When I bought it, the spark plugs were NGK radio suppression plugs BPZ8H-N-10 at $10 each. The standard plug is BP8H-N-10 at $3 each. Can I use the standard? Thanks Back to top Pegsguy Posted: Sunday, November 01, 2009 10:35 AM Joined: 11/22/2008 Posts: 1388 It won't affect the way the boat runs, but may raise hell with your electronics and those of anyone near you while your motor is running. Could make you very unpopular on the water. With a motor that new, you should only need to repalce the plugs every 3-4 yrs. How much will you save on an annual basis? Tom Fishin' fool in N.E.

I will take your advice and stay with this plug.

Where did you get your prices? Check a local auto parts store, most have access to a full line of marine parts at much lower prices than a marine dealer. $10 ea. sounds high for that NGK part number, I usually pay about $10 for a platinum plug, and by the P/N that is not a platinum plug.

Buy the higher end plugs and keep 'em as spares until needed.

An NGK plug purchased at Wal-Mart is the same as the same P/N from a marina or boat dealer. It pays to shop as boat owners are targets. Tom Fishin' fool in N.E.

Over the winter I’ll check the auto parts stores, Thanks Back to top
