Re: Boat Identification
Orrion was only in business from 1973-1982. Do you have a model name for your boat? That would help in finding specs. I couldn't find a 15' I/O model.
Do a Google search for Orion Boats and you'll get to the listings here on iboats.com for them, where they go model to model with some specs.
Bottom line is that you won't find any replacement parts for the boat itself for sale. Replacement parts for the engine and drive are another matter, although even some of those may be hard to find.
There should be a capacity plate somewhere on the boat, along with a Hull Identification Number plate.
Boat companies that are out of business are a dime a dozen. What parts do you need?
