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.

Features:

  • 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
  • Advance weight pins are staked and tig welded to the plate
  • Mechanical advance assembly can be locked out for crank trigger systems
  • Advance plate and weights are fine blanked from chrome moly steel and QPQ coated for friction reduction
  • Polished steel shaft is QPQ coated and guided by a sealed ball bearing and extra long sintered bushing
  • Maintenance-free magnetic pickup and precision reluctor create stable trigger signals throughout the rpm range
  • Easy-to-adjust mechanical advance with supplied springs and stop bushings

Not a reliable charger
Color: BLACK
The car holder portion of this item is incredible. It automatically closes around your phone when it detects it and keeps it very snug. You press a button on the side to release and that's it. Now the charging part of this is pretty bad. i understand that wireless chargers are not as fast as wired but when i use this it would take over 3 times as long as a wired charger. If a plug says 45 min to charge this would take at least 2 and a half hours. It is great for roadtrips or if you drive constantly but for any short trips the charging is negligable. I also have used it without a case to see if that was the issue and it was not. At the very least it keeps your phone at the same charge on short trips so I guess that's good.

Great product, great for the delivery drivers out there
Color: BLUE
If you are debating about getting this dash mount, get it. I haven't fully tested the wireless charging but I have a pretty uneven surface and it sticks extremely well, the holders that hold the phone are electronic and they sense whether or not the phone is in there once open so it won't just close randomly. If you turn the car off, you can release it, go away for a few minutes and then come back, set the phone on there, and turn the car back on, and after a few seconds it will clamp. If you press the button while the car is off it will clamp as well. I would recommend testing whether or not it wireless charges on whatever one you get, just in case of a defect, and you don't even need to take the film off to test it. This one is one hundred percent worth the money..

Rock-Solid MagSafe Mount—Perfect Fit for Tesla Interiors!
This Tesla MagSafe phone mount is hands-down the best car mount I’ve used. The magnetic strength is incredible—my phone snaps on instantly and stays firmly in place, even over bumps and sharp turns. It truly lives up to the “strongest magnet power” claim. The design looks sleek and factory-made, blending perfectly with my Tesla Model 3/Y/S/X interior without blocking the screen or vents. Installation was quick and tool-free, and the mount feels extremely secure once attached. I love that it works flawlessly with MagSafe and also holds non-MagSafe phones just as well. The viewing angle is ideal for navigation and hands-free use, making driving safer and more convenient. If you’re looking for a premium, reliable, and stylish phone mount specifically designed for Tesla, this one is a must-have accessory. Highly recommended!

Super Strong Hold with Magsafe & Sleek Design
I recently picked up this Tesla phone mount, and so far, I’m really impressed. The build quality feels solid, with durable plastic and a secure grip that holds my phone in place even on bumpy roads. Installation was straightforward—no tools needed—and it fits neatly behind the screen without blocking any view or controls. The magnetic ring provides extra stability, and the adjustable arms are wide enough to fit most phones, even with a case. It rotates smoothly for both horizontal and vertical viewing, which is perfect for navigation or hands-free calls. Overall, it’s a sleek, practical addition to the Tesla interior. If you’re looking for a minimalist, stable phone holder that blends well with the car’s design, this one’s definitely worth it.
