I have a 1973 Johnson 65 HP and I'm trying to find a impeller kit with orings and seals, but I'm having no luck. I have found the impeller just by itself but nothing else with it. I need the seals as some of mine are looking rough. I found this kit but everywhere I see it it says that its only for 1971-1978 50 hp Johnsons. All the parts look the exact same, which is a first also. Please any input would be helpful. https://ww2.iboats.com/Johnson-Evinrude-OMC-384956-replacement-parts/dm/view_id.461821
