Hello William,

I'm afraid we are not Mercury dealers and aren't able to special order them. All we can suggest is to contact Mercury directly.

Sorry we could not help.

Will this fully function with 2006 Verados
Question by: Shane Harris on Dec 9, 2022, 10:18 AM
Hello Shane,

I'm afraid we do not know. Not being dealers, we aren't able to cross reference it back to 2006 motors. About all we can suggest is to contact Mercury directly and give them their kit number (4939862) and control number (87775A20) They may even have a conversion kit if it doesn't completely match up to your Verado.

Sorry we could not help more.

Hi Paul,

I am very sorry, but we are not dealers/distributors and are unable to cross reference controls to specific motors. About all we can suggest is to contact a Cummins dealer to get a recommendation.

Hello Bob,

Honestly, we aren't the people to ask. We purchase surplus and overstocks, so we don't actually service boats and can't really trouble shoot issues like that. About all we can suggest is to contact a Mercury dealer.

Sorry we could not help.

I am trying to buy only the handles. Mine have corrosion inside the handles. The base looks perfect and like new. Do you sell only the handles? Thanks
Question by: Marcelo B Lopes on Aug 10, 2022, 2:50 PM
Hello Marcelo,

Unfortunately, we do not currently have the handles by themselves, and they aren't something we can source or order. All we can recommend is to contact a Mercury dealer.
