Eight.3 Wakesurf Shaper w/ 1in & 2in Boat Shims

wke3sha12sbsh17
The shim is a simple attachment between the Wakesurf Sharper and a boat's hull. Every hull shape is different - some are mostly flat and don't require a shim. Others have a step hull and require a 1" shim - other boats have a more pronounced step and need a 2" shim, while in some cases you might need both shims to make a 3" gap between the hull and your Wakesurf Sharper. For installation - Eight.3 recommend the Wakesurf Sharper is 80% subgmerged when boat is properly weighted and as close to the stern as you hull will allow.
