Blowout Plugs

I came across this item and was wondering if anyone uses it:

Last summer I was having an issue with weak water flow from the "pee-hole". I changed the water pump (impeller) but it turned out that the impeller was not the problem. My water lines were just about packed solid with sand, silt, and other crap. Would using this at the end of the season help or do more harm than good?

Thanks,

Tony

should work great! I may buy one for my camper!

Yep, that's what you screw into the water inlet of an RV to blow out the water when winterizing the RV. I have one. Putting too much air pressure through the water system could cause some damage, however.

I find it easier to just put 2 gallons of RV antifreeze in my tank, cut on the 12 volt pump and run the water through each faucet until it turns pink.

I use one on my water system at the lake, I camp year round works great for that just watch the pressure. How would you plum it in on an outboard?

Many of newer outboards have a hose flush port. The hose adapter is primary intended to be used to flush out engines utilized on salt water with a fresh water hose to remove corrosive salts. Now as far as the OP intent of utilizing air to flush out debris accumulated in an engines cooling I have no idea, but it could very well be a recipe for problems.
