I found a replacement AC2W for sale in North Wales. It's been taken out of a salty-type yacht as the owner wants more power. His loss is my gain.
I drove up to Port Dinorwic to collect it the following day.

Snapped: AC2WM shortly after possession is taken


Fitted and running the very next day.

One small problem was a corroded-through oil supply pipe to the front bearing which spurted oil everywhere. This was swapped with the 'spare' from the old engine.
The alternator pulley and belt was a fun swap. The pulley needs to sit behind the pump pulley, getting off the existing pump pulley from the new engine was almost impossible. It ended up coming off in bits, but we had the 'spare' from the old engine :o)

The steps were removed at the same time, won't be needing those anymore!
