Needed to modify
by Larry from Carlisle, Pennsylvania on October 13, 2014
Part seems s y enough if not put under tremendous stress. I think I will need to support the garden hose to a degree. Needed to modify by cutting off one of the ears on the flusher as the opening was not wide enough for my Yamaha outboard. A small clamp can do double duty of holding up that end and better support for the entire unit. Service from iboats was very prompt. Service gets 5 stars..........

Does not fit
by Ervin from Port Orchard, Washington on September 19, 2013
Thek physical design of this flusher is excellent, however, it is made of hard brittle plastic. Your cavitation plate must be consistently 1/8" or less or it will not work. It does not fit my 2003 9.9 Merc. I did not want to force it on for fear of breaking it. I am going to try and make it fit by pushing it on at the same time heating it with a propane torch and try to expand the slot to fit my engine. I offered to send it back and iboats made me a deal I couldn't refuse. They did me right.

Broke during second use
by Jeremy from Tuscaloosa, Alabama on May 12, 2013
I got it to fit the base of 30 plus year old engine the first time it fired up and the flusher stayed on and water flow was great. The next day my motor cranks second pull, then there is no water coming through the pee hole. Look down and shut the motor down and find out that the fitting for the hose has become disconnected. But not from the hose itself, but the fitting on the flusher has broken off inside the flange. Two uses then it breaks. Not what I expected, delivery was as promised, part did not exactly fit my engine, breaks second use. I will not purchase another part from your company for a while. I will look locally from now on.

It works, but fit is too tight
by Dean from Honolulu, Hawaii on January 24, 2012
The motor flusher works, but is hard to fit on my 9.9 hp Mercury 4 stroke. I'm thinking of shaving off some of the plastic to make it easier to slide on.
