Downrigger mounting plate,

[Craigstruzz]

Hello. I just purchased an 86 searay Seville and am in the market for an electric downrigger. There are holes already drilled from previous owners downrigger spaced four inches on center. I would like to purchase a downrigger with these specs so I don't have to drill new holes. Any recommendations? Thanks

The Cannon swivel bases run 4 inches center of holes.
