[QUOTE="MrGiggles, post: 504588, member: 22613"] The driveshaft (which turns the water pump), is directly coupled to the powerhead. No amount of wind would be able to rotate the powerhead via the prop. The gearcase is splash lubed, if anything is turning there is lubrication, engine running or not. In theory, every revolution the prop makes creates wear, but with essentially no load on the components, it is negligible at best. In a perfect scenario (the motor hangs close to vertical on the trailer, and the wind was unobstructed on the way to the prop), I could see the prop getting some speed going and I wouldn't want that, but it's never been a problem on my setup, nor have I ever seen a prop on the highway turning more than a few RPM. As mentioned, it's a CYA thing from manufacturers. Many manufacturers recommend reverse over forward due to the overrunning clutch in forward gear, the prop can ratchet without turning the driveshaft. Ever have a motor stall underway and hear click-click-click as the boat slows down? That's the clutch doing it's job, it's there to prevent swamping from the engine braking if you let off the throttle too quickly. There is no ratchet in reverse, prop is locked to the powerhead in both directions. [/QUOTE]
