Help identify this boat model

[RedneckCatter]

Im looking to do some mods to my 18ft Starcraft. Like trim down the engine compartment as its way too much space, Add storage in the floor and along the sides. I know its a 1978 Starcraft Aluminum with merc 470. But what model is this boat so i can try and find specs. So i dont drill into the fuel tank for instance. Yes if i cant find any info ill do it the hands on hope nothing goes wrong way and drill holes to see where the fuel tank ends. Whoever did a previous job either removed, covered or painted over the data plate and i can not find it.

It looks like a Super Sport with the much desired V-5 hull. They are great boats, although I have never been in a inboard/outboard version, only outboards. Hope this helps.
