Bro are you running a 3 or 4 blade prop? I’m going to run a 4 blade small diameter with a ton of pitch.
Badbagger said:Thanks and running a 4 blade 13 x 17 Dave. Actually that is what should put me very close. However, when the engine is installed they'll use some of their test props. With the Etec engines they need to be propped to the optimum RPM so we'll see what the sea trial turns up. Using a Rogue prop by Evinrude. It also has an advantage of having a smaller hub which allows exhaust gas to flow over the blades & retains RPM's like a 3 blade prop. Most 4 bladers are hard to turn & lose RPM's compared with the equivilant pitch 3 blade prop. This is not an issue with the Rogue. They hang on well in rough water & can be raised up high on the transom which improves efficiency.
