Greetings!

I'm new here so thank you all for your patience!

I have a 1997 Glastron SE 195 w/Penta 4.3 GL and SX Outdrive. Boat runs great and I am very happy. Recently, I have noticed that the tilt/trim pump is leaking hydraulic fluid. The outdrive is still actuating up and down and there is no uncommanded rise and fall of the drive, BUT I am concerned that the tilt/trim pump is on its last legs. It is the old OMC style pump with Penta part number 3855745 (see pic). My questions: 1) Should I just deal with the slow leak this season and worry about repairing this winter? 2) Because this trim pump is no longer manufactured (I believe), what is the replacement pump I can use for this application? I have researched the entirety of the internet and have found much conflicting info. 3) Lastly, should I decide to replace the pump, where can I find the procedure to do so? I presume that I will need to bleed the lines?

Thank you to anyone who is able to assist!

So I located and purchased an OEM trim pump (like the one in the pic) in good condition and would like to replace the old leaky one. I am nervous about switching it out because I'm concerned about getting air into the system. My research says that I can bleed the lines by cycling the trim up and down a few times? Does this sound right? Thank you all for your awesomeness!

Just cycle the system as you said. Power trim or power steering fluid does not foam like transmission fluid.
