Took lower end off Thursday, measured it, brought it in a turn, to 21 7/32”, must be the regular cross flow V4 because the 21 15/16” Joe suggested is unattainable. Couldn’t get enough cable adjustment at the engine to get it to shift right. So we took it apart again Friday, brought it out a turn to 21 9/32”. Now it measures the same as when I first took it apart. Shifts ok in both directions with some minor adjustment. Sea trial Saturday, ran ok for an hour, but on my way home something didn’t sound right. Was docking and I hit reverse and I stayed/crashed in reverse. Everything seemed locked up. Thought the worst, got home, drained gear lube, looked good, couldn’t get it into neutral though. So off comes the lower unit, AGAIN! What do I see? The shift rod’s unscrewed from the lower unit!!! So I screw it in all the way, 13 turns, measure it, back it out to the 21 7’32, 12 turns!!! Seems I’m only catching a half a thread at my old position and if I do bring it in a turn, and mess the the adjustments at the control end, that’s only 1 ½ threads. So I’m thinking go downstairs to the machine shop, cut it in half, and make a sleeve, and have it welded or brazed back together to make the thing ¼” longer. Could it be the wrong shift rod in there? Can make the necessary repair easy enough. But I am perplexed with this situation. <br /><br />Reference mat’l…..EL120TLCO<br />Luna Sea.... The measurement you received from whoever it was, pertains to the regular cross flow V/4 engines, not the Loop Charged engine that you have. The correct measurements are as follows:<br /><br />20" Shaft = 21-15/16" plus/minus 1/32"<br />25" Shaft = 26-15/16" plus/minus 1/32"<br /><br />The measurement is to be with the lower unit in neutral, and taken from the top surface of the gearcase housing to the center of the shift bolt hole.<br /><br />Drop the lower unit and correct the measurement. Failure to do so will result in damage to the shifter dog and at least one gear!
