I’m on my second jack right now, and I just found out it’s seized when I went to take out my boat for the first time this year. The first jack lasted about 3 years, this one only lasted one summer. Unfortunately due to my trailer design, boat, and just the slope of the launches, I can’t avoid submerging the jack.

I’m about to buy another jack so I want this one to last. I paid for a high quality one (1500 lbs, $130) last spring and it’s already toast.

how and where? mine didn't seem to have a grease nipple or anything. And the top of the shaft is pressed on. Are you just packing by hand?

Hmmm, So the trailer tongue gets submerged???

I’ve never seen a trailer tongue or Jack go under water.

Mount it further forward?
Extend the tongue then mount it further forward?
Buy a higher lift Jack and mount it above the trailer tongue?

Hard to suggest much more without a decent photo of the trailer tongue.

I can't figure out how I would get mine wet.

I'd have to see a picture of yours.
I don't have a grease nipple either.
There was a black cap that I would pop off and add grease if I wanted. I'd just stick the grease gun nozzle in and pump a few times.
Mine never goes under water either.

so this was the original on my '04 (?) trailer I bought used in 2016. It's been replaced because the marina broke the wheel and got me a brand new assembly 3 years ago. So it was 21+ years old and still good.
