Replacing raw water hose

Tamrow · May 3, 2019

I purchased a new 1-3/4 Inch raw water hose to replace the deteriorating hose on my Yanmar 6LPA-STP engine. Any tricks to get the new hose over the nipples on the water pump and strainer?

Hair dryer or very careful use of a heat gun may soften the hose a bit and allow easier placement.

Soapy water is the best thing to use. I usually use something like spray Fantastic but you could make up a small cup of water and dish soap. Do not use anything made with petroleum. Seeing the rust stains on those clamps I would also suggest you replace those too.

I take a cup of almost boiling water and stick the end of the hose in it for a bit then quickly wipe some hose lube inside the hose and push the hose on. Also recommend replacing the hose clamps. Preferably clamps with solid bands and all S/S, check with a magnet.

As recommended above, hot water and dish soap - when it starts going, don’t stop, get it on. 2x on the clamps; ABA, 316 SS. Available online in bags of 10 for very reasonable prices (1/4 West Marine’s price). Perforated clamps will eventually fail. My boat came with all perforated clamps; I replaced them as they broke until one broke on the raw water hose behind the generator. I didn’t realize it until it filled the generator pan with water. That convinced me to spend an afternoon replacing all of them.

I scrub the bronze with a little muriatic or oxalic acid and water and a brass brush or green scrubby. Cleans it up nicely and makes things a little easier installing the new hose. Hose lube or dish soap and heating the hose in warm water also helps.
