I recently purchased a 17' sea class TDB to use mainly on the Columbia and larger bays or OR and WA. My 14' barnegat just wasn't cut out for the rough days and long hauls. The new boat does not have a motor and I was hoping to get some opinions on a 50 or 60 hp 4 stroke. The boat is rated for a 60 and more seems better for this big water. Any thoughts?
