The BEST battery upgrade for your Fish Pro!

www.gcjetskifishing.com for all your Seadoo Fish Pro and Yamaha Waverunner jet ski fishing accessories!
In this tutorial video we show you just how quick and easy it is to install the GC Jetski Fishing 34 amp hour battery upgrade kit onto your Seadoo Fish Pro. The stock dual battery system is a poor design with each battery located in different parts of the ski requiring extra wiring and fuses which can also lead to failures. The upgraded single battery option from GC Jetski Fishing requires no extra wiring or modifications to your ski and will give you almost the same amount of battery capacity as a dual system, without any of the headaches!

Installed today. Thanks!!!!

[@robertquigley2431]

Thanks Glen. I'd been annoyed at my 2022 Seadoo FishPro fish-finder cutting out after 20 minutes of drift fishing, and this bigger battery has solved that. The install went well especially given I'm not the best at this type of stuff. Moving a tube to get the original battery strap off was necessary, and I had to cut a cable tie to get another larger tube out of the way for sliding in the battery. Finding the clip for unhooking the starter relay was a bit tricky. I used a sharpened iki spike to get the pilot holes for the screws and the screws went in no trouble at all. With a coffee break and fashioning a notch in an old screwdriver with an angle grinder, it was all done in under two hours. People who are good at this stuff would breeze through the install much faster. In a few years time when it comes time to replace the battery, I suspect getting the heavy battery out, past the cables might be tricky and I'll need a friend to help hold stuff out of the way. Thanks again Glen. Now back to the fishing...

Great upgrade Glen. I struggled with the new battery strap, but modified a pry bar like you did your screw driver and this made it a breeze. Waiting for your trolling rod holders to come back into stock

[@GCJetskiFishing]

Thanks Martin, yes the strap can seem impossible by hand but it's a breeze with the correct tools

Excellent vid have a few of your products now, always impressed with the quality

[@GCJetskiFishing]

Thanks Geoff, always appreciate the feedback. Thanks for watching!

[@richards6367]

Great vid, thanks

[@GCJetskiFishing]

Thanks for watching mate

[@princiotta0531]

Wondering if I could put this in a 21 seadoo rxpx300 so I can listen to my radio longer

[@GCJetskiFishing]

Hi there, yes it will fit that model ski

[@rayburkett4537]

Hey Glen im about to order you tray well 2 trays actually. The Mrs and I run a lot of electrical items, sound, garmin, marine radio and emergency lights. I decided on 2 30amp batteries. Do you see a problem with that? Thanks Ray

[@jasonboccella2242]

Can you run the bigger battery on front of the trophy and keep the original in the rear or do you have to have the same battery for both

[@allensaelee6707]

Have you made a battery bracket for the rear fishpro trophy battery bracket yet? We want to run 2 of those huge bad boys in our trophies.

[@GCJetskiFishing]

Not yet but it is something I am going to look into

[@allensaelee6707]

@@GCJetskiFishing 👍🏼 plenty of room back there just need a bracket to run the same parallel system of two same batteries & never get stranded! Lol

[@maximumeffort8829]

Hey how are you great video, i wanted to order for my 2022 RXPX that i run headlights on, do you think i can get this to fit on the smaller hull?

[@sea2sea2seevanlife92]

I'm interested... I've got a Sea Doo 2022 GTX 300 Ltd, this should work on this ski as well, yes? I always enjoy your videos, thanks!

[@GCJetskiFishing]

Yes it will work fine on the GTX platform. Thanks for watching!

[@maxhille8959]

Would it fit in my Seadoo Wake Pro 230 from 2020? I would also like to install a Lipo battery. Are there any problems or does it work without problems?

[@charliefourzero]

What is your bigger battery dimensions? So i could fi d a suitable battery for your tray in the UK

[@GCJetskiFishing]

It is a Motobatt Mbtx30u, you should be able to Google search for the dimensions

[@jetguyfly1]

Where can I find the 34ah version? When I Google mbtx30u I only find the 32ah

[@GCJetskiFishing]

They have just recently released an upgrade to the mbtx30u battery so as long as you are getting new stock it should be the upgraded version. Some places may still be selling old stock however

[@rayburkett4537]

Im just concerned they might not fit. I have two skis a 2021 230 GTR and 2020 130 GTI the batteries on both are placed differently

[@GCJetskiFishing]

I'm not 100% sure but I think the GTR and the GTR are both different to the fish pro & GTX so this kit will not work unfortunately

[@Killemgrillem00]

Hi Glen, do you sell the kit for the battery upgrade ? I have a 24 fish pro trophy and would like to upgrade the battery. I also had sea doo install a bilge pump; unbeknownst to me, the factory bilge runs when the battery is on all the time. I think it's going to draw too much electricity. Hopefully your 34 Amp battery will help..Thank you Dave.

[@GCJetskiFishing]

Hi Dave, yes I do sell it, you can find it on my site here www.gcjetskifishing.com/collections/sea-doo-fishing-accessories/products/seadoo-32-a-h-battery-upgrade

@@GCJetskiFishing My friend, i purchased the tray from you but the battery was not available. Any suggestions for a comparable battery here in the States that your holder would accommodate? Thank you Dave

[@GCJetskiFishing]

@@Killemgrillem00 Hi Dave, you will be able to purchase the battery out of Florida direct from Motobatt. The part number is MBTX30U

[@Killemgrillem00]

@@GCJetskiFishing Hey, Thank you much. I called Mottobatt, but I didn't get through. I went to Mottobatt and sight-saw the Batt. I ordered the Same through Amazon here at 32 AMPs. It's the same as on MotoBatt. Your tray is coming. Everything is good. Next is to hook up a tow valve. I will be offshore fishing here, though the ski is new, and I'll get a sea tow policy. There's no need to mess around offshore. What's important is the tow valve. Thanks again, Dave.

[@eliteAries]

Where can you get the battery in Australia since you cant shipped it?

[@GCJetskiFishing]

A quick Google search of the part number MBTX30U should give you some options in your country. They are commonly found in motobike stores

[@bayleybeatle]

Great upgrade How do I purchase? Regards Mick

[@GCJetskiFishing]

Hi Mick, you can find these on www.gcjetskifishing.com

Hey Glen will this work on my explorer pro 2023?

[@GCJetskiFishing]

Yes it definitely will!

[@johnwilson400]

I have the battery but didn't come with a tray, I can't find one online

[@GCJetskiFishing]

You can only get the tray from www.gcjetskifishing.com

Great mod. Have you installed a tow tap for a 22 fishpro sport?

[@ukspice69]

Any issues with heat on the bigger battery since it is close to the engine

[@GCJetskiFishing]

No problems with heat yet, it is close to the engine but as long as there is an air gap I think it will be absolutely fine

[@ukspice69]

@@GCJetskiFishing great because I already bought it

[@rickss69]

Would you recommend a larger capacity single battery in Lithium?

[@GCJetskiFishing]

Definitely not... Lithiums require a specific type of battery charger, the stator charging system on the ski engine is not suitable for lithium

[@rickss69]

@@GCJetskiFishing Asking because it seems most jet ski's charging systems barely take care of a single battery anyway. I would always charge between uses regardless of battery type with the appropriate charger. A ski's charging system evidently does not harm a lithium battery as they have been used for over a decade. Looking to bullet proof my offshore Yamaha with a single battery solution and I will be carrying a lithium boost jumper for emergencies.

[@GCJetskiFishing]

@@rickss69 A single large AGM for your ski battery and separate lithium jump starter would be my recommendation for reliability. The problem with lithium occurs when and if the battery ever drains significantly then it will try and demand a higher voltage from the ski's charging system to recharge the battery, but this higher voltage can very easily upset the lithium battery and cause a fire. As lithium technology progresses it will become less of an issue but it's personally just not a risk I would take on any watercraft when there is proven suitable alternatives already available. I used to work in motorsport and saw many lithium batteries puff up and sometimes catch fire due to not liking the charging voltage from the alternator. In a car it's a risk you can take, on a boat is a whole different story.

[@rickss69]

@@GCJetskiFishing I completely understand that fear and the reasoning from past experiences. Were these particular problems before the BMS technology used by top tier lithium batteries nowadays? Btw, my only constant draw will be from the installed 9" graph which would likely see a maximum time frame of 8 hours continuous use. Thanks again.

[@rayburkett4537]

I cant find this battery only the 32amp

[@GCJetskiFishing]

The 32 amp will work as it is the same dimensions and same part number but you must be finding old stock, as any new stock should be the newer version 34a/h

[@MrRefa3ee]

Does it fit in the seadoo gti 2021?

[@GCJetskiFishing]

No sorry I think the GTI has a slightly different battery setup

[@ShawnFromFL]

Are these available for the US?

[@GCJetskiFishing]

Yes we ship worldwide

[@ShawnFromFL]

​@@GCJetskiFishingWow, thanks for the fast response! This will be for a 24 RXT-X 325. It has the OEM Haijiu HTX20L-FA 18Ah with 1-3/8" (roughly 35 mm) between the battery wall and the motor. Guessing it's same as the 300 setup from 23 but wanted to run by you first. Do you think it would work for my needs?

[@GCJetskiFishing]

@@ShawnFromFL yes I'm pretty sure it's the same. If you want send some pictures through to [e-mail] if you want to check

@@GCJetskiFishing Order placed. I'll let ya know how it goes on my 325 RXT upon installation. Thanks!

Would it fit in my Seadoo Wake Pro 230 from 2020? I would also like to install a Lipo battery. Are there any problems or does it work without problems?

[@GCJetskiFishing]

Yes it will work on the wake pro. I prefer AGM batteries as lithiums are not suited to the charging system on a ski
