Bert, Thanks for the link! It seems very interesting! Anyway, on the PSModel web ( http://www.atljsoft.com/HTML_Help/Index.aspx ) one can find...
Hi guys, Is there any empirical equation for calculating how much the propeller pitch should be decreased or increased to fit the target RPM?...
Hi guys, Does anybody have some experience with company named ATLJSoft that sells propeller selection software "PSModel"?! I tried to contact...
Finally some developments Hi guys! I feel responsable to inform you about the project developments. I made some further test, made...

Producer of the boat in subject told me that if cavitation was my problem than the engine would go to overspeed. But my engine is not reaching...
Do anyone have same experiance about portable laser tachometers? I would like to buy one for measuring the props shafts RPM on different boats?...
well, I said from beginning that the boat is not hard chine...OK my apologise, I shouldn´t use Savitsky as method. I start from beginning. I know...
further...gear ratio is exact 2,0 :1 as far as I see...the great deal is to define the exact thrust needed for each speed but do you have some...
well these data are 100% sure: my engine develop max. 220hp @ 3600...this is an older type of engine than those ones on the vm site. I have all...
that`s what I call brain storming...thank you Daiquiri... as Daiquiri made me attention on probably wrong thrust required made following:...
Can anyone check if I`m going on right way... Situation: The three blades prop installed 17"x23" runing on 220hp@1800RPM and with B.A.R.0,73...
sorry...forgot to mention two more things: gear ratio is 2:1 and max. prop diam. is 17˝
well I can`t say I`m surprised about the discussion arrised from my questions as I had clear view about the knowledge of members of this...
tnx Gonzo, the thing is that I would like to listen from you your experience about the way of accurate prediction of cavitation. Is this from...
look inside: Boat mechanical system handbook by D.Gerr or try to find some of digital back issue of Professional Boat Builder good luck
Hi guys, I`m calculating the right prop for a boat of my friend. The boat`s performance is quite bad in comparision to a boatbuilder chart and...
