Kmoose,
I've read everything you've posted regarding your boat, the 300 Zuke and your prop selection. Many thanks for your contributions. I have the same boat although a few differences in our restorations. I have a hard top and upper station but my fuel tank is 115 gallons so the net difference in weight may not be that much more.
I am about to order my 300 Suzuki and I am struggling with how to ensure I have the best prop. I hate to spend the money on a new Powertech prop only to find out I should have ordered something else from them. I see you went with the LFS 16 x 18 in a 3-blade but you also said it was a bit "under propped". By under propped, I believe you are saying that you could have used a bit more pitch (18.5 possibly??). Is this correct? If my boat is slightly heavier than yours, I would assume that the 16 x 18 would be just about right. What are your thoughts?
Why did you not go with a 4-blade?
I am going to call Powertech this week and see what they recommend. I am hopeful they can recommend a prop to me once I provide them with the details of my boat.
Here is a pic of my boat. I have the Hermco single bracket.
(I know my trim tabs are too far inboard but I'm gonna let it ride and see if it is manageable before cutting holes in my bracket.)
