The water finally got soft enough to try the DSD. I’m extremely pleased that everything worked and wasn’t really surprised that it was slower than I wanted. Average speed, in still water, is around 13 mph. I was hoping for 6 or 7 mph faster. I had limited the diesel to 3000 rpm so the next time I try it I’ll set the no-load rpm at 3500 and see if it will turn that fast under load. The prop was not surfacing and when I forced it to surface there didn’t seem to be a change in speed. I’m using the 35 hp SD 3 blade prop and it might be too much. Eventually, I hope to try the smaller prop used on the original 23 SD. Noise level and vibration were both very low. I haven’t figured out how to include the short video, but will….. eventually. My worries about the additional weight on the transom appear to be groundless.
