Thread: repowering pontoon dinghy

iv got a boat lined up a 4m pontoon dinghy and will get a new outboard for it i plan on using it for everything from lake and sea fishing and diving and want to be able to use it for travelling around places like the Marlborough sounds etc. i see a lot of boats this size have options for 15-50 hp motors on them is it better to go bigger than you think so when loaded up with diving or camping gear etc and to have the extra grunt for getting back when at sea or a travelling a long way but then how big is too big? thanks in advance for any tips.
