We have done two 2-month cruises in the Bahamas with a 8ft air floor Walker Bay and a 2hp Mariner (yamaha) 2 stroke motor
Pro - the light weight 2hp is GREAT. Super easy to store. I can easily lift
it up to the rail for storage
myself, or even store below in the deep lazarette. It sips the fuel
. Always always always runs & starts. Simple mechanics: no transmission
and gears - if you want to go backwards the motor
swivels 180 degrees. a replacement plastic prop costs $30. Easy/simple to maintain.
Con - it's slow. You just putter putter through the water. Most days, that's fine, but occasionally, it's very very difficult. For example, the run from the anchorage at Monument Bay (Georgetown) to the dingy dock
takes 30 to 40 minutes (instead of 5). One time near Stanial Cay we ALMOST couldn't make any forward progress against the strong ebb tide. Going offshore
to dive/fish>>forget about it.
For us, we're fine with the 2hp, but we've got our eye open for a killer deal on a 4-6hp 2 stroke used somewhere. If we find that, we'll probably upgrade someday.
But really, the 2hp is perfectly functional and serviceable. Key words: Simple is good!
