Installing second engine on boat

I currently have a 35hp engine on my other (hard) boat. This is really too small for it - apparenly it has two 100s on it before i got it.
Anyway, have been blessed with a matching 35hp for an amazing price, which I picked up today. This should at least get it on the plane.....!

Now heres my question: How close together should the engines be mouted....
And, where can one buy a drag link suitable for linking two engines online (so I can get an idea of prices before the local shop rips me off). Are all links a standard length (this goes back to the first question).

I reckon you want the engines mounted as close together as possible without fouling each other when turned. Closer together means if you have to run on 1 the thrust won't be so assymetric, plus you're less likely to ventilate the outboard one in a sharp turn.
