Reply To: Impeller for Brooklure 5 HP Model 230-51-5D

There are manuals at http://www.richardlpaquette.ca/vikingmanuals.htm

The Factory Service manual:
http://www.richardlpaquette.ca/GaleProducts1951-1963ServiceManual.pdf

Says your model number crosses to Gale Model 5D10
This Viking parts manual should cover the internals (but not the decorative bits):
http://www.richardlpaquette.ca/5D10V%20Parts%20manual.PDF

Which shows it as as a model with Forward and Neutral (based on the Johnson TN series), which uses a vaned impeller.

This page describes how to adapt a currently available impeller to the Johnson TN:

I’ve never owned any of the models with this lower unit, but I’ve seen many warnings to drain the oil before removing the lower unit, unless you don’t mind oil all over the place!
