You can't have your cake and eat it too! That said since you need the low
end pull for all the fun then drop pitch to 21 but keep an eye on your RPM for them speed runs. You should have no worries running that 4.3 to 4800. I had a 5.7 which was in the same 4200-4600 but propped for 4900rpm, 10 years later and still no engine problems. "Steve" wrote in message ... I'm looking for help in selecting a new prop. I'm currently running a 14 1/4x 23p 3 blade that came on the boat from the factory. The boat is a 2003 Larson SEI 190 (open bow runabout) with a 4.3 volvo sx sterndrive. It will turn this prop 4600 rpms (4200-4600 reccomended by volvo at WOT) and 49 mph according to speedometer at WOT. This summer we have started doing alot of slalom skiing. Needless to say it is a bit lacking on power to pull up a 200# plus skier . I have been looking at 4 and 5 blade props but am at a loss as to what size should work best for me. Also is there a big trade off for power to loss of top end? I need something that will be a good all around prop as we do alot of tubing and wakeboarding as well as just cruising around the lake. I do not have a local dealer that will let me try out different sizes. I'm not afraid to spend some $ on a good prop, but dont want to experiment with sizes at the prices of these props. Thanks for any help Steve |
