My brothers motorized dock has an 1989 classic 50 on it. He dosen't have a manual and I need to know what are the best spark plugs for this engine?

Thanks for the reply. Do you happen to know the part # ? He keeps it at the lake and and it's a 1.5 hr drive to get there. I had her running good till he let one of his scuba instructors borrow it. He says it is smoking and won't idle so I figure someone got the oil mix a little heavy.
