Thanks, rcgldr. That was where I originally took my question, however, I wasn't satisfied with the "rules of thumb" they relied on as they've failed me in the past. Was hoping to basically average the results of the theoretical and heuristic approach as my starting point. With respect to...

Try them for a recommendation, that is... not for the data. Cheers

Thanks, SteamKing. I misread your post, indeed. In fact, you've answered the question. Despite all the figures I have at my disposal, the most important ones related to the prop are out of reach. I'll try the prop manufacturer or, if that fails, go with tried and true trial and error...

Thanks to both... I'm no physicist so might be barking up wrong tree... I am, however, an economist so always looking for an equilibrium, fake or otherwise. If I'm getting carried away here, just let me know... Steamking: I tried this angle, but the engine is out of production and couldn't...

Last thing... not spamming this... If there's some optimal relationship to shoot for between engine torque and some other metric... say thrust which I didn't calculate here... then I can introduce pitch as a variable with the book ends being min of 0" pitch and max of 25" pitch (from observed...

I'm happy to share the spreadsheet, if helpful. The calcs are all audited and confirmed.

All, Turning to the experts with a boat problem I'm trying to solve. Specifically, I'm in the process of changing the gear reduction of the transmission on my boat and will need to get a new set of propellers with a different pitch. The old set up worked just ok... I tested different...
