Re: More Performance Possible?
I want you to understand all of the theory I am using to try and make your boat ride higher in the stern and thus plane easier. I am still waiting on the call from Volvo, I will call them today.
Finding the BEST prop for your boat would require trying many props to get the best performance we could out of it.
My intentions are not to find the BEST prop, just a prop that helps bring the stern up, that is our problem, with the power that you have available and the hull form that you have it makes lifting the stern a very important consideration in order to see any improvement in lower planing speeds and cruising.
This is a science to a certain degree, that is why i have all of the different formulas that I use to try and prop a boat correctly, not always the BEST prop, but a much better prop than what is on there now.
BUT, then it becomes an ART and NOT science, because of all of the different types of blade geometry available and hardly any manufacturers will tell you anything about the blade geometry of their props. That way they can get you to buy three or four of them instead of just the basic two you need. Normally you need two props, one for normal circumstances and another for heavy loads and to be used as a spare in emergencies.
I can't tell you how many arguments I have had with manufacturers not wanting to give me the blade geometry of their props, like it is a trade secret or something, and they justify it by saying it is. That is a lie because any good prop shop can tell you every detail involved with the blade geometry of a specific prop. The reason they don't want that information available to the public, they won't even give that information to dealers so they can sell more props. That is why people like Dhadley and Walleyehed are so good at picking the correct props for boats, because they have extensive backgrounds in actually using so many different props and over the years have gained tremendous knowledge of what prop works on what boat and motor combination, be it a stern drive or an outboard.
I hope this better explains what I try to do here, 99% of the people who come here are not looking for the absolute maximum potential from their boat, and aren't willing to spend the time and money required to do that as well. I feel my job here is to find a much better prop than what they have on their boat at this time, I do not have the background in prop testing like Dale and Kenny do and never will. Any time they make a recommendation for a prop for a boat, people ought to listen very hard, as Tailgunner once told me, before I knew about their qualifications.
