The power egg as an interchangeable engine mounting

What is the power egg?

An engine mounting described as a common fit for different engines; the discussion does not establish whether the Mosquito could use it.

The power egg is described as a common engine fit that could accept different engines on an aircraft. Its name is linked to an oval or egg-shaped mounting. The example offered is changing an aircraft from Merlin to Hercules engines when it has a suitable installation. There is explicit uncertainty about whether the Mosquito could use this arrangement. The explanation therefore supports the general mounting concept without establishing that the proposed Sea Mosquito could make that engine swap.
