Has anyone tried the Michigan wheel DQX on the Nordic tugs?

With othe boats i have heard that it has an impressive increase in performance.

Sue,

What pitch did you end up with? I have a 28x28 4 blade prop that I can hit slightly over 2600 fully loaded with a 6CTA rated at 420hp.

Tom

A spare prop, as others have said, is a low priority for me, a single prop behind a large keel trawler owner. That said, there's been some very exciting developments in prop design in the past 2 years. Sharrow Engineering are producing a double bladed prop that is up to 15% better in terms of speed, fuel consumption, stability in turns, etc. Worth checking out. Disclaimer: I have no connection to Sharrow.

Hi Tom, it was 28 x 30, now it is 28 x 28.

We have a trawler built in 1964. We’ve travelled poorly charted waters over the last 15 years and guess what? Same prop!
