|Hi, I am from Spain. I have a searay 180 I/O, I am ready to change the 3-blade prop to a 4-blade prop for better holding. The question is that I donīt know what pitch I need. |
I put about 600lbs of weight in the boat. The engine is a 4,3L alpha one. The propeller I want is the alpha 4-blade, it comes in 16, 18 or 20'' pitch. Which ones is better?
thanks and sorry for my bad english
|start with the 18. the 16 would pull out of the hole better, but top speed might only be 30 mph.|
|I had that same boat and motor. the 18 is what I ran and was a good choice. holding speed was still tough. the 16 imo would not be a good all around blade. the 18 should be enough|
