propeller - 2 or 3 blade
Well, the thing is this. I''ve worked in yacht service, (repair and maintanence) for the past 19 years, and here is the real truth about two bladed props ..... they don''t back down. Now, folks can crack wise about that all they want, but the truth is, 95% of light, minor but annoying bow damage, happens when you are trying to dock and when you put it in reverse, the damn boat won''t slow down or stop unless you race the crap out of the engine. Now, I''m only saying this because it''s my experience. I realize that folks on a mooring don''t dock, because I''ve kept my boat on moorings for years, but you still have to slow and stop to pick up the mooring. Also, unless marinas are different in places I don''t know about, you either back into, or back out of your slip every time you use your boat. These are not idle speculations of how things might be in a fantasy world. It''s how they are. There are many people who are completely sold on two bladed props and have no sense of shortage of their lack of performance. Some even love the folding type and swear they back down fine. They don''t. In all these years of yacht service I have delivered and moved thousands of boats of all different configurations. Two bladed props don''t back down, but that doesn''t mean you can''t adjust and be happy with it. And they do have less propwalk than three bladed. My boat weighs 20,000 pounds and I like a prop that stops it when I''m docking.
