Yes mumbles, it goes right over the screen intake behind the prop. The metal clip holds in on the exhaust port behind the water intake. Pretty handy tool, since I can use it on motors up to 2000 using the older style 2-piece gearcase, such as the 28 SPL….basically usable from 1954 fastwins (15hp) right through 2000.
Not to ramble on but compared to mercury, I still shake my head at how much stuff on OMC’s can just be reused. Probably a big reason why they went out of business. Folks didn’t have to keep buying new motors/tools/parts every 3-5 years because they just kept making the same thing for decades. At least mercury thought ahead for ‘planned obsolete-ness.’
