Not an exact fit.
by a Customer
July 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, California
September 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

Excellent
by Gilbert - Presidio, Texas
February 02, 2012
Great customer service support on ordering correct part. Product shipping excellent received quicker than expected. Installation was a breeze fit perfect. Took boat out a week after installing it and performed flawlessly. Highly recommend product however you might want to check with Iboats product specialist to make sure you are ordering the correct part. They are very knowledgeable.
