Konrad 520's in classifieds
In regards to the classifed listing of the 520 Konrad drive units.

The Konrad 520 is NOT a direct replacement for the Merc TRS. The 520 is a commercial/work boat drive with a much deeper lower gear housing. They do not run standard Bravo style props, they are built to run props to 20" diameter. Also, the upper input shaft will not work on a TRS application.
The 520 can be made to interchange with the old TR drive (typically found on older houseboats/cruisers) as long as the upper input shaft is swapped out for the correct application.

The 540 lower will bolt up to the 520 but the gear ratio of these 520's is 1.43:1. If you bolted up the 540 lower to this particular upper, you would have a 1.21:1 ratio. The upper input shaft would also have to be swapped out to accomodate the TRS transmission.
Feel free to call me direct for more info.
