We recently acquired the inventory of a large marine parts distributor. May have cosmetic blemishes from storage.

The STW ESX2-4 is a rugged, freely programmable electronic control unit designed for demanding mobile and marine applications. These modules support custom control strategies and can be reprogrammed to meet specific system requirements. New or previously configured units can be erased and reprogrammed, allowing integration into custom applications. In some cases, OEM-supplied firmware may be locked, but a full reflash with new software is still possible.

Please Note: This unit may require reprogramming before use and due to the complexity we are unable to conduct a full bench test to verify its complete functionality. Therefore, we offer the buyer a 30-day period to thoroughly test the item. If it does not function properly during this time, they can return it for a full refund.

All items sold at Max Marine Outlet come as you see in the pictures provided, with only the parts and accessories stated in the description section named “What’s Included”. IF YOU DO NOT SEE SOMETHING YOU EXPECT TO BE INCLUDED IN THE DESCRIPTION WE PROVIDE, IT WILL NOT BE INCLUDED. Read all descriptions thoroughly. There are times when a display is used only to show the item being sold is functional and working properly. In this case, these displays are not included. If you have any questions feel free to reach out. We always want to be transparent with our customers and fully disclose any information regarding the products we sell.
