I’ve worked with stainless-steel-braided hose on enough boats over the years to know that its benefits outweigh its drawbacks. The benefits come in the form of higher bursting strength and longer life. We’ve talked about this before in Replumbing Your Used Boat Engine. It looks better, too.
The drawback is that the stuff is difficult to work with. When you cut the hose, the frayed stainless braid presents lots of needle-sharp finger-stabbers that have to be managed, and the process often gets bloody.
Then, with steel- or nylon-braided hoses, there is the matter of mating the aluminum female hose fitting to the end of the hose. It used to be that you had to have a shop do it for you.
That meant measuring everything, cutting the bulk hoses to the right lengths, then driving back to the shop to have them attach the female fittings to the hoses, then driving back home to put everything together. Oh what fun.
It turns out that Koul Tools in Lake Havasu City, Ariz., sells a simple tool that lets you do the whole job in your driveway.
Offered in AN sizes from -4 through -16, the Koul Tool couldn’t be easier to use. Place the female fitting into the tool, clamp it in a bench vise, insert the hose and push it in while twisting it for a few revolutions.
Then, remove the Koul Tool from the vise, and the fitting and hose pop out as one piece. No more frayed ends or bloody fingertips.
There are two nifty videos at Koultools.com that shows how easily it works.
As any boater knows, fluid transfer is critical in a marine engine. But hoses and fittings can wear out over time and become a source of concern, especially if you’re buying a used boat and don’t know exactly what it’s been through or how it’s been maintained.
By replacing those hoses and fittings at your leisure—rather than when you break down—you can focus more on enjoying yourself rather than constantly inspecting your bilge water for oily residue or nervously checking your gauges.
And with the new hoses and fittings on the market, you can really dress up your engine compartment—likely for less than you might think.
