I have a 1991 Sea Ray 220DA LTD with a 4.3 LX engine. I need to purchase a new prop. I plan to go with a 14 x 19. Which one would be better for general performance, a cupped or uncupped aluminum prop. Thanks Tom
Hey Riverman,
Check this out: http://turningpointpropellers.com/propellers_101_cm.htm I own a turning point prop 19p on my 00' 180BR 3.0 and a Vengeance 21p by Merc Marine on my 97' 230BR 7.4L. Both are stainless, cupped and raked. I think you generally get better performance out of a cupped prop. In fact I don't think I have seen an uncupped prop on a boat in a long time. Factory Alum props are even cupped. Unless you are really trying to save $ or there is some other factaor, a SS prop will also last longer as it is nearly impervious to the small dings and whatnot.
