Boat props that is (not airplane props). Some may remember my boat thread a couple/three weeks ago. Well, I bought it with bad props as that was part of the reason why I got such a good deal on it. The seller had gotten a quote for $900 to swap them out which would have involved pulling it out of the water and trailering it to them (in a trailer I don't have yet). So, I put my wrenching skills to work. Ordered new props online for $500 and swapped them out today while the boat was still in the water. My boat uses dual counter rotating props so there are no torque effects to make the boat favor turning to one side. Makes for a smooth ride, but a bit more of a pain to replace. Also cleaned the air filter, put on a new alternator belt and adjusted the carb idle setting. Significant improvement! Here are the old props. Yep, pretty danged shot!
