Re: Simpson Davits Maintenance

They are made by a Swedish company. Open up the electrical box in the lazarette and you'll send the company name. Simpson slaps their label on the remote and charges you more. It's a simple RF transmitter, I think. 

That said, my receiver failed and triggered the "up" motion out of the blue. The magnetic stop switch failed too so it just kept pulling up until the wires melted. I disconnected it permanently.

In 2018 I tried to order 2 new remotes for the electric Davits; after many Emails with no reply I called COONEY UK and they quoted something like GBP300 or GBP350 per unit plus shipping but didn’t want to deal directly with retail. My NEW CALEDONIA marine contact tried to order and didn’t get any response either.


I gave up and just use the controls on the Davits.

Hi Scott


Same thing Cooney asked for 7000€ for new manual Davits since they pretended it could not be upgraded to Dyneema. 


So I asked the local yard to do the Dyneema upgrade two years ago  for around 200€. Unfortunately I wasn’t there to see how they did it.


In fact it has worked quite well. 


I learned it was better to leave the lines down with the weights in the middle when tender in use in the water. Quicker and easier to lift back up.


I am still looking for shop manual that would describe the inside and procedures.


Thank s again for your help.

Yes, I changed the wire out to dyneema. Very good upgrade. I think Simpson wanted 4000 GBP for it and it cost me 100 euros to simply change it.


Of course at the end of the davit where the line makes a 90 degree turn, there's a sheave. Perhaps yours is well worn or binding?


To access the motor/gearbox on mine, you just remove the small allen bolts on the forward (in relation to the boat) portion of the davits. On our electric davits, you remove four quite large screws from underneath the arm and the motor/gearbox bracket comes right out. Sadly, I've had to fix it more times than I care to mention.

Hi Scott,

Thanks for your reply. Did you change from wire to dyneema? 

I feel but can t see that one of the sheaves inside has friction that our ordinary weight is not sufficient to overcome.

I can t find a diagram view of the mechanism in our Series 7 Simpson Davits

BTW great information from your social media.

Best regards
