I made boat lift guides out of some items laying around the garage. Galvanized fence post, treated 2x4x10's, and trailer carpet. Now the issue is connecting it to the lift cradle. I want drill holes through the poles and through the cradle. Is this possible? Is there a reaction between the metals that could corrode?
Can I drill through a boat lift cradle?

I'm not sure about your question, but my lift guides are clamped to the lift cradle.
With yours being round, you could use a u bolt and a plate on the other side.
Are you sure you want carpeted bunks? My lift has these now and I want them off. They leave marks on the hull and they peel stickers.
I want to swap to poles with PVC over them.

How big of a hole and where it is matters - a small hole in the middle - not a big deal - a large hole near the bottom of the cradle - not a good idea.
U bolts is the correct answer in regards to corrosion - the aluminum may get some surface corrosion and galvanized hardware should be used > stainless as the stainless may gall.

Thanks for the replies. I should have mentioned I have a very old shore station from the 90's Its a classic!
I was struggling to find a U bolt that was long enough to reach across the I beam. I never thought of the PITA it will be to wipe down the sides. Well you just made my free project get a little more interesting.

So the old shorestation with the I beam front and back cradle pieces vs the newer v shaped ones? That is old.
I beams are generally ok to drill in middle (aka web). Structurally you wouldn’t want to drill at the ends for a certain amount but middle is ok. You obviously want the ends. Do not drill top or bottom (flanges), that is the strength. The middle / web is really a spacer....
You will be drilling small holes so likely ok.
I’d still rethink and bolt on pipes of some sort vs side bunks.
