Cordless Makita Grinder rusted solid after being salvaged from a sunken boat.

- Amazingly, this makita grinder was on board a local fishing boat that sadly capsized.
Luckily amd thankfully, all the crew were rescued, and no one was injured.
The boat was eventually recovered, and this grinder salvaged from inside after laying submerged in sea water.
The grinder was only a few weeks old, so it was dropped in to see if it could be repaired.
The batteries were obviously completely destroyed, and it looked like this grinder was too.
But in a true testimony to makita quality and repairability, all it needed was a switch, battery receiver, and a few spade connectors.
It was unbelievable after seeing the amount of corrosion that was on it.

I guess most technician would just reject working on this, even waiting for it to dry. But it makes good content for a UA-cam channel 👍And indeed, best advertisement ever!
i would at least try to rinse the salt before letting it dry.
Yes it's just fun video content. I hate throwing things away but if I had Deans workload I would just bin this grinder.
It's a makita I would have took it and as soon as I heard it run I would have gave it some new nsk bearings cause it's just gonna cook itself with those rusted bearings
I have a small amount of Makita 18 v power tools, was thinking of selling them and putting the money towards Milwaukee 18v tools but after seeing this think I'll just keep adding to my Makita range. Top work 👍
Lol Milwaukee is crap, its all marketing. See others of Dean's videos, they are not meant to be repaired, have the tiniest chinesium bearings inside and the circuit boards are not potted which means if used outdoors they will burn out. No spare parts either, all the insides is a complete unit, including trigger and battery contacts.
This is the exact reason why I've been a Makita customer for decades. Solid machines, a pleasure to use, fair price, and spares are easily available. I've hardly had any issues with them, and the ones I had were easily fixable or were being taken care of by customer service.
Yes..I like that have isolated diver chips motor
Unbelievable!! It just goes to show that a quality item in the hands of a first class engineer can be salvaged.
Not just a brilliant ad for Makita, but also an example of your skill at repairing ANYTHING, regardless of the state it's in when it walks through your door!!
There is no substitute for quality. Plus parts availability is a large factor. Plus having a man who knows what he is doing. Fantastic video Dean.
Step #1 after salt water immersion is to rinse the hell out of it with warm fresh water, then finish off with deionized water in an ultrasonic cleaner if you got one. As soon as it came in the shop it would have been best to drop it into a bucket of tap water with dish soap to start sucking the salt out of it.
I’m not sure how good the contact cleaner does with such high concentration of salt. It can deal with some ionic contamination but saltwater is best treated with fresh water first.
Drying it out first is not the best with salt on it. Sure it has to be dried after the rinse of course.
A big problem with salt and stranded wires is that they wick the saltwater into the wire. So that controller may well have been exposed to some salt wicked through the wires. But they could have been lucky. Sad for such a new machine.
I’m mighty impressed that it still works, though. Even if it won’t last as long as a new machine, it’s still better than going direct to the dump.
Makes me glad I buy Makita tools.
Not only advertises the Makita build quality, but also your skills and knowledge, hat's off you 😎Dean
I'm just an experienced DIYer and have a few inexpensive tools that come in handy.
On the other hand, when I need tools I can rely on, I choose Makita tools, most of the time Brushless, and every time I watch your videos, it reinforces my ideas. Indeed, I think that when you buy this kind of tool, repairability is more important than pure performance.
Keep up the good work, friendship from the south of France.
(and sorry for the probably approximate translation from the French language!)
I've only used Makita for 40yrs
💪
Fantastic.Kudos to Makita quality.
Lovely..... but you sounded excited !! Great repair and indeed what a statement for Makita quality !!
Let’s hope marketing will never take over at Makita company like at Milwaukee. Repairability is the most important feature of any good tool. Not power and fancy advertising.
Special mentioning of Dyson household equipment here…
They even did power with xgt stuff ;)
Couldnt be happier
What a fantastic result
I have bought makita for years and the service is great
One time the terminals broke on one side of my double lxt charger they replaced it just like that
The worst thing that has ever happened is i drove my 5.5 tonne excavator over an impact driver on hard clay. It still worked until i took the battery out to charge and the casing fell apart without the battery to hold it together.
Had one one on here myself for repair with the exact same problem. Drove over by a digger. The casing is not expensive and very easy to replace.
As long asnthe motor still works, they are well worth fixing
and like you mentioned "Makita, Built to last" this is the reason i have gone back to Makita with my drills. eventually all my tools will be going to Makita. Tbh didn't think that grinder would work after the salt water, Amazing that its still working.
I think something like this repair every now and then is a good idea.
I've learnt a lot about the corrosion that occurs, how parts can be swapped out and coatings on boards. Well done Dean!
Just a friendly reminder for anyone else playing with heavily oxidized copper contacts: that greenish goo is both irritant and a wee bit toxic, so remember to wash your hands properly and avoid contact with your eyes, mouth or nose (or your wiener if you have to go pee, unless you fancy a burning sensations down there for the next couple of days).
I use a grinder like this to cut tiles. And I'm surprised it still works, because it got wet many times
What a guy 👌👍👀
It deserves new bearings and more clean-up
He will change bearings just for test he didn't
Absolutely fantastic what more can you say.
My Dad used to say... if you buy well, you buy once, if you buy cheap, you buy twice.
Before drying out, a rinse with warm soapy water, and lastly with deionized water in ultra sonic cleaner if available. Rinse the switches and circuit boards, out with contact cleaner to neutralise any salt. Buff the motors, stator and magnets with wool wire or light sand paper to take away the suface corrosion then coat with any type of oil or rust inhibitor product. Even wipe with WD40 would help
Another great video Dean, happy I bought this makita grinder 😂
And that's why you buy a quality tool that have sealed controllers and good confirmal coating on everything else, where possible.
I have to say Makita are the Best tools to have.
A tribute to Makita and you.
Wow ... if I was the customer I would be extremely grateful !! Hope you got a drink out of it 😊
I’ve saved a few power tools like this. Now that you know it works, replace the bearings, clean the machine parts in your parts washer and then soak them overnight in Evapo-Rust. It will be like a new unit!
Good "resurection"! Thanks for the looksee.
Awesome Makita 👌
Awesome, did you go back and change those bearings? Love the videos!
This was exactly my question too. After having done an amazing salvage on this tool, she deserves some fresh bearings!
I have always preferred makita
Mighty Dean, best video in a while, helps that I like Makita anyways tho!! Cheers for all your content 👌
I love this channel.. thanks for another video.
I would feel so chuffed if I had pulled off the miracle you did. Bet the customer was happy with the fix.
❤ Makita
That man is smart because he didn't put the battery in to test he sent it to the shop for repair
I will change my power tools to Makita. Currently I have a zoo of different brands but this was impressive.
Yet another excellent repair. Very well done
She didn't sound too bad either. Great fix Dean.
Just incredible. Well done
You're a magician
Makes me want get some Mikita now
Davy Jones' Grinder⚓ Very Impressive
Good work Dean!
Nice work .amazing result
I think that salt will keep on corroding unless all the parts are soaked in several changes of pure water, cheers
Great job
Wow, incredibile brand.
An incredible salvage, and an incredible brand.
What can you say but......... WOW!
Impressive job anyhow. And nice to see that the only parts that needed replacing only did so because there easily replaceable. Had all the connections been potted they might've survived but then they'd be harder to replace it they were too fail
👍👍
Good job!
I mostly buy Dewalt and Milwaukee stuff, but I know Makita makes some of the toughest tools. It's crazy how fast salt water can eat through coper.
That copper paste... I had no idea this is what happens!
Electrolysis.
Impressive! Good job.
job well done❤
The green substance that is produced by galvanic corrosion, especially in salt water, is copper hydroxide.
When you get water into one of your battery operated electric devices rule number one is to remove all batteries as quickly as possible. This will remove the main source of galvanic corrosion.
Of course, this is not on top of your priority list when you are onboard a sinking fishing boat.
Rule number two is to open up the device in order to get out as much water as possible. If the water is salty you should rinse several times with pure water. To help the water out you can use compressed air and heating to a temperature that the device can tolerate.
That's impressive
That is amazing. You should put your business address on the end of your videos; when I've tools that want repaired, you'd pick up a customer.
The grinder survives hopefully the occupants of the boat are ok.
Very nice 👌
Pleased i bought a makita when my old grinder packed in fsntastic how that worked after been in salt water 👍👍
Hey Dean
I've had pretty good luck doing a short soak/wash in 90% isopropyl alcohol then let air dry sucks alot of the moisture out of everything
Love the videos cheers

I confess i'm a bit irritated he let the salt water DRY and then NOT EVEN TRY TO WASH IT OFF before trying to fix it. it'll keep corroding the poor tool.
@@CrudeBuster as he said in another comment, he didn't expect it to run.
@@AlexKallwell, leaving something covered in salt water dry certainly won't help. he barely cleaned the stator's screws, as if the salt wouldn't make it rust even worse. sometimes i understand he doesn't want to waste time but damn. leaving something to rust filled with salt water then coming back and not cleaning to attest brand quality is insane.
That's a good tip. Thanks for that
guys this isnt the US, services have actual warranty in europe, if the grinder fails again the costumer will bring it back and Dean will repair it no questions asked.
Brilliant, besides a Bosch sds and grinders, an old de Walt router and a Festool track saw, all my tools are Makita….planers, impacts, drills, sanders, router, nut gun, saws, torch etc and although not all perfect, very very good especially for the money. I will always buy Makita products.
Well done
Try throwing that thing in a dishwasher next time. I've done that hundreds of times with electrical - electronic components over the years. Once thoroughly dried they are safe to reassemble.
Super impressive work and tool - I went over to Makita a couple of years ago from Dewalt. No comparison- love the Makita stuff 👌🏻🍺🏴
Why did fishermen need a grinder? Were the fish frozen already?
Depends on what he was fishing for if he was going after crab or lobster perhaps for the cages otherwise yeah idk tbh
Just out of curiosity here, would you be changing out the bearings since the machine is working again?
Customer has lifted it again now. If they get any worst he can drop it back in.
@@deandohertygreaser cool 👍
there was obviously a battery on that when it had a bath as electrolisis has eaten the copper that had power on it but the field coils are fine
the legend says hilti would work underwater too=)))
Ever tried soaking in vinegar to remove the corrosion? Works for me.
Ultrasonic cleaner very handy for stuff like this.
As a diver just an FYI, if you ever drop anything in salt water get it into fresh as soon as possible. You may save it otherwise just eats itself
Imagine if it was a milwacky with a non coated circuit board.
The only thing salvageable would be the plastic clamshell
I prefer first to clean with the fresh water and then to let it dry.
What are you even talking about? Salt water(with vinegar) cleans them. kek
Luv ur vids, dude. So amazed. Hello from Illinois, USA.
Shirley they had tools like these to build the pyramids
Did you lubricate the bearings?
I couldn't tell, were those wires pre-tinned? If not, I'd be shocked if they don't start corroding over time. We have that problem with boat trailer lights that go in salt water. Once there is a nick/cut in the insulation, its only a matter of time before the entire line starts turning green.
IF you are bored, you can try to polish those bearings. Something we do in salt water fishing reels, take out the bearing, take off the shields and run it at HIGH RPM and dunk it in acetone. Over and over until all the balls are polished and all the rust/grease is gone/smooth. Then repack and use again.
Just like timex. Takes the lickin' keeps on tickin.😊
Guessing that seawater around all of the components, mechanical and electrical would cause many more problems farther down the road.
Do you use an UltraSound Bath to deep clean electricals? Maybe that would clean out all of the salts present in seawater.
Do you think the corrosion happed so quickly because there was a battery attached? Causing and electrolysis effect?
with a tool like this that has had salt water immersion its a good idea to wash it out with deionised water and then dry out and repair the deposited salt in the windings will cause failure over time
👍
I always thought copper was non corrosive. Surprised to see the copper wiring eaten away. I guess its the salt water.
While it was still wet, why did you didn't not rinse it off with fresh water to get rid of the salt. I thought that would be the obvious thing to do, before drying it out to do the repair, you couldn't do anymore damage than was already done, just my opinion 👍
That short white cable on the switch with the blue crimp connectors didn't look very OEM. Was it?
The salt is still there, and a little moisture it will start again! Maybe 🤔. But Nice work man!
They should've washed the b'jaysus out of it with De-Ionised water as soon as they retrieved it.
Just you and I,...
Wouldn't it have made more sense to clean it before the salt dried in all the nooks and crannies?
To be honest, I wasn't expecting it to still run
Even keep swimming pool acid containers away from your garage or work place.😮
It's a problem when staying close to the sea coast also. I rather stay far away because I love my tools too much!!!😅
What is the quality of the Makita G-series like? I believe they use a different battery and are aimed more at the DIY market.
Basic
@@deandohertygreaser still repairable and durable though? I mean could you do better for the same money elsewhere?
@@UnCoolDad Forget about it, totally not worth it. It is much better to get 12v line bl drill
"In next video we will be fixing a sunken boat".
I'd give the owner of that tool the battery connector too, if he got the 3 year warranty and serial numbers will mismatch, he got a proof its just been fixed.
What's the torque like on Makita grinders? I've got a cheap 240v Ryobi (I think) and when you press the switch it almost jumps out of your hand.
They have a soft start so they won't jump
@@riba2233 Cheers. I didn't think it was right compared to better makes. I suppose that's what you get for buying cheap shit. It did me in a pinch but it's time for an upgrade. 🙂
Tools starting full speed like that wears faster because going from 0 to 100 in a snap kicks the mechanic in the ass hard.
Tell me about it. @@thibaultmerlin 🙄
Great video Dean. I recon most repair men would have binned that grinder.
I’m willing to bet that had you invested the time into the corroded leads you could very well have saved those as well… but not really worth it when you had a good used part at your disposal
If it was mine i would just sell on ebay as not working and buy another.Most of your vids i would do the same.Most of these tools are not worth bothering with.The people who send these tools into you must be tighter than a Scotchman.🤔
Most contractors will have a few alternative tools so they will be using those - I get the impression some of his customers build up a box of broken tools and bring them in before their other tools break. I understand there is a small charge for looking at a tool (5 Euros I heard on another video - about $6 approx) with a fix attracting the hourly rate plus parts so why not get it looked at ? It beats taking time to list, package and post tools - you can do that if it comes back as unrepairable.
That's a Jesus grinder. It came back from the dead.
Buy a new one
