Is an engine suppossed to be installed flat or higher on one side? The right side of my engine is about 3/4 inch higher than the left. This is causing some issue with exhaust hook-up. I have a 454/bravo one set-up.

It should be level. Might need some slight tweaks to get the alignment perfect.

Last year I paid a shop to align when dropping in my engine. They did the lowering-in and alignment and I did everything else with getting it to run. I guess I should give them a call.

Tilted sounds like the transom assemblie might be off,thats what controls the tilt of the engine.The mounts on the inner transom should be level from port to starboard. JOHNSR
