Tips for Keeping Our Water Blue

Tips for Keeping Our Water Blue


At AAA Marine Wholesale we believe in boating responsibly and keeping the environment safe for anyone who comes to enjoy it. We adhere to the Boy Scout’s principal of, “Leave it better than you found it” and when it comes to the water there are many things we can all do together to keep the water clean, animals healthy and ensure future generations will be able to savor the open water’s beauty the same way we have. Here is a list of some handy tips to responsible boating:

  1. Regular Engine Maintenance

    1. Keeping your engine in tune will not only reduce your emissions but it could save you money too! Regularly check fuel and oil filter for leaks and replace when necessary. Engine parts designed with performance and efficiency in mind can increase the economy of your vessel while also reducing waste. 

  2. Manage Trash and Waste Water

    1. Never throw away trash on the water. Many animals will often confuse human trash for food and this can lead to the death of animals. Plan ahead when it comes to waste water. Some shore facilities will have pumping stations for waste water. Never dump waste water near shore or in an area without open water i.e. marina, harbor or bay. Hazardous materials like batteries, oil and oil products and antifreeze have designated collection facilities. 

  3. Watch your Greywater

    1. These days there are many green alternatives to soaps that should be used when doing dishes or taking showers that can minimize one’s impact on the environment.

  4. Use Green Bottom Paints

    1. Antifouling paints often contain many heavy metals which can be damaging on a marine ecosystem. There are alternatives which are considered safer but be sure to check the label before purchasing. Also using non-abrasive hull cleaning practices can keep the paint on your boat and out of the ecosystem.

  5. Stay Dry

    1. Whenever possible, save maintenance for the boatyard where they often have methods in place to minimize their impact. Dry storage is also a viable alternative for some which could save you money in the long run. 


AAA Marine Wholesale is committed to making the water safe and clean for the future. We hope you join us in this endeavor. We have many products which can increase the sustainability for your boat’s engine, check them out here

440 Chrysler Marine Distributor Problems

(this would also apply to 383, 426 wedge and RB440 marine engines)


Chrysler Marine called them “thrust collars”. These "spacers" fit between the iengine block and the distributor and raise the distributor up ¾”. There are 3 different lengths depending on which marine engine you have. They were necessary on the starboard engine of twin-screw boats and in any engine that had the rotation reversed from automotive. The reason is that when you reverse rotation, the distributor thrust is upward rather than downward like GM and Ford and distributors aren't designed to handle upward pressure.


The port, or standard rotation engines like automotive, don’t need this thrust collar and can use a distributor length of 4”, on 440s. Distributor length is measured from the mounting flange on the distributor to the bottom tip. The reason CM used it was to keep marine distributor lengths all the same at 4 ¾”. Thrust collars are necessary on reversed engines but not necessary on standard rotation engines.


AAA MARINE PARTS WHOLESALE (aaamarine.com) usually has both, and you can mix them or use the thrust collar on both engines and 4 ¾” distributors-it’s your choice. info@aaamarine.com
