That looks nice! hasn't even got any chips on the prop! Good find!
Just be careful lifting the thing. Honda's are the heaviest you could have bought!
Actually, just checked against the Mariners and the Honda you've got is 47KG dry, the Mariner is 52KG, which is surprising.
You're definitely going to need two people to lift that safely.
Get a trailer. your body will severely thank you and boating will be a LOT more enjoyable.
And make sure you run it in a bucket and are completely happy with all the controls before you go to sea.
Things to test:
Starting and stopping when both hot and cold
Kill cord both works and you know how to refit and restart the engine
Any points on the throttle that it's a bit non-perfect. Some of the smaller 4 strokes are fine going from neutral idle to in gear idle but if you accelerate too quickly will stall.
how the tilt system works including all the tilt and trim points and how to get it back down again.
