Be sure that the threaded rods are bottomed out in the rod ends before tightening the jam nuts against the rod ends. The two threaded rods must be threaded into the center tube far enough so that the threads can be seen through the two inspection holes at either end of the center tube. This determines the maximum extension possible. The minimum centerline distance is 470 mm (18.5 in). Do not tighten the jam nut.
error adjustments June have to be made in order to maximize the performance of the dual engines. 1. Turning the center tube in one direction will create “toe-in,’’ while turning the center tube in the opposite direction will create a “toe-out’’ attitude for the two engines. An 11/16 inch flat has been provided at the center of the center tube to facilitate turning the tube. Always tighten the jam nut against the center tube before doing any performance evaluations. 5. 2. LNOTlCE I I NOTICE I Extending the bar, so you cannot see the threads through the inspection holes, can make the tie bar weak. A weak tie bar can flex and adversely effect steering.
Do not exceed the maximum allowable extension of 749 mm (29.5 in). Grease and place the bushing inserts through the rod eyes. Mount the bar with the bushing heads under the steering plates. The bar can be mounted on top of the steering plates in some applications. Place a flat washer over the 3/8 inch hex head bolt and insert the bolt through the bushing in the rod end from the underside. Thread this bolt into the forward hole on the steering plate found on the front of the engine. Thread the self-locking nut onto the bolt portion that protrudes above the steering plate and tighten securely. ADJUSTMENT Different hull configurations June require slightly different set-up and adjustments.
Some trial and Leaving the jam nuts loose can cause the rod ends to misalign. Misaligned rod ends can adversely effect steering. After making adjustments, always tighten all jam nuts securely before operating the boat. There are three jam nuts on the bar. Two of these are tightened down against the tie rod ends and the third jam nut is tightened against the center tube. There is no jam nut against the other end of the center tube because this allows for either engine to be tilted independently. 6. 7. I NOTICE I If the engines are not allowed to tilt independently of each other, the steering plates and related steering components June become bent when the engines are tilted.
Motors with toe-out (viewed from the stern) will ensure better boat stability. It is best if the exhaust wakes of two motors join 9-12 meters (30-40 ft) astern. 8. 1125 Date of Issue: June 2003 0 2001-2003 American Honda Motor Co., Inc.
