Yes, I went with the TM, so far it has worked great. I did just install one unit at or close to the bottom of the V. Whats nice about the Pursuit hull is the step/cavity that is on the transom, so the ducer is actually installed quite a bit forward of the engines, and there is no concern about spray from the ducer, like I have heard some others have. It holds bottom for me all day long, at all speeds, and has great detail. I am not sure if your hull on the 345 is the same, but I would imagine it is similar. If it is anything like mine, it should perform great as a single GT51.
