Question and Answers

Q:

What do I need to do 21759462 Craftsman Sears 4.5 hp outboard motor

A:

Thank You for choosing Sears PartsDirect.com. Glad to help out. Im looking at your model number 21759462 and it is Aug 1987 and the information I found online shows "24-1, although with the newer 2-stroke synthetics you could run 32-1. start with the 24-1 ratio and do a plug check after running at top end for a period of time the plugs should have a chocolate brown color. i recommend having a spare plug just in case it fouls out. i know that the later models can be run at 40-1, even at 50-1 in the newer models mid to late 80's." I hope this information helps you.  If you have further questions please resubmit your question for further information.
