Engine central, and mount battery & anchor etc on the starboard side. Height will depend on your gearcase, propeller, and boat use

Talking Height of Yamaha

This what I'm going to tell you would give you a half decent height With a standard get box The bullet of the gearbox on the Front Which is the opposite side to the prop shaft If you didn't know If you run that 3 inches below the bottom of the V You should be quite safe To do this get a piece of timber To use as a straight edge on the bottom of the boat And measure down to the Bullet On the gearbox Make sure it measures 3 to 3 1/2 inches No less Hope this helps I've set many boats up now and They all go very well and most of them have standard gearboxes And make sure you fit yourself a water pressure gauge on your engine Run yourself a Yamaha Standard stainless prop they are Very good prop And will give you a good ballpark figure of where to go I recommend about a 25 To start with Hope this helps many thanks Keith
