We did it already on our Maramu, lifting off & replacing engine afloat.
A stout piece of timber on top of engine, resting on cockpit side benches & main sheet did the trick once the engine was disconnected from its holding bolts fastenings to the support frame ...
This was the hard part
- one nut on rear aft stb side gave poor access with the famous 1/8th of a turn with open wrench already grinded to enter space betwen batteries compartment & engine base; guess you can expect one of those
- engine base & mountings stuck by grease, & salt & whatever when trying to lift first, high resistance countered using crowbar & wooden block & wedges & sledgehammer (cautious when beating).
- removal of shaft was easy enough (4 bolts & nuts 10mm) then moved by hand; reverse to connect checking alignement respected when reinstating (clock markings on flange helped)
all makes an interesting day of work, & good Opportunity to clean Bottom & repair paint work. Satisfaction when completed - do not forget to check tightening of bolts on support frame after a while running - they come loose unless you Added loctite on threads.
Meanwhile fair winds & Following seas

When we dis this on our Maramu we just put a i-Beam across the (padded) cockpit coaming and then used a lifting tackle off that
It worked well and was very simple
I presume the same would apply for the Mango but i'm not sure if you have the same lifting cockpit floor engine access?
All the best
