I just purchased a 20' pontoon with a 40 hp mercury 4 stroke. However there is a lake I would like to use quite often to fish where the max hp allowed on the lake is 10hp. I already have a 9.9 Evenrude Therefore, I would like to mount it on the pontoon for those occasions. Is there a bracket I could purchase to andmount on the pontoon that will accomidate the 9.9 hp when needed if so how is it mounted and where can I get one?
