Take a few steps now to prevent a lot of time, money, and headaches later.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">An ill-maintained boat can quickly become a liability.&nbsp; (We encourage you to look over our <a href=\"https:\/\/www.neighbor.com\/storage-blog\/boat-maintenance-guide\/\">Ultimate Guide to Boat Maintenance<\/a>.)<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">One of the regular maintenance tasks of every boat owner is to regularly <strong>flush out your boat&rsquo;s cooling system<\/strong> to remove salt, debris, and other foreign gunk.<\/p>\n\n\n\n<figure class=\"wp-block-image\"><img  decoding=\"async\"  src=\"data:image\/png;base64,iVBORw0KGgoAAAANSUhEUgAAAAEAAAABAQMAAAAl21bKAAAAA1BMVEUAAP+KeNJXAAAAAXRSTlMAQObYZgAAAAlwSFlzAAAOxAAADsQBlSsOGwAAAApJREFUCNdjYAAAAAIAAeIhvDMAAAAASUVORK5CYII=\"  alt=\"\"  class=\" pk-lazyload\"  data-pk-sizes=\"auto\"  data-pk-src=\"https:\/\/lh7-us.googleusercontent.com\/kDvriLDxnEhs5gNgbY1yXqUtVYYG54rcL5Datrch2HYT0ouX7nzCohY38E8TgRBdv6z-7wMyAtdXCqVzE9TKThlst2mkN-qq2YxxlGaChhI0JOdouiHozpc4bHp4GA55DvWs0HURku9mXj-9Kuo6BZQ\" ><\/figure>\n\n\n\n<h2 id=\"why-do-i-need-to-flush-my-inboard-marine-engine\" class=\"wp-block-heading\">Why Do I Need to Flush My Inboard Marine Engine?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Most boat engines use water to cool the engine.&nbsp; Outboard marine engines typically have <strong>intake valves<\/strong> on the outside of the engine, while inboard marine engines may have intake valves built into the hull.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">While these intake valves do have a filter, particles, other debris, and other water-borne intruders can work their way into these intake valves.&nbsp; When this happens while out on the water, it&rsquo;s not a big deal. <strong><em>That is, unless<\/em><\/strong>, you consistently fail to flush out your cooling system when you get back to shore, allowing muck to build up over time.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The <strong>very worst-case scenario<\/strong> is to have your cooling system suddenly blocked.&nbsp; In this case,<strong> your engine can overheat and even melt down <\/strong>&ndash; just like a car with no water in the radiator.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Saltwater boaters take note: <strong>Salt is corrosive<\/strong>, so if you&rsquo;re using your boat on saltwater or estuarine water, you should &ndash; in the perfect world &ndash; <strong>flush the salt out after<em> every single use<\/em>.<\/strong> &nbsp; That may be an unrealistic goal, but the general sentiment is that if your boat regularly comes in contact with saltwater, you should flush your cooling system as regularly as possible.<\/p>\n\n\n\n<html><body><div id=\"in_post\">\n    <div class=\"control\">\r\n\t\t<a href=\"https:\/\/www.neighbor.com\/search?can_store_vehicle=true&amp;min_length=16&amp;min_width=10&amp;overrideTitle=Boat%20Storage&amp;storing=Boat&amp;types%5B%5D=Carport&amp;types%5B%5D=Driveway&amp;types%5B%5D=Garage&amp;types%5B%5D=Parking%20Lot&amp;types%5B%5D=Unpaved%20Lot&amp;types%5B%5D=Street%20Parking&amp;types%5B%5D=Warehouse&amp;types%5B%5D=Other\" onclick=\"rudderanalytics.track('press editorial cta button', {location: 'first in post', version: '2.2'}, () =&gt;

It will indicate how to find all of the intake valves.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">You&rsquo;ll also need a garden hose that can reach your boat, in addition to a freshwater source and appropriate valve adapters. The garden hose will connect your engine to the freshwater source, while <a href=\"https:\/\/www.boatspecialists.com\/ab-universal-valve-adapter\/\" target=\"_blank\"><strong>valve adapters<\/strong><\/a> will help you establish a secure connection between the hose and the engine&rsquo;s cooling system.<\/p>\n\n\n\n<h3 id=\"garden-hose\" class=\"wp-block-heading\">Garden Hose<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">A garden hose plays a vital role in connecting your inboard boat engine to a freshwater source. When choosing a garden hose for this purpose, a <a href=\"https:\/\/www.amazon.com\/HydroMaxx-Corrugated-Flexible-Tubing-MM-Metric\/dp\/B07N89TGFL?th=1\" target=\"_blank\"><strong>1-1\/4 inch diameter hose<\/strong><\/a> is typically recommended, as it provides adequate water flow for effective flushing.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Standard practice is to start with a low level of water flow, and slowly increase the amount.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In terms of how to connect the hose to your boat, you&rsquo;ll need to consult your owner&rsquo;s manual, as the input valves are different on each vessel.<\/p>\n\n\n\n<h3 id=\"flush-kits\" class=\"wp-block-heading\">Flush Kits<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\"><a href=\"https:\/\/www.westmarine.com\/engine-flushers-1\/\" target=\"_blank\">Flush kits<\/a> have two purposes.&nbsp; First, they provide valve attachments for different types of inboard and outboard motors.&nbsp; Second, some provide an additional solution for cleaning out your engine.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Some flush kits advertise additive solutions to remove salt. <strong><em>But do they actually help?<\/em><\/strong>&nbsp; You&rsquo;ll have to test them yourself.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Salt naturally dissolves into fresh water, so it&rsquo;s unclear if these are necessary.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">But what we do know is that crustaceans like to colonize boats &ndash; most obviously in the case of <em>barnacles and oysters<\/em>.&nbsp; But all sorts of microbiota <em>(plants and animals invisible to the eye)<\/em> can slip through the filter on the intake valve.&nbsp; For these critters, some flush kits offer a <a href=\"https:\/\/powerservice.com\/psp_product\/bio-kleen-diesel-fuel-biocide\/\" target=\"_blank\">biocide additive<\/a>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Usually, fresh water is sufficient to clean out your cooling system.&nbsp; <em>Note: the additional additives marketed with certain flush kits won&rsquo;t hurt your system, but we haven&rsquo;t tested them and can&rsquo;t say for certain how well they work.<\/em><\/p>\n\n\n\n<h2 id=\"step-by-step-guide-to-flushing-an-inboard-boat-engine\" class=\"wp-block-heading\">Step-by-Step Guide to Flushing an Inboard Boat Engine<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Now that you have the necessary tools and supplies, it&rsquo;s time to begin the flushing process. This step-by-step guide will walk you through the process of:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li>Locating cooling system components<\/li>\n\n\n\n<li>Connecting the hose<\/li>\n\n\n\n<li>Running water through the system<\/li>\n\n\n\n<li>Checking for proper flow<\/li>\n<\/ol>\n\n\n\n<p class=\"wp-block-paragraph\">Following these steps facilitates effective flushing of your inboard boat engine, contributing to its optimal performance and longevity.<\/p>\n\n\n\n<h3 id=\"1-locate-the-cooling-system-components\" class=\"wp-block-heading\">1. Locate the Cooling System Components<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The first step in flushing your inboard boat engine is to locate the cooling system components, such as the raw water intake and flushing valve. You can find these components by consulting your owner&rsquo;s manual.<\/p>\n\n\n\n<h3 id=\"2-connect-the-hose\" class=\"wp-block-heading\">2. Connect the Hose<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Every boat has unique intake valves.&nbsp; The owner&rsquo;s manual will tell you how to locate them and connect them to your hose.&nbsp; You may need additional attachments from a flush kit to marry the hose to the intake valve.&nbsp;<\/p>\n\n\n\n<h3 id=\"3-run-water-through-the-system\" class=\"wp-block-heading\">3. Run Water Through the System<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Now that the hose is connected, you can begin running fresh water through the engine&rsquo;s cooling system. Turn on the water supply, and allow the water to flow through the hose and into the engine for several minutes.<\/p>\n\n\n\n<h3 id=\"4-check-for-proper-water-outflow\" class=\"wp-block-heading\">4. Check for Proper Water Outflow<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">You can assess the water flow by observing the water exiting the exhaust port, which is connected to the exhaust manifold.&nbsp; If the flow is steady and clear, you can be confident that the flushing process was successful.<\/p>\n\n\n\n<figure class=\"wp-block-image\"><img  decoding=\"async\"  src=\"data:image\/png;base64,iVBORw0KGgoAAAANSUhEUgAAAAEAAAABAQMAAAAl21bKAAAAA1BMVEUAAP+KeNJXAAAAAXRSTlMAQObYZgAAAAlwSFlzAAAOxAAADsQBlSsOGwAAAApJREFUCNdjYAAAAAIAAeIhvDMAAAAASUVORK5CYII=\"  alt=\"\"  class=\" pk-lazyload\"  data-pk-sizes=\"auto\"  data-pk-src=\"https:\/\/lh7-us.googleusercontent.com\/patJxuM-8P9wxxCouwzX_TdHMKpqRvu0-NhF7N_w6EzNZQyLvsj863jhpv0Nv0DbfrMO6cUdA5KAZGF1a5qOtMfZTOQA8KJHFUvqZCkzcJhUZ6VIzZ1PzMDVvmdHV7u1xLkuoWbFDxgQUI11aUKHxgk\" ><\/figure>\n\n\n\n<h2 id=\"tips-for-effective-inboard-engine-flushing\" class=\"wp-block-heading\">Tips for Effective Inboard Engine Flushing<\/h2>\n\n\n\n<h3 id=\"how-long-should-i-flush-for\" class=\"wp-block-heading\">How Long Should I Flush for?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">As a general rule of thumb, it is advisable to flush your engine for 10 minutes after each use.<\/p>\n\n\n\n<h3 id=\"can-i-flush-a-hot-engine\" class=\"wp-block-heading\">Can I Flush a Hot Engine?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">No.&nbsp; Flushing a hot engine is a bad idea.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">It&rsquo;s important to flush your engine when it is cool to avoid damage from <strong>thermal shock<\/strong>.
