Aluminum catamaran pontoon project help

I just bought an aluminum catamaran pontoon project boat. I have been around boats my whole life but not a builder by no means. I was wanting some information about this pontoon due to the unusual toons. The boat also came with a Yamaha 50 four stroke that is separate. I can't get info on boat or motor due to the owner passing. I know the general process about restoring the boat that I can handle. I'll have to get help to put in wiring, mounting and so forth. Should I go ahead and mount the motor or is ur feasable to take to a mechanic detached to see if it is worth it. I'm going to attempt to post pics from my iphone with little luck but i can email pictures them to help also. Thank you for your time guys.

 

What's unusual about the pontoons?

 

They are aluminum large catamaran toons. I have never seen any like that around here and can't find any information about the specs. I can't figure out how to put my pics on here from my iPhone or I'd show them.

 

They look very similar to the Sylvan RPT hulls. Not quite as much lifting surface, and I have no idea what that damn is doing in the middle of the hulls.

 

Yea that's the closest design I can find but nothing on the box design. What part in the middle?

 

That triangular shaped thing in the middle at the rear of the boat is the mount for the outboard.

The hulls are shaped like that so the boat will plane, which I have always found absurd in a pontoon boat, but to each his own, I guess.

If you look at the stern of the starboard pontoon there maybe a Hull Identification Number, assuming it was made after 1972. The first three letters indicate who the builder was. If you can find it post it and we'll look it up for you.

 

Ok thank you I'll take a look. I imagine the load capacity would be better since the size takes up most of the space
