This is a used exhaust ring coupler off of a Wave Venture 1100. It might fit other models but that's up to the buyer to confirm.  It's clean and in great shape, came off of a fresh water only ski.  This has the original factory clamps with the edges that won't dig in and tear the coupler. Shipping is to the lower 48 states only. Part# 62T-14625-00-00 for the coupler.
