1995 454mags factory sealed?
 

Looking at a boat with 454 mags from 95, owner tells me they were rebuilt a few years ago when he bought it, but no paperwork, spoke to dealer where they sold boat and have no record of it either, so i'm wkndering if these motors had the.seal on the back like the 500/525s. im pretty sure my 502 in the 271 had one also.

I am not sure about 1995 but my 1991 454 Mag, which I bought new, did NOT have the seal. Hope that helps.

No seal!

My 502's don't have seals. Thought that was just for the HP motors
