What hp and year?

[kbh121956]

Hello, I have a Mercruiser straight 6. It was winterized and removed from a friends boat when the hull was damaged. I've had it in my garage for years, I turn it over several times a year. On a machined flat surface is a stamped number F0508TAB. It also has raised lettering of CON 2 E 6 0. In the middle of the block are these numbers, 473483. The oil filter is a spin on style just in front of the fuel pump. Anyway I kind find what year and horse power this is? Thanks.
