Anybody that tells you a 2 hp will push you into an inlet in a falling tide is nuts. If you are taking that boat offshore get the 3 gallon auxilliary gas tank. It sucks to run out of fuel
at the inlet. If you have to refuel, over 75% of the gas will spill in boat, on water, on your hands, etc. A 4 hp will push you but a 6hp will get you in quicker without having to run it flat out. The 6hp also has a generator kit to charge your bat. Most inlets are narrow with flows in the 3 to 5 mph. Getting inside while going under a bridge is a harrowing experience with motorboaters going every which way at 1o to 12 mph and dragging a 3 to 4' wake.
Make it a point to disconnect the fuel line
and run motor on fresh water muffs until it runs out of gas and conks out. Do not use fuel
from Marinas but buy the fuel
where you fuel up your car. If the gas is 3 mos old pour it into your automobile fuel tank. Get fresh gas.The day you forget to run the engine dry will be the beginning of problems with it. Disregard the nuts worried about wear on motor.
The issue is not getting around the Marina. It's getting through a tidal region, under a bridge, usually in a falling tide, against a 20 knot wind with boats of all kind trying to go through at the same time. Most of them dragging a 4' wake behind. I know, I have to face it all the time.
