Can any ony tell me what the differance is between the differant generations of the Mercruiser 4.3L. I am doing reserch on the engine and see it is split into several groups by year. I am most intrested in the differances between 1980-1989, 1990-1995 and 1996-1999.
Now the reason, my brother is considering getting a running fully dressed mercruiser 4.3L that was rebuilt last year with a truck block for a really great price. We would like to re-build the engine useing a proper remanufactured marine block from usengines.com but the seller dosnt know the origional manufacturing year of the engine. So we are trying to figure it out via the rest of the engine.
It has the plastic cover on the flame arestor and reads 4.3 liter in large letters and underneath says thunderbolt ignition/power steering. But dont want to put my trust in a cover that can be added or removed willy nilly.
I just dont want to get in a spot were we have the motor and when we order the new long block things dont bolt on as they should.
Thanks
