About this part
Rubber exhaust bellows referenced to Volvo Penta 3850426 and 3850426-2, and OMC Cobra 3850426, 914036 and 767724 for applicable Volvo Penta SX sterndrives from 1994 and higher and specified OMC Cobra sterndrives. Confirm whether the sterndrive uses an exhaust bellows rather than an exhaust boot before ordering; this is an individual exhaust bellows, not a complete transom service kit.
