I am going to buy a raft soon (my first) and was wondering if there would be a big differnce in places I could go with a 3 or 4hp vs a 10hp outboard?

The rafts that can handle a 10hp are way more expensive.

I want to use the raft for fishing (maybe some hunting too) in lakes (rowing in some) and rivers either drifting or motoring.

I've got about a grand saved up right now, and I want to at least buy the raft now(minus the engine mostly likely).
