Kubota V2003 Beta Marine rear crank seal oil leak repair

While servicing the main engine on London water bus of Paddington, the Water Bus Milton. Last year I noticed a serious oil leak at the rear while carrying out a normal service and inspection. I was asked to return to assess the issue and make repairs as was necessary.
