Sierra 18-3575 Marine Circulating Water Pump

i like

My worst fear came true the pulley rubbed when installed but it's a simple fix find longer bolts add lock washers behind the pulley although the. 5/16x24 hex bolts aren't common I found allen bolts instead.

My last pump started leaking. Purchased from these guys cause they had it in stock for a much cheaper price. Installed easily and fits perfect. Works great too.

looks great mounts great but when u remount v belt pulley on pump it rubs against pump on my Volvo but it may fit your boat fine I had to order original eq

Item as described. Shipped fairly quick. Perfect fit on my 1979 Mercruiser 140. Slightly different casting "shape" than the original but functions perfectly and no mounting issues or problems. Good aftermarket product and substantialy less exspensive than an original Mercruiser replacement. I also use Sierra impeller kits with no problems.

does not work for 99 mercury 3.0 even though model number matches description. just like all the other bad reviews, the pulley rubbed against the part where it goes from being round where the hose attaches to being flat. i didn't find out until after putting everything together, wasted a good oem gasket too, had to buy another one and original quicksilver pump. don't waste your time and money with this one. if the casting was slightly thinner, i'm talking like 1/8" it would work, lesson learned

Saved me Major $$$$$ for my Boat

As advertised! A great product!

Works great!
