You should not have a problem with the splash well voids and water. All 210/215's made since June 1st 2005 until now have a new rotomolded block that almost completely fills the void under the splashwell plates. Any water that does get by the plates is limited to a cup full or so. For anyone that has a 210/215 made prior to June 2005 you can contact your dealer to receive the new inserts and a tube of RULE Elastomeric for $20.00. Check out post #41 in the
this thread. You can also read about Osprey Vic's modification to provide access rather than using the inserts.
