I find both sets of serial numbers on 500 generation plus and 500 bulldogs which I think are 540's. They have B&M huffers and 650 double pumpers topside.
Can you tell the difference between 500's and 540's just by looking.

I know these engines, I assembled them. The Starboard side had dropped a valve so it needed a .030 bore to clean up the cyls. We installed JE forged pistons at 8.9 comp. All new stainless Manley valves, everything magged and rods reconeditioned. The port engine had just been rebuilt, all I did was check all the clearances, reconditioned the rods and put new rings and bearings in it. They are 502`s, (starbord is now 509), what it says on the valve covers (apba or something) is who built them for Mercury racing. They are supposed to make 600 hp.
The port blower is a rebuilt one also. Please check the oil in them once in a while! (pipe plug on front, 20-50 oil is fine)
I hope I was some help, you have a good boat..... Ive driven it several times and to be honest the only reason you have it and not me is when it was time to sell I was too worried about the economy to bite the nut!
Have fun with it! Chuck.
