Above the raw water pump is another pulley where the belt goes over? This is the idler pulley right?

It wont spin on my friends boat, its probably seized up and rusted? Is there a bearing or somethign behind it?

That large aluminum pulley should be your circulating water pump. If it doesn't turn you need a new pump. Judging by those rust stains on the muffler I'd say it's toast.

haha, that engine runs flawless... i was just show the pic.

Anyways a lil pb blaster on his pulley (not the one in the pic) and some hammering and it freed up. All is gravey!
