Trying to figure out what engine i have exactly

Im very new to boating so excuse my ignorance on the matter. I have a pontoon boat with the following engine description:

5.7 Litre Turn Key Start Mercury Mercruiser
Serial: 1A081975
D.O.M.: 2007

I know its a 5.7 litre, but im trying to figure out if this is a GM motor or a Ford so I can for example buy oil filter for it.
It has an alpha one gen 2 stern drive if that makes a difference.

If I look at the following url: http://www.iboats.com/Mercruiser-Oil-Filters/dm/view_id.269912
I have no idea which oil filter it is. Is the number next to them the original number for a mercury oil filter? or the boat engine information? Also, Im assuming my oil filter isnt using a remote filter. Its located facing the engine from in side the pontoon on the front left side on the lower end of the engine block.

Thanks for any assistants

its a GM motor. you may want to buy the shorter can to allow you to get it on/off in most boat installations. also, you posted in the outboard section, this is an I/O motor

Re: Trying to figure out what engine i have exactly

See shows you how much i knew that. Will all those oil filters work? Maybe execpt the remote one?

I created the same question on the rite section I hope:
