TOPIC:

Not really "tackle" but certainly important. I made the new bunks last weekend and hope to drop the boat into Pine this weekend and install the bunks. Hopefully the ice is gone by then. Once that is done And I give the boat my annual spring shake down on Pine I'll be ready for the big pond.

Nice job Baron, I was thinking of doing the same thing. What type (kind) of wood did you use? Rudey

I replaced bunks on my bass boat a long time ago and just used green treated wood.

I used the green treated also. When I replaced mine a few years ago.

After quite a bit of research I went with Douglas Fir. Using modern pressure treated lumber for bunks is supposedly a bad idea. Apparently the liquid used for the pressure treatment is very corrosive to metals including Aluminum. Over time it can cause hull corrosion is what I hear. That being said Eagle Trailers uses some type of Marine Grade Blue Spruce and the ultimate bunk wood would be Cypress. Cedar is also a good choice IF the bunks are vertical. Cedar is very resistant to rot, but it isn't very strong and prone to cracking. Douglas Fir seems to be a "good" choice from my research so I went with that since the other mentioned materials aren't readily available from a local source. I bought the lumber locally and ordered the carpet online from a place called "Bass Boat Seats". The carpet is nice and I was able to order a 45' roll.

Thanks Baron for the reply, you answered all the questions I have at this time. I may have more when I start the project, but that sounds like a job to do this winter in my shop. Rudey

Interesting about the treated lumber - did not know that. Good to know!

Baron I heard the same thing about using the wrong wood. I also saw pictures of alum. boats that looked like you had put acid on them. They actually had holes thru the alum.

I rebunked my trailer a couple seasons ago and used treated lumber. My boat is fiberglass so I don't think that's an issue. I'm not sure how much an issue it would be even on aluminum since you are putting carpet on the bunks which would-should separate the boat from the wood. The issue is the copper salts used to treat the wood. When you rebunk a trailer, especially with treated lumber, use copper nails to secure the carpet to the bunk. Steel nails will dissolve PDQ. I purchased stainless steel lag bolts to hold the lumber to the supports, as well. Most of the original lags were chunks-O-rust by the time I replaced them.
The exciting thing was I didn't have a lake handy to off-load the boat while I worked on the trailer. So I jacked the boat up and pulled the trailer out from under and left the boat sitting on Jack Stands.

Wow I have heard of this happening but that's the worse example I have ever seen
To a little or a lot dont matter NEVER USE GREEN TREATED WOOD IN OR ON OR AROUND ALUMINUM BOATS
I have seen guys replace floors with this stuff and the chemicals leach out and eat holes in the bottom
Also guys replace bunks on trailers with treated lumber and all of a sudden the bottom of boats look like it has salt water barnicals growing on it EATS RTE THRU THE HULL
NEVER BUY A USED ALUMINUM BOAT WITH ANY GREEN TREATED LUMBER INSTALLED IN IT OR EVEN ON THE TRAILER BUNKS
If some one selling a boat starts telling you they re did this or that with good treated lumber
RUN THE OTHER WAY there is probably already damage where you can not see it
The sad part some boat manufacturere used it on brand new boats it did the same thing
Guys I am not going to name names because I am not sure what ones and when what models ect
It was a effort to make wood transoms last longer some sealed in the wood with epoxys but the chemicals leach out around any screw or bolt hole
It just never a good ideal to put these chemicals any where near a aluminum boat
If you have a aluminum boat with corrosion problems and the boat has been gone over by a competent NMEA electrical tech there is probably some treated wood in it some where
Typically it's just the green treated variety I don't know the exact chemical content that causes this but have seen the results many times
Best fix for any problem is not to have it in the first place
