Suzuki o/b, Smiths log

[Guest]

I have an 8hp Suzuki o/b on my Coronado 25, I need to reprop to give me some 'brakes', any experience out there? Plus I now own a KH/SM510 speedo/log (manufactured by Smiths Industries) minus hull fitting. Wiring is + and - plus two grey wires. What do I need to get the thing working?
