I'm new to the jet boat scene. I got to drive a friends last weekend at the river and was instantly hooked. So 2 days later I drug one home .its a 1971 Mariah with an Olds 455 bored .060 over and a Jacuzzi WJ jet.  I can't find much about the Mariah I was drawn to old school body lines. If there anybody not knowledgeable than me any info would be awesome!
