We just bought a used Arima Sea Chaser and it came with downrigger mounting bases but no downriggers. I'm trying to identify what brand/type of downrigger is used on these bases.

Each base is a smooth/flat 5" square of hard black plastic that is about 1/4' thick. They are mounted to the boat with four countersunk screws in each corner. Just inboard of these screws are 4 more screw "inserts" which appear to be where the downrigger attaches to the base.

That's all there is to them. No identifying marks or lettering. No grooves or rails for sliding on a downrigger like some brands have.

Does anyone have any idea what brand of downrigger these might be for?


Thank you!
