The iboats forum moderators are excited to announce that at this time it appears the iboats forums posting pictures function is working once again. Though we cannot promise for how long, we're hoping for indefinitely.
I can't seem to be able to loosen the fill screw of my 90hp E90TLCUR tilt/trim
to add fluid. I do have a large flat head screw driver and a wrench that I tried. I don't think it's a good idea to heat it, or can I? Impact tools?
I have about the same motor myself and I'll assume your unscrewing the large screw head near to top of your trim/tilt. I would suggest you spray some penetrating oil first and let it sit for a while. Heating it may not be a good suggestion as it could cause a lockup.
I would try the penitrating fluid, then a manual impact screw driver, it works wonders. I would not beat on it excessively, a good clean hit to the impact should work.
