Thread subject: Whaler Central - Boston Whaler Boat Information and Photos :: Tilt n Trim on 89 Yamaha 150 leaks

My reservoir loses trim fluid very slowly. The source of the leak appears to be around the threading for the pigtail located at the bottom of the main assembly housing (#39 in the attached pic). I replaced the pigtail, but the leak continues.
Has anyone experienced this? Short of replacing the assembly, what can i do? Thread sealant? Thx.

I would try thread compound or teflon tape.

I had one do that and turned out to be a twenty five cents o-ring on the fill screw.
