Hello everyone. On my Fountain 35 Lightning with bravo shorty sport masters. I just opened up my boat for this season and noticed my mechanical drive and trim tab indicators are acting up. They stick and go up and down sometimes. Not evenly etc... any quick tips to repair this?

make sure nothing is kinked/bound, try lubing things, but it may be time for new 33c cables

Save a bunch of time, order up all 4 cables and call it done.

Do you know exactly what cables I need? Length?

look for markings on the cables...

First thing I would do is run them full up and full down about a dozen times to see if it clears up.
As far as the drives, the plungers mounted on the drives have a spring inside and they get sand/dirt in there sometimes which causes them to stick.
If you replace cables (which can be a pain the a$$) use the TFX Marine ones.
