Back in 1981 I had a small 18 foot modified V bottom speedboat with a 260 Mercruiser. the only info I have on the manufacturer are the letters GMC on the sides near the transom. I saw 1 other make like this and it was a outboard . Anyone with any info. THANK YOU! By the way the boat ran about 65 MPH. But the water better be darn smooth.

Just thought I would re-introduce this thread for any new people that might have info THANKS

The first three letters of my hull # is GMC it is global marine corporation the model of boat is an infinity. The only info i can find on these boats is that they were made in georgia i think and went belly up around 1994. I know of two other boats like mine. When i was trying to find info on mine i think i read or saw an ad for an 18 foot. Jlay

What type of boat is your's do you still have can i have more info thanks
