so what I am visioning, when they set the motor back in, the inner transom plate is there and not adjustable left to right so once they pop those bolts for the rear motor mount to the inner transom plate, the front mount are going to go where the front mounts go- even if that means new holes...
Ayuh,...... When yer hangin' a new motor that was never there before,.....
Ya hang the motor on a hoist, set it down on the rear motor mounts, with all the hardware, drop the bolts in, 'n Just snug 'em,.....
The nuts for those bolts, I tape into their captive slots, before movin' the motor in,.... 'bout any tape will do,....
Then ya slip the alignment bar into it, 'n align the motor, while hangin' on the hoist,.....
Properly hung, a few shakes, 'n wiggles will show ya the center for the rear mounts,....
Provided the rear mounts are in good shape of course,...
Measure up to the pre-assembled front motor mounts, pre-adjusted to 'bout centered, to see where the wooden mounts, if applicable, need to be built up too,....
As deep as yer diggin', I'd expect it to come in close, but I wouldn't count on it bein' aligned,....
