Hey Mercruiser gurus,
I just finished rebuilding a gen V mercruiser 454 Bravo motor. I bought an entirely new transom assembly. However, now that the motor is setting in the engine bay, the coupler on the engine is higher than the spline. I think all I need to do is shim up the front engine mounts, but before I do, I find it odd that this transom assembly is supposed to be a direct fit, and I did not adjust the motor mounts so it should not be this far off (the testing tool does not even begin to slide into the coupler, it is about half of the circumference too low). Going back to the records of when I bought this, the transom assembly is supposed to be a Magnum, but I was told the only differnce was reinforcement to make it stronger for more hp. I note that there are rubber pads on the rear enginge mount brackets on the transom plate, which would definitely raise the rear of the motor up, but I do not know if there are other differences that would make this install problematic. My questions are:
1) Is the magnum assembly really a direct replacement for the standard bravo assembly? Are there other differences between them?
2) Do I need to remove the rubber pads?
3) Do I need to remove the coil washer and/or the wafer washer to make this thing fit.
A thousand thank yous in advance, because this is keeping me from finishing this rebuild and getting my boat in the water, and my whole family is dying to get on the water because of the quarantining.
