1999 Yamaha f100 tilt and trim

leadheadleadhead Posts: 90 Greenhorn
Have a 1999 yamaha f100 that i am having issues with the tilt and trim. Was using it Friday and it seems like it wasnt working while i was underway. Then it started working fine i think. Loaded the boat tilted it up about halfway and brought it home.Went to try and tilt it today and it is like half way up. Will go up just a little and down a little. Not enough either way to be able to use the boat. Any suggestions? Could be low fluid maybe but not sure how to check or fill.. The motor seems to run fine. Any help is appreciated. Thanks

    The symptoms you describe is usually low fluid. Tilt the motor up and lock it out. Then look on your trim unit for a weird shaped nut. Should be up high on the unit and should be able to remove by hand. Add fluid and operate several times before going to the water.
