The Konrad 520 is getting removed and crated for sale. I had 0 issues with it, it is a great drive, it needs some prep, prime and paint in some areas on the leg where there has been some minor surface corrosion.
Bringing in a new Konrad 560 leg to replace it. NOTE: these drives have two major halves, the transom kit and the leg. I'm keeping my original transom kit which includes a lot of stuff like the steering, the tilt pump, cylinders, the drive shaft etc. That is the complicated stuff to install and I just totally rebuilt my steering cylinder + setup.
Replacing the leg is straightforward, 6 bolts and the seal and it is off.
The 560 is 4" less draft and more efficient. It is duel conter-rotating prop which is optimal for the diesel RPM ranges. It should handle the additional torque with ease.
I really can't wait. I had two prop ranges we speced out. 1 would bring top speed to almost 50 mph, the other brings top speed to 45 mph but is much better for the operation of the boat in bad seas states and heavy loads. I ended up going with the lower pitched, lower top speed prop which is a 25 and 26 pitch, averaging 25.5 pitch.
