Gen V has a steel old school looking timing cover ( has kinda like the blue cross looking syllable stamped on the front of it) and the Gen VI has a smooth faced aluminum timing cover..

If you want to spend $7 and have something that can read Kindle books, you can get Mike Mavrigan's "Rebuilding the Gen V and Gen VI BBC" which has about 2 chapters on this topic. Although not that common, there were Gen IV 502's, and relatively plenty Gen V 502s.

True, unless its not the original engine. I had a friend that had a 93 model boat and it had a Mark IV engine from the factory(not a baja), I think they must have had a bunch of leftover engines. A mark IV has a fuel pump boss on the engine, gen V and VI do not.

The Gen VI timing cover is cast aluminum with 6 bolts. The Gen IV and Gen V has 10 bolts. If that engine is original from 92, its either a Gen IV or a Gen V. there are casting numbers behind the timing cover that should tell you, and casting numbers on the flywheel side of the engine that might tell you. Gen V and VI also have 1 piece rear oil seals- which does not help you unless you remove the engine.
