Found a way of keeping the motors from corrodng


I have had 4 dives now, 2 in the Bay and 2 in 100+ feet of Pacific ocean water. Even though I ran the Trident in fresh water each time I noticed the motors running rough. So, on board my boat I have an electrical spray made for marine electronics and electrical connectsion. I even used it on my pliers that i use to get hooks out and only had to spray it once and after several years, they still work.
So, before the next two dives in deeper water i took the covers off of the motors and sprayed them with the liquid. No more rough motors and only sprayed them once.
Now as for the results of the dives… I found very it colorful I must say. The rock fish seems to gather around the drone. The Trident performed well. I just have difficulty with the heading. While transending to the bottom the compass heading indicator sometimes just goes in circles. Don’t know why. Stated using a 3 pound weight on a fishing pole tied 30 feet before the Trident to help it get down quicker. It also helped as an anchor and allowed to maneuver better in the currents.
I would think that the gyro they have used has at least 3 or 4 axis so it would be great help if they would put a yaw display along with the pitch.


Can you please share the product name of the “electrical spray”…

I think you are onto a good preventative solution.

Did you still run the trident in freshwater after the dive or just rinse it off?

Saltwater likes to eat everything!

Could you please send a foto to show how far you dismount the central engine. That would be really kind !


Yes you should still run it in fresh water. I am not sure of the name, I will post it next time on the boat.


Did not dismount the motor, just remove the cover and spray it while it is running slow to work the oil in.


I believe the name is Corrosion block

I have a few years old 2.8 and I’ve done tons of dives in salt water. The motors are doing very well I think it’s partly due to always spray food grade silicon on the motors before and after a dive. It displaces the corrosive water.


I was wonder if I should spray the motors before I start flying the trident.

I received it today and I am Stoked! And yes that’s how I speak in real life…

I purchased this product on Amazon.

Should I spray the motors before i start flying the Trident or is this similiar to what is already on the motors and should stick to the marine or food grade silicone.

Cheers Everyone!


New motors are here but might still be good idea to use Corrosion Block and/or Food Grade Silicon spray. I’d prefer the quart bottle & pump spray but those are not on Amazon Prime so shipping to Hawaii is prohibitive. Hopefully the aerosol version will ship …


I have found that a product called Corrosion X is really good at inhibiting corrosion.
