I have a 27 foot tiara with twin crusader 350 matched with borg Warner 1.52:1 trannys. out of the water I replaced the shafts, couplers, Cutlass bearing's, stuffing boxes, and recondition the props. Also had to change the rear motor mounts because the plastic adjustments were frozen tight. I aligned everything up while on blocks to within .001 of an inch on my star board motor and .002 of an inch on my port motor. I went in the water went for a test run and I'm getting vibration.
OK so I check the alignment again in the water and it was off. I adjusted the engine mounts on both motors and was within .002 on each engine. Trial run still have vibration. So I go to check the alignment again. And it's off-again I fine tune it and get within .0015. I turned the Coupler on the shaft 180? and I get different gaps. I then slid the shaft as far back to the shaft log as possible started the motor and put it into gear and can visibly see a wobble on the transmission flange. Now what?
What could be wrong besides a bent or warped flange? Is it as simple as taking the locknut off the center of the flange and replacing the flange itself or could I have internal transmission problems?
