Bunk replace

[ffishman]

I went with Red Cedar. I hope that was a good thing.

I ran a EZ Loader trailer under my 25' Sea Ray for 23 years with tires and lubing bearings as the only service needed. I did have a bearing go out 1 time but caught it before losing tire. I have also had good luck with Trailmaster and Eagle trailers. I am a firm believer in getting a trailer rated for more weight than you ever haul.
Have a great day.

I've got to ask, why is treated lumber bad for am Aluminum Boat? will there be some sort of reaction??

[Bigredmf]

Some pressure treated wood is/used to be copper/arsenic treated

The copper can react with aluminum

You MIGHT be ok with modern pt but I think boat manufacturers can still use the old style pt

They wanted to stop arsenic from leaching into the ground from copper-arsenic treated lumber in the late '90s, so they replaced it with alkali-copper-quartrenary or ACQ.
Aluminum reacts strongly with the ACQ, that can corrode most metals very fast under the right conditions. Any treated lumber labeled ACQ or AC2 can only come in direct contact with high quality stainless steel or double dipped hot galvanized fasteners.

Great helpful info. I believe I will use cedar.
Thanks!

Mil,
I have also used cedar for my bunks.

But, be aware that cedar is not as stiff as fir. In order to use Cedar, you need to use a larger size, compared to the size of a fir bunk.

Be safe

I am with REW on this one ... cedar is only 2/3 as dense as fir ( untreated ).

This indicates that you might have a problem depending on how heavy the boat is. your most likely will need to almost double the thickness with cedar and it still may take "a cast" after a while.
