Hi, I would check the front prop lengths for your 300 onto the 200 tdi. I don't think they will fit unless you use a spacer. I fitted a Salisbury on the front of my 110. 200tdi. I had to get a 300tdi front prop as if I remember correctly the 200 sits a little further back than a 300 but with a Salisbury on the front the standard 200 prop is a bit short. I didn't want to use spacers as I was going to do a few trips across Morocco.
