I just found out the the link between my teleflex and Yamaha 90 hp was mounted with an incorrect screw.<br /><br />The "tiller" hole (actually there is two, I guess that the one placed in front is for twin mount) is threaded. I now have a M8 bolt which is to small for the thread, it can move sideways and doesn't use the threads.<br /><br />I tried to fit a M10 bolt in the hole but it is to large! The hole is about 8.5-9 mm but there are no M9, so my guess is that might be a UNC or special threading.<br /><br />Do anyone know the correct thread size?<br />
