You can fill in one or both of these fields. If you fill in both, the MotoWizard will consider only exactly that size propeller. If you fill in only one field, that measurement will be restricted but the other will not. For example, if you select Specific Size and select a diameter of 10 inches but leave the Pitch field blank, the MotoWizard can consider various 10 inch diameter propellers such as 10x5, 10x6, 10x7, and so on (this can be handy when you're trying to choose a propeller that looks right on a scale model).

Battery Options On the Battery options page, you can choose the type of batteries that you want the MotoWizard to consider, or specify exactly the battery you want to use.
The Prop Protector cut the rope cleanly, and all the netting. It didn’t shred the netting but cut through it, dividing it in two, and would prevent your boat being anchored by a long length. When the polytarp was left to drift into the prop, it tended to get caught on the blades and just swirled around, but as soon as a slight amount of tension was applied, it was cut through. However, it wasn’t shredded and sometimes remained on the blades, which would reduce thrust. In practice, a large sheet would possibly apply enough drag to make the cutter work. It couldn’t cut any of the wires, though. The netting and smaller diameter ropes could sometimes be drawn down into the gap between the cutter and the P-bracket but reversing tended to loosen this.
One question we get all the time is what do I need to do to keep my stainless or aluminum prop in optimum running condition. Other than not hitting something in the water, there is really not much to do. We always recommend removing the prop for overwintering, but that is to protect against theft and from someone hitting their shins on the prop blades when they get too close to your boat! General surface cleaning can be done to stainless if you want to maintain it's like-new shine, but even that is not necessary, A shiny prop is not measurably faster than one a little dulled by use. But it is critical any edge damage, dings, gouges, or bending of the blades be brought to the attention of a local prop repair specialist immediately. They have the tools and expertise to get your prop back in optimal condition. They are not so busy in the off season, so taking that prop for repair after your boat is tucked away is the perfect time to keep a local craftsman busy during the winter.
