Pro-Billet Marine Distributor - BlackSmall/Big Block Chevy, Magnetic Trigger, Mechanical Advance
Brand: MSD
Part Number: MSD85603
Description:

Boat enthusiast will be glad to see the addition of the new MSD Black Marine distributor line.  Built off our tried and true billet marine distributors, the 6061-T6 aluminum housing is now hard anodized with a sleek black finish for great looks.

Under the black cap you'll find a quality rotor, pickup, reluctor and adjustable weight plate assembly (where applicable). Chevy applications use a .500" QPQ coated distributor shaft joined by a melonized distributor gear while Ford models run a .531" QPQ coated shaft and cast gear. Both ensure smooth operation, superior strength and long life even when challenged by harsh marine applications.

The Marine Pro-Billet Distributors have been tested by Underwriter's Laboratory and are certified to meet or exceed safety standards for marine ignition systems as set by the U.S. Coast Guard.

  • Designed for use in marine applications with Chevy V8 automotive engines
  • Black anodized for great looks and corrosion resistance
  • Will not accept a vacuum advance canister
  • Supplied with a bolt down HEI style distributor cap and rotor
  • Weathertight connectors are used for locked and sealed connections
  • Must be used with an MSD Ignition Control
  • O-ring seals can be added to modified blocks to improve oil pressure control
  • Special oil tract improves lubrication to the distributor and cam gear
  • Nylon pads ensure smooth operation of the advance weights

Tough Dog Balls. Bright Orange/holes for treats
Color: B) 3" 2-Pack (Bacon)
I used to buy Starmark. But their balls got smaller and tore more easily. The color was green. I couldn’t find it when it was dropped in the grass!! Soooooo, I took a chance on this cuz it had holes in it and was bright orange. It is not scented at all or its bacon scent faded. The ball is for strong chewers. I’m a petsitter and I needed tough balls for my clients dog. Shipped quickly. Good price. Exactly as described

Flavored Dog Rubber Balls
Color: H) 2.5" 3-Pack (Beef), Color: H) 2.5" 3-Pack (Beef)
My dog absolutely loves these balls, I have a few more I had already bought, but she has an addiction to them so I had to buy more. I am able to squeeze these really easily so when she does pick them up after I’ve thrown them they’re very easy for her to pick up. They have a good thickness to them so it’s not too flimsy. It’s pretty tough and they bounce pretty high which I like and so does she know she is an aggressive chewer, but I haven’t had an issue yet with her chewing right through these, which is why I like them and we both love the fact that it smells like beef I could practically smell them through the bag, but I have a really high pitched sense of smell, and I knew she was going to love them. Not to mention you can’t beat the price.

Love These Balls
Color: H) 2.5" 3-Pack (Beef), Color: H) 2.5" 3-Pack (Beef)
These are great balls. My Border Collie can destroy a tennis ball in a couple of hours and the Kong brand ball is heavier than I like to play with in the house. These balls hold up to her biting and chewing but are lite weight and softer for bouncing off the walls.

Seems durable - but the scent is not the best
Color: B) 3" 2-Pack (Bacon)
I don't know if I'd call the scent of this "bacon," more like rubber with a hint of bacon. It's very strong. I gave my dog one of the balls & put one in a cabinet where I keep his treats & a few other unrelated odds & ends. I now hold my breath when I open that cabinet b/c good lord, the smell. I'm tempted to just give that one to the dog too, just because it'll air out eventually & then everything else in that cabinet won't smell bad. My dog feels so-so about it. He'll briefly chase after it & chew on it, but loses interest in it pretty fast. My rather hyperactive cat also plays with it from time to time, as he seems to have more interest in most dog toys than the dog these days, so there's that. (Then again, he thinks a wide variety of random items around the house are loads of fun to toss about, so it's possible his opinion is to be taken with a grain of salt. Between the brief periods of one of these balls being chewed on & clawed at, it's stayed completely intact. I think if you have a dog who simply likes to play fetch or chew on rubber balls in general, this one would stand up to the task. But if you're expecting it to be greeted with the enthusiasm as a bacon grease covered ball might be - I'd adjust your expectations.
