Stop Leak Additive for Power Tilt and Trim?

[natemoore]

F115 Yamaha. I believe the leak is caused by one of the several o-rings sandwiched between the gear pump assembly and the trim housing. It's not leaking from any of the rams.

Has anyone ever successfully fixed a leak using a product like Lucas hydraulic oil booster & stop leak or any of the power steering/transmission stop leak products? I'm not looking forward to those bolts breaking off.

Also, I hate having to pay $6 for a tiny o-ring.

I've used Trans-X with success. I used it once as a temporary fix and completely forgot about it until several years later when I sold the boat.
