Re: 25 hp prop sliping

Welcome to iboats and please punctuate. <br /><br />If you operate in shallow sandy waters, it's not uncommon for the prop hubs to deteriorate and begin slipping. They're replacable by a prop shop. Maybe your splines are bad on your driveshaft and it's slipping in the crankshaft. But I've only seen that once and it didn't slip, it didn't turn.
