If you are using the newer style rear mounts , you should be using fiber washer only, no split/ lock washer( double or single) between bell housing and inner t/a. Once rear bolts are installed and tightened (with alignment tool out) , support engine and transfer chain to lifting ring at thermostat housing area (engine centerline) only ( no chain support anywhere else on engine). This lets engine center itself. Lift/lower engine until alignment tool enters coupler ( never use hammer , no matter how tempting) . When alignment feels decent, mark mounts and drill.

Bolt the flywheel housing to the inner plate, install the the alignment tool with the front of the engine hanging. Then set up your front mounts. If you can’t get the tool in the coupler with just the rear mounts in, the inner plate is not square to the outer, the flywheel housing is cocked or the coupler is twisted. Time to start over at step 1

I tried every possible combination at the rear mounts. Lock washer, flat washer, no washer. A single lock gave me the best results. I had help, and after pinning the rear mounts only snug, we gradually raised the front. Dead center of the block and hull level. Bottomed out was the sweet spot. Only until gradually moving the block left (port) did the the bar begin to show little resistance and uniform grease marks. I tried to adjust the bearing to get closer to center, but the bar became tighter with each attempt. Everything is good with the coupler, flywheel housing, TP, and TA! It was put back in exactly the same location it came from. What is the 3-4-5?
I take no offence or have an arrogant attitude toward any advice. I exercise patience when I work, and strive to be the best mechanic and craftsman I can be. You haven't offended me in any way!

3-4-5 is a method of checking for square. Essentially you measure out a triangle 3’ on one side, 4’ on the second side and if those two sides intersect at 90* the third side will be 5’. It sounds like you have found alignment to me. I would button it up and go boating.

I feel compelled to get to the bottom of what's causing this problem. Is it my hull or did I screw up somewhere? With all of the hours I have into this project, it's kind of frustrating to run into something like this. After this weekend I should know for sure. Thank's to everyone for your input!

Is there an OSO member near your area who could potentially look at what's going on. I think it comes down to recent transom repair.

Yes, a fresh pair of eyes might spot it in no time.

I do have a friend who owns a machine shop. (A good friend to have!) He may not be familiar with boats, but I can get his opinion. When the first sheet of ply went against the transom, it was quickly clamped in every available place with bolts and pieces of wood for backup plates. Exhaust cutouts, cleat locations, swim platform holes and the opening for the drive assmbly. I think you get the idea. I preformed some surgery to find out if something may have gone wrong at the transom. I used a 7/8" hole saw to extract 2 plugs just above the TP. Nothing wrong with the plywood and a good laminate of the 2 layers. Peeking into the holes I could see the outer layer of the plywood that ripped off the plugs was still attached to the resin. I thickened the resin used as the adhesive with glass beads. I would have preferred to use foam if it wasn't so damn expensive. I come to the conclusion it has nothing to do with the transom repair. At least as far as I can tell!?

A squared + B squared = C squared! Basic geometry. I used it to square up my shed foundation. Duh!

Please let us know the final answer. Very curious
