer.
The transducer needs to be installed at the bottom of the jet ski. This can be either in the water or fixed inside the hull of the jet ski with epoxy resin, etc . It is safer inside the hull and has the following advantages
- Fewer holes to possibly make in the jet ski (There are usually openings you can use)
- Looks better, as it is hidden away from view
- Less likely to be damaged as it is safely out of the way
The disadvantages are
- Cannot take the water temperature
- Downward scanning sonars have to be fitted outside to work
- Slightly less efficient. The wave has to pass the fiberglass in both directions
- May only work on Single Layer hulls
- The transducer will have a bracket to hold it in place. This will require some drilling to attach with the screws to the hull. This will not be a problem if you seal these holes with silicone caulk, which will be solid when dry.
Some people do not want to drill holes into the hull to fit the transducers, for many reasons, including devaluing the Jetski. Some people have had success when just using epoxying the unit to the inside of single-layer fiberglass hulls
jet Ski fish finder mount – Installing the display unit
If you do not want to drill holes to mount the display unit, you can hold the display in place with a handlebar bracket. Something like
This is great as you do not have to drill holes. However, you may not always be able to put the fish finder in the exact viewing position you desire
Find a place that will be easy for you to see the display unit when sitting on the jetski. Attach the display to your chosen mount, and hold the screen in the position you want it to stay. Then mark with a pencil the location of your mount, and any holes that will need to be drilled.
When choosing the mount, you want something that gives you a lot of movement. This allows you to position the display as needed. It is also it is better if you get a mount that can be removed when not in useTable could not be displayed.
Connecting the Display to Transducer
Once you have decided where to put the transducer and display unit, these need to be connected together with the supplied cable. Drilling may be required if there is no way to fit this without it being intrusive when you are using the jet ski
Powering the fish finder for 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 Fishfinder 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 of some kind. 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 Fishfinder?
This will depend on the type of Fishfinder, but up to about 25mph seems to be the limit
