@Pete. You need these on Great Adventure…. 😀

5500 obo, this is some nice stuff to bring a trs boat up to date with bravos.

Where are you located?

Located in Massachusetts

Will you separate the pair.

how old are those boxes and when did you get them?

didn't know stelling was making those boxes or were those the prototypes.

I will not seperate. These are older boxes, stellings was making them for some time before trs became obsolete. They are also adjustable, allowing you to raise the "X" dimension without moving your engines. It's works well when properly setup, i personally know someone running this exact setup with great success.

I have had them for a few years and never used them, was considering using them on my trs boat to convert to bravo but ended going with Konrad's. This is some nice stuff that is becoming very hard to find especially in this condition and complete.

Stelling is out of biz for a while. They did make the TRS to Bravo conversion boxes, but I don't think they sold very many of them. I have only seen them listed for sale a few times over the past 10-15 years
