I have a 1990 Sea Nymph pontoon model number on the title says 2019snb and on the side of the boat is sn200. I'm wanting to upgrade the outboard from a 25hp Johnson but I cant read what the boat is rated for. I've tried to search for a web address for sea Nymph with no luck and I've search...
I recently purchased a used 20' pontoon with a 25 hp johnson that has some running problems. What I'm needing to know is that if I upgrade engines to around a 50 hp do I need to change the controls as long as I stay with a johnson or evinrude? :confused:
