merc wires are made in mexico - bean counter made
Your ebay wires are the china ones good luck with those. Maybe a total of 3 USA dollars went into building those ebay wires, my guess is 2 bucks went into those build set of wires. And Im sure the emi and rfi is thru the roof.
For a small jist of info - Marine engines have wire harnesses all over the place thats why one of the reasons spark plug wires need to be of top quality including the boots. Also no air ever hits the engine compartments especially after shut down then heat soak takes place.

In short, yes. But I'd also second the msd or moroso 8.8 mil wire and making up your own terninations. Take the time to do it right once and you'll probably be in a retirement home sipping oatmeal through a straw by the time the wires need to get swapped out again.

The last two#'s stamped on the ignition wires from Mercruiser are the year the wires are made. Nice feature so we know how old they are. If 89 is last two #'s on the wires, yours are original as they where made in 1989. Yup, that old...lol...I removed a set of 88's on a boat last year....amazing...
Your engine should fall in this serial # range in link below. If so, click on 'Distributor and Ignition components' for the ignition wire part #.

So these should work? Says it doesn’t work with 454 hi performance, that’s not referring to the mag, is it??
Mercruiser wire sets are very good. I use them alot on boats I work on.. I gave you a way to look up the OEM part # and then go shop from there.
I've gotten some closer to $50.00 .
I would never suggest some unknown part shipped directly from Bejing. LOL.
