Average Customer Review for Circulating Water Pump - Sierra
Based On 2 Reviews
Not an exact fit. by a CustomerJuly 27, 2011
Had to shim out the 3 gang pulley (power steer., impeller, water pump) to clear the new circ. water pump. Also had to remove the impeller pump bracket to allow clearance for the hose running from the thermostat housing to new circulating pump housing. Tripled time needed for simple replacement of circulating pump.

TIMING by Jeffrey - Monarch Beach, CaliforniaSeptember 23, 2012
OUR CUSTOMERS WERE SUPER UPSET, WHICH LED TO TWO BAD INTERNET REVIEWS ON THE INTERNET FOR OUR SHOP NOT IBOATS AND WE HAD NOTHING TO DO WITH IT! THANK YOU IBOATS!!! WE HAVE BEEN IN BUSINESS FOR OVER 40 YEARS AND THOUGHT WE WOULD USE IBOATS BECAUSE OF PRICING. WHY DID IT TAKE 2.5 WEEKS FOR PARTS TO GET TO US? PRICE GOOD, BUT NOT WORTH IT IF DONT HAVE TIME AND WE ARE A REPAIR SHOP. SUMMER IS ALMOST OVER. WE JUST CAN'T FIGURE OUT WHAT WOULD TAKE SO LONG TO PULL AN ORDER OR PART PUT IT IN A BOX AND SHIP IT TO US ON THE WEST COAST??? 5 DAYS OK BUT 2.5 WEEKS? OUR CREDIT CARD HAS BEEN GOOD FOR 40 PLUS YEARS?????????? WE LEARNED OUR LESSON AND WILL PAY MORE TO THE LOCAL DISTRIBUTORS JUST TO STAY OFF THE BAD INTERNET REVIEWS. IT WILL KILL YOUR CUSTOMER LOYALTY. THANKS FOR LISTINING JEFF MONROE RACING

workes great by Bryan - Stafford, VirginiaSeptember 30, 2013
Just replaced the original water pump on my 1989 maxum 2300 (5.0 motor) this was the best price i could find on a pump and the pump fit perfectly. Took the boat out for a trial run after a lot of work and the water pump worked great.
