For those seeking a more comprehensive fall tune-up, there are several shop-based services worth considering. These can include things like removing and reinstalling the drive unit (plus greasing where needed), swapping out the water pump impeller, and giving the hull a thorough cleaning to tackle algae buildup. Technicians can also remove pesky zebra mussels before they become a bigger headache. And if you want your vessel to weather the winter in style, professional shrink wrapping is available to add an extra layer of protection until spring.
