I bought a 04' Tracker Pt about 10 years ago, as of last year the power trim sometimes doesn't want to come up and usually when im headed for shallow water, lol. when i try to trim up, it bounces like its low on hydraulic oil. I am hoping its a small leak and topping it off will cure the issue. So seeing this is my first boat with power trim what type of fluid should I use? and I am guessing I need to support the engine when it?

Thanks Tom
