Help picking the right part for my DF50 of 1999

[eowhadi]

Hello,
I just bought a used DF50 that was originally purchased in 1998. So it must be a 1999 model, since I think DF50 only started in 1999.
the number on my motor is : 05001F 972566

I broke the shell, original manufacturer part number:
61810-87J00-0EP & 61821-87J00-0EP

now, when I go to Boats.net - New and Used Boats for Sale, Outboard Boat Motors, and Discount Outboard Boat Parts or to Houston, Texas, Bayliner, Key West, Triton, Trophy, Explorer, Cypress Cay, Boat, Outboard Motor, Dealer, Used, Parts, Service, Financing I get different answer and advice.

speaking with a representative of both company, I receive different answers:

for lmcboats, I need to buy:
61810-87J01-0EP & 61821-87J02-0EP

for boats.net, I need to buy:
61810-87810-0EP & 61821-87J01-0EP
but they are not selling 61821-87J01-0EP anymore

so now I don't know who to trust and what to do...
Any help would be greatly appreaciated, what is the difference between these parts...
Regards,
eric
