1. Installation may vary according to the following factors: engine mounting height, transom thickness, use of transom savers, tiller bolt location, engine tilt range, and engine size. 2. For center engine drops greater than 3 inches (76 mm), please consult Dometic technical service. 3. Tie Bar length may vary depending on toe in/toe out setup. To allow for toe, add or subtract from your nominal engine center to center distance.
4. Based on recommended engine manufacturer minimum center to center distances. Deviating from these recommendations may require stroke limiting cylinders and/or engine tilt limiting, please consult Dometic technical service. 5. Cylinder’s must be plumbed in parallel only, no series connections. Only exception
is if cylinders are utilizing a liquid tie bar. 6. Maximum drop: ≤ 3 inches (76 mm).
Revision Date: JANUARY 21st 2022
* HC6850 for Honda V6 or where stroke reduction is desired. Yamaha 3.3L engine requires one cylinder per engine. † Mercury multi engine applications may require additional parts, contact Dometic technical support. OXE 300 must use dual cylinder HC6850 for twin engine, no single cylinder option. For triple engine setup two HA6864 bolt kits must be used for center engine. NOTICE! Required for triple engine installs on Mercury Optimax and PROxs and engines with a single tiller hole. May fit other applications, call Dometic technical support for more information.
