It’s a thought...... I’m going to get my number two prop re-furbished and re-pitched a bit, they will try for 23” but no promises yet because it all depends on what its current pitch truly is. look forward to seeing what effect that has
Equally I have a very heavy right ear so might try driving facing backwards to see if that helps

Came across Motor Boat Monthly's October edition and there is a useful article in the installation of these units on a single outdrive 27" Bayliner. A follow up report will, errrr, follow later!
Should be interesting as this article is quite good.
