Car Parts You Can Use in Your Boat, Motorcycle, or ATV

Has this ever happened to you? You’ve rented a cabin in some remote location and brought your ATV/boat/dirt bike for a week of fun in the sun. You unpack the car, stow the groceries, and head out for a ride. But your toy won’t start. The closest specialty shop is an hour away, or the marina is going to charge you an arm and a leg to fix it. Before you let mechanical problems ruin your vacation, stop by your local auto parts store. Many parts for sports machines, like batteries, are interchangeable with automotive versions or can be found at a general automotive store. Here’s a short list of parts that fit that description.

Batteries

Most auto parts stores carry a wide range of batteries that fit boats, ATVs, dirt bikes, jet skis, snowmobiles and even golf carts. Make sure you bring in the old marine battery or whatever type it is and get it tested first to confirm that’s the problem, to get the right replacement size, and to avoid the core charge.

Spark plugs and wires

Spark plugs and wires are another category that you don’t have to rely on a specialty parts supplier for. Even if you think that glow plugs for a Kubota B20 diesel tractor or plugs for a Yamaha Tt-R225 dirt bike are uncommon and only available through a dealer, think again and try your local auto parts supplier first.

Boat engine parts

Similarities exist between inboard motors and some car engines. For example, the 4.3 liter GM V-6 that’s in your 2000 Glastron boat may be able to use some of the same 4.3 V6 GM motor parts that are available at an auto parts store. Always consult your owner’s manual first though. Follow the manufacturer’s recommendations to ensure your warranty isn’t voided.

A little preventive maintenance before you hit the trail or water can help you avoid many of these problems in the first place. But if they do crop up, you now know that many of these parts are readily available somewhere other than just a specialty powersports provider.

 

Of course, anyone attempting repairs or maintenance should always consult their owner’s manual before undertaking any work, to ensure safety and that warranties aren’t voided.

    Be careful when you need to replace electrical items – alternators, etc. Marine grade parts are more expensive, but they are designed to survive a harsh marine envoirnment and resist creating sparks that can result in an explosion when gas vapors are present. The United States Power Squadrons (100 years old in 2014) specifically advises caution in their training manuals when considering substituting automotive grade parts for marine grade parts. USCGAUX also issues similar cautions. Bilge blower motors, distributors, alternators/generators need to be resistant to sparking to be safely used in confined spaces where gasoline vapor may accumulate.

    • Thanks for the comment Bill – Safety first, for sure!

    • Bull crap Bill , I’ve been a mechanic for over 20 years and I’m ASE master certified I started in the automotive industry then , went to heavy equitment then to marine and I can tell you that they tell you the marine is different maybe it was back in the 60’s but since the 90’s it is all the same on inboards and they tell you not to get electrical parts that aren’t marine and I can tell you I have rebuilt a many starters and alternators and there isn’t not one dam difference ! Motors use to have brass freeze plugs but now all engines run brass freeze plugs I worked at a Chevy dealership for over 10 years and have been in a many motors ! Also on the spark plugs the only difference in the marine plugs is there stainless steel and want rust but automotive plug will do the same thing ! People just want you to pay that extra couple thousand for a motor that has a mercruiser stamp on it or Volvo stamp but it is a Chevy motor ! No special cam or crank same truck motor !

  2. Totally agree and at about one-half the cost of marine, or tractor brand parts.. Like about 10 years ago I installed a honda automobile alternator onto an old Kubota tractor, imported from the rice patties afar, and it is still working great. (Alternator was purchased used from a automotive salvage yard)

  3. Some automotive parts may be interchangeable with marine engines, but it’s not always recommended.
    Marine parts are usually explosion proof or at least resistant due to the engine being in a closed area that’s not well vented unless you run the blower. I had a IAC fail on my mercruiser and replaced it with one from a local automotive store. It is a completely sealed device, so I feel confident I won’t have any spark issues from it.
    My suggestion is to check the automotive products before you purchase them and make sure they won’t cause an unwanted accident. The money you might save by using a non-marine part is definitely not worth yours or someone else’s life.

  4. This is about the worst advice I have ever seen in print and I will explain why. Gas vapors are heavier than air. Gas fumes therefore settle in the lowest compartment of your boat, namely, the engine compartment and bilge. Marine grade parts are specially designed to prevent SPARKING. That’s because, one spark in your engine compartment can cause your boat to explode. Don’t believe me? Google boat fire, marina fire, etc. It happens every year during boating season. Some jackass puts a car starter in their boat, turns the key and blows up often causing the whol marina to burn down. DO yourself a favor and pull this article down before you get yourself sued.

  5. I’ve had my share of Mercruiser Big Block powered boats with Bravo drives. Keep ’em. Car motors belong in cars… LOL… Yamaha Powered Boats Rule! And yeah they are expensine too. Boat stands for Break Out Another Thousand!!!

  6. Better think twice before instaling “automotive” parts in that marine application. We now live in an era of Lawyers go out of their way to find a neglegent party and penalize them to the fullest extemt of their pocketbook and Insurance companies that will find a way to rejecting a claim. Both of these entities have an enormous amount of resources at their disposal. Just watch the TV and you see ads all day for a law firm who will “fight for your rights”, we want to get you compensation all all costs, i.e. we want to capitalize on your misfortune…

    Thanks for your comments. We’d like to take this opportunity to weigh in on the conversation.

    We wanted to talk about options available for parts when in a pinch, much like our Mechanic Next Door describes at the start. His point around boat parts is that there are some similarities and different parts possibilities available, and that you do not necessarily have to go to a specialty shop for everything.

  8. I had dropped a 350 small block in my boat but i didn’t do my math and heated up the engine to extreme temps. What i needed to do was change the transmission to make a better ratio. http://autoeffects.org was a big help in this department. The right tools and the right knowledge could of saved me a lot of trouble.
