Re: Does a outboard motor have an alternator?
rogerwa, might I ask you a question related to the alternator in a 85 Force? Or should I make a new post? Thanks [links]
Re: Does a outboard motor have an alternator? [links]
Unless you are running say an 11-17′ boat. Two batteries are the way to go!
It’s something to think about if you only have 1 battery in the boat, or if you have 2 batteries, how to use the battery switch. We’ll touch on that in a little bit.
Smaller engines don’t need a lot of Marine or Cold Cranking Amps, (MCA & CCA). A 20 HP only needs to have like 350 MCA’s, or a 150 HP only needs 675 MCA. Whereas a 350 Verado recommends having an 800-1000 MCA and a Group 31 Absorbed Glass Mat battery!
With so many different variables that can play into the answer, we’ll try and keep it simple! more
Then, once you get where you are going, simply change the switch to either of the battery positions. [links]
So it is regulated to a certain voltage, usually around 13-15 VDC (Volts Direct Current). With the extra power being sent to the ground.
Corrosion often occurs where wires meet. Visually check electrical blocks under the dash and/or in the bilge. Also, check any connections on gauges or add-on electrical equipment like battery switches, plotters, or fish-finders. Wiggle wires and connections to check for looseness. If either is found, disconnect and clean the connection with emery cloth or fine-grit sand paper, then re-install and tighten properly. Finally, spray all electrical connections with a product like Yamashield ™ , which puts down an anti-corrosive layer and leaves behind a protective film that helps prevent corrosion going forward. [links]
All battery cable connections must be clean, tight and use hex nuts and lock washers (not old- fashioned wing nuts). Loose connections can cause frustrating intermittent issues or a full-time “no run” condition. A dirty or corroded connection can impede electricity’s ability to travel, and a battery terminal connection may be corroded, yet appear clean. To avoid any doubt, always remove the terminal connection and clean both sides of the connecting materials down to bare, shiny metal, then re-install and tighten the connection properly. For regular maintenance, use Yamalube ® Battery Terminal Cleaner & Protector. Simply spray it on and watch for the foam to change color, indicating that the corrosion (acid) has been neutralized. It then dries into a thin, waxy film, preventing the build-up of additional corrosion. here
Caution: Make sure that there are no fuel fumes present when making, breaking, or checking battery connections and condition. Give the area the “sniff test” to check for fumes. If in an enclosed area, run the blower or thoroughly air out the space, or take the battery outside to test it. Please plan and protect accordingly. here
If you haven’t already sprayed connections with Yamashield or Yamalube ® Silicone Protectant & Lubricant, remove the outboard cowling and liberally spray the entire powerhead. Not only will it help prevent corrosion, but it will help keep rubber parts (like your cowling seal) supple and able to do their job effectively. [links]
Make sure to use the right size and type recommended in your owner’s or service manual (see chart on next page for general specifications). If there’s any question about a battery’s performance, have it load tested. Any auto parts store can do this for you, or you can do it yourself with the right equipment. here
Then, leaving the black lead on the negative post, put the red to the positive post and see what the battery voltage is. Make sure you remember this number!
You got the boat packed with your gear and your best friends. When you go to start the engine, it simply clicks. Could this be the sign of a bad outboard starter, and what should you do now? As to. more

If you have a trolling motor, then the battery charger is a must! If you don’t have a trolling motor and are only running 1 or 2 things on the boat, then you can probably get away with not having a battery charger. [links]
