I posted a question about what prop size is right for my boat. Everyone is telling me to try one and check my w.o.t. acccording to the service manual. My boat doesn't have a tach and I don't want to put one one cause it's one less electrical connection i don't have to maintain and my boat is a slow fishing boat. How do people with tachs buy props. Do they guess which one they need, buy it, try it on the boat, find out it's above or below the recommended w.o.t. on the tach and then return it, buy another and repeat the process? I can only afford to get the right prop the first time cause if i use it my boat store won't take it back. When you buy a motor new doesn't it come with a prop already on it? There has got to be a way to get the correct prop without a tach and with out trying it first.
