I have a '98 yammie 115 that has been vibrating a bit on plane typically when it's trimmed down. I had the prop rebushed assuming that it would come with a new hub. When I tried it out, the vibration was better but still existant to a lesser degree. My brother just bought a new 90 Yammie and the shop said he had to tourque the nut on to a fairly high inch-lb. I've been running mine loose as it came that way but is this correct ?
