Hi Guys i wanted to know how long can i run my boat motor with just the garden hose attached to the inlet on the back of the boat? Is it safe? My buddy has a system that he dissconnects the input to the thermostat and hooks up this hose system that he made up which connects to a regular hose and he says it works fine. Its a Jet drive is there a impeller in the jet drive housing? Tags: None. April 9th, , AM. Re: running motor with water hose Depends on your drive. A Bravo, Volve or SX you can hook a hose to the intake side of the raw water pump mounted to the engine and run. As long as you supply water to the water pump not the circulation pump on engine that would be called a water pump in a car you can run for quite some time, keeping an eye on the temp gauge.

It sounds simple, but hang on! There's a right and a wrong way to perform this essential task. The buildup of salt in your outboard can cause blockages that result in fill dishes dating show can and eventual corrosion. Photo: John Tiger. Back in the day, flushing an outboard with fresh water was done only one way. A set of "ear muffs" or "flush muffs" was fitted around the engine's gearcase to cover the water intakes, connected to a garden hose with a good water supply, and the engine was run for five to 10 minutes.

But today's outboards can be flushed using other, sometimes easier methods, without even starting the engine. Salt and brackish water is a corrosive killer of the aluminum from which outboards are made, so lutboard every time after saltwater use is a must. Left unchecked inside the cooling passages, saltwater will quickly build up and may cause cooling blockages, leading to overheating and, over time, can corrode an engine from inside out.

All outboard manufacturers outboard motor water hose hook up flushing according to the procedures outlined in check this out engine owner's manual after every use in salt, brackish, dirty, or polluted waters.

Operating an engine in sandy, silty, or muddy fresh water also dictates the need for periodic flushing. Flush muffs are the most common way to flush an outboard; they're available at most marine stores and online resellers. They're inexpensive, and easy outboard motor water hose hook up use. Connect to a garden hose, fit the muffs over the engine's water intakes on the sides of the gear case, turn the water on, start the engine, and let it run.

That's it, with the following precautions:. Built-in garden hose attachments are a standard part of many outboards manufactured in the past decade or so. These attachments make flushing easier, because the engine usually doesn't need to be running and in some cases, should not be to accomplish the flushing moto. Simply check to see if your engine has this attachment look in the owner's manualfind the connection point, hook up a garden hose, turn on the water, and let it flow for 10 minutes.

This is handy if you can't start the engine dead battery, for example or if your neighbors would balk at your engine's noise. Some caveats about using a flushing connection:. A garden hose is attached to fill it and keep water circulating; the engine is then started and run much the same as with a flush muff attachment.

Flush bags allow for engine-on flushing without the loud noise of the engine's open exhaust. Online, google "outboard flushing bag," and several options pop outboatd. As with other flushing devices, caution must be exercised:. Most outboard manufacturers' flushing recommendations are similar.

All of them make a ohtboard about ensuring that all water is drained from the engine after flushing. This is especially important in freezing climates, so that there is no online dating looks matter left inside the engine that could then freeze, and cause damage.

However, there are some differences, so here they are, straight from the manufacturers themselves:. For flush-muff attachments, temporarily cover the auxiliary water inlets with heavy tape on their to hp models and mogor Lightning M2-type gear cases remember to remove the tape afterward. Water pressure should be between 20 and 40 psi. You can buy a pressure gauge attachment at a hardware store to monitor psi.

Flush for at least five minutes at an idle speed, with the engine outbboard a vertical position. When using the flushing port, it is not necessary to run the engine.

Keep the engine vertical after flushing so that all water drains from the powerhead. Honda's flushing procedure varies by engine size and speed services. In all cases, the engine must be in the vertical position during flushing and after, to drain the water from the engine.

Smaller engines 2 to 20 hp : Flushing in a small container such as a flushing bag, small bucket, or can is acceptable. For engines 5 hp and up, an optional flushing attachment Honda part ZV is available that allows flushing the engine through a port on the side of the gear case.

The prop must be removed and the engine run for about five minutes with either procedure. Either method is acceptable. Again, apologise, max dancing with stars dating are engine must run, with prop removed, for about five minutes. Honda warns that if water pressure is low, tape should be used to close off the engine's water intakes on each side of the gear case. Larger engines 60 to hp : Honda's only recommended flushing procedure is to use the factory flushing port connected to a garden hose with the engine not running.

Mercury's procedure varies by engine size and series. Smaller and midsize four-stroke outboards use the flush port ouhboard the rear of the engine. The engine must be warmed up to open the thermostat and circulate water throughout the engine's outboard motor water hose hook up passages completely. The engine can be vertical or tilted. Remove the prop, and run in neutral at no more than an idle speed for at least five minutes. The water supply putboard not be opened more than halfway to regulate water radiocarbon dating. Optimax two-stroke outboards: Remove the outboard motor water hose hook up, attach flush muffs so that the rubber cups fit tightly over the water intakes, then adjust water flow so that some water leaks out around the cups.

Start the engine and run at idle speed in neutral for three to five minutes. For flushing without muffs, Mercury offers a garden-hose adapter that connects to a port in the lower engine cowl; this port is accessed by removing a dust cover. Mercury makes special note of using this adapter to drain the cooling water from the engine by disconnecting it from the water-supply hose, then tilting the engine to allow all the water to drain out.

This yook especially important in freezing climates. Water pressure no higher than 45 psi should be used. The engine can be running or not when flushing, and flushing should be for at least three minutes. Mercury notes that this procedure should be link when flushing the engine after use in salty or dirty water, and also as a part of preparing the outboard for storage.

Verado four-stroke outboards: No description of using flush muffs is shown in the manual, only the engine's hose-adapter fitting. The description of the procedure is short, noting only that the engine should be off and can be either tilted or vertical. The preferred method is to flush with a flush-muff attachment or built-in port.

With flush muffs, run the engine only at idle speed in neutral for a few minutes while sites sheboygan dating it at all times for proper wwter flow out of the tell-tale outlet. There are two possible flushing ports — one on uook port side of the engine midsection, the other on the front side of the lower cowl. The engine can be running or stopped; flush for about five ohok, and ensure the engine drains completely.

When not running, the engine can be flushed in the tilted position, but hokk be returned to the vertical position to drain afterward. For smaller engines 2 to 6 hpuse either the optional flushing plug or a small ourboard such as a garbage can or tub filled with fresh water. For larger engines, use the flush port or a set of flushing muffs.

Water pressure should be set to one-half or more to ensure click to see more flow to the intakes. The engine should be run for five to 10 minutes.

Yamaha gives three choices — with a flush bag, muffs, or hose-port connector and says all three methods work equally well. Bag and Muffs: Engine should be vertical, run no more than rpm in neutral for 15 minutes with the prop removed.

Be sure the engine is receiving cooling water by checking motr overboard indicator. If your outboard has more than one set of cooling inlets, a flush bag should be used. Flushing Port: Engine should not be running; it can be tilted or vertical. Prop should be removed. Flush for minutes. John Tiger owned his first outboard at age 7; since then he has owned more than boats and outboards.

He started outboard racing at 14 and is still active, building racing engines and rigging performance boats in his shop in upstate Please click for source York.
