How to add a Shutoff Valve to your boat's cooling system

[tdonoughue]

My valves are similar, @Monster77 .

Squirt some WD40 or CRC on those valves. Mine are rusting something awful (after several years, mind you).

Thanks, good to know

I don't think the Sea Tow driver knew this equipment as there is NO difference between the 2 and 4 stroke engines with regard to water ingestion on a dead engine above no wake speed. Another nice feature of the tow (isolation) valves is the ability to flush your engines with fresh water while sitting in the salt.

How does that flushing tip work? I just bought a Yamaha 190 FSH which I researched well but never realized until after the purchase that it would not be able to be docked in saltwater. For some reason, it never occurred to me that there would be no way to flush it out so now I am at the whim of the marina to put the boat in and out, and that was not my intention as I like to fish when I want to fish whether it’s four in the morning or four in the afternoon. So I am really interested in what you say about being able to flush salt water out while it’s in the water.

@Tylenator run through this thread. You'll see why I'd still suggest this for the issue you were having. My well is an artesian, and puts out less pressure than yours, most likely, so I'm familiar with the problem you were having. This will help, even with the wife taking a shower, as well as help you if you ever need to be towed, or run through some Salt Away. The easiest version is the hose clamps I mentioned, this is a more permanent solution. Another reason to at least look at it when you get your boat back, is to familiarize yourself with where and how to clamp the hose off, in case you need a tow. Better to know, before you go!

When you have the tow valve(s) installed you can turn the valve off, then use the flushing port and supply water to the engine, start engine-turn on water-turn off water-turn off engine, and you will flush the salt water out of the engine.

@lazergeek has THE best set up for this.

Noice! Have you posted about that mod? That might actually make installing tow valves worth to me.

Search "live well access" and you will find my thread where I did that

I take it you want to fill the live well with fresh water before heading out onto salt water? Pretty crafty way to get 26 gallons of fresh water without taking up storage space adding a separate tank!

Yep, I have just been using the straw method with my intake hose to my washdown pump for now, it works great. I put a y valve in the intake so I can switch bewteeen the factory raw water intake or the fresh water to the washdown pump.
