running with a water hose/ear muffs
Just needing some verification on this one please. When I'm running out of water with the hose. I have the earmuffs hooked up and good water pressure. The water is coming out the exhaust ports on the alpha 1, but no weep hole to speak of that I can find, is this correct?:eek_animated:

Hi midwest mariah,
Not sure what you mean by the "weep hole" but if the outdrive is in the down position, the water should be coming out the prop and if the water temperature is OK, you're doing fine. WetWilly |
Re: running with a water hose/ear muffs
Not sure what it was called but weep hole was the best I could think of. it is the spray stream that is on outboards that verify's that there is water circulating through the engine.
I have a little water coming out of the prop, but the majority is coming out of the exhaust port, which is real close to the hull, one on either side of the outdrive. Temperature was running about 120 for 30 minutes idling. Its only a high of 77 today and 79 tomorrow, too chilly to get it out for the first time again:shakehead: |
Re: running with a water hose/ear muffs
Hi Midwest
On outboard motors there is a small jet of water that comes out to indicate that the engine is drawing water for cooling. Your outleg does not have one of these. What you have described indicates that everything is cool!:) |

GREAT NEWS, Awesome and very cool, thanks for your advice!!:eek_animated::yes_grin::rolling_laugh::wi nk_thumbup:;):p:rolleyes::D:punch_out:

Re: running with a water hose/ear muffs
How does water "come out of the prop" when you're on muffs? I would've thought it would go in the raw water intakes on the bottom of the drive, circulate through the engine and exit with the exhaust. ISTM any water appearing from the vicinity of the prop would just be water that leaked from about the imperfect seal the muffs have around the raw water intake.
Or do I completely misunderstand how these systems work? JIm |
Re: running with a water hose/ear muffs
Hi Jim,
The Mercruiser I/O's use a thru prop exhaust system. There is a rubber exhaust coupler from the transom to the outdrive and when you put the drive down the exhaust is routed through the leg and out the prop. Click here and take a look at the second picture of post #12 and you'll see the exhaust inlet for the outdrive and this leads down to the prop. Next time you have the muffs on, lower your outdrive down and put your hand on the back of the prop opening (Of course the shifter is in neutral, right?) and you'll feel the exhaust and water. You see, after the water is circulated through the motor it's routed into the exhaust manifolds to cool the manifolds, exhaust gases and the shutters down. It's a great design as it uses the back pressure area behind the prop to help scavenge the exhaust and uses the exhaust at the same time to fill in the pressure area all the while using the water as a muffler.

Thanks for the explanation, WW.

Re: running with a water hose/ear muffs
Does anyone have pictures of this hooked up..... I don't see where I can hook a water hose or earmuffs to my bravo III

You can kind of see where mine are in this video:

Where do I get them at

Before you go and buy muffs, you need to look at your waterpump. I also have the Bravo III and my water intake is a small port on the bottom of the hull and not on my outdrive. Apparently with the Bravo III, you can go either way. The way to tell is to locate your water pump on the engine(usually on the starboard side bottom front) and there are 2 hoses coming off the back. One should go to your engine(output) and the other will be your input and either go to your outdrive or go around your engine to a valve that is mounted on the engine room floor. If it goes to a valve on the engine room floor, don't put muffs on the outdrive because it won't work.(Believe me, I tried it when I first got my boat!) You will need to get a water flusher that looks like a toilet plunger. They are made for inboard engines, or install a t-valve with a garden hose fitting into your water intake line. Hope this helps! |

The plunger looking ones are often referred to as, fake-a-lake.
Thanks for the compliment, csterner. I often still smirk when I fire it up. |
Re: running with a water hose/ear muffs
If you are running a stern drive using a flusher, you should be able to place your hands on the top of the exhaust risers without any discomfort. As mentions previously a sterndrive does not incorporate a weep hole to indicate water flow. Be careful when using a motor flusher they will slide off of the outdrive due to the water pressure from the hose and slick painted surface. I use a duel intake motor flusher since I have a 7.4 and I use bungee cords to prevent the flusher from moving while I run the engine.
