Hello everyone,

I have a 2005 SX230 with the original MFI Tandem axle trailer. Im in the process of buying all the trailer suspension parts because of rust. I pretty much have located all the parts, but I'm confused on the size of the axle. I do not have access to the boat at the moment but I'm trying to order the parts online now. I know there are three different types of measurements.

A. Spring center measurement ( which i was able to measure at 74" )

B. Outer flange measurement ( Which I wrote down as 89 ) but I believe i wrote it wrong, I believe it is be 79" since the spring center is close to the axle flange area but for some reason I wrote down 89". I don't like to have a doubt in my head, although I'm pretty sure it is 79-80"

C. Outer Hub face ( which I do NOT have that measurement ) tires were on and its difficult to measure since I was by myself

does anyone have this trailer that has changed the axle that might know the measurements? As you can see in the pictures the suspension is badly rusted and on Port side, the spring assembly is even missing. The trailer is sitting on the axle itself on that side.

And has anyone used the Dexter Axles that are being sold on Trailer.com? Im wondering if they are resistant to a Saltwater environment, because I don't see them selling any axles this size galvanized.

Any help would be greatly appreciated
