Going to attempt to remove my engine with the use of a chainblock and the boom.. with the boat in the water.

 

Swing the boom out over the side and lower onto finger.

 

Any advice on what/what not to do?

 

Engine is about 140kg.. I think that included the gearbox.

Attach a halyard to the boom where you are lifting the engine from.

There is nothing, absolutely nothing, half so much worth doing, as simply messing about in boats

Get a big friend, or two normal friends to actively balance the boat with their body weight as you swing the boom out over the finger... 

And put some tarps and polythene down to catch any crap that dribbles out of the engine. Have a few wooden blocks ready to prop the engine up to stop it rolling or turning out of control.

This seems like good advice.. thanks!

No problem, and it wont heel the boat that much. You'd get more than a 140kg load on the main in a bit of breeze...

What IT says  :-)

Engines on smaller yachts are not heavier than what your rig should be well able to take.

If you want to be careful, then run your halyards to brace your load.

(like extra stays in line with your lifting angle)

Perhaps run your main Halyard as an extra topping lift.

 

I welded a lug in line on my boom, specifically to lift the engine. Having a centre cockpit with a lifting floor makes it very easy.
