Funny story.... when I was 18 or so, my ex-wife (at that time girlfriend) and I got into buying vehicles at police auctions and reselling them. We made a nice chuck of money doing so, and occasionally would buy something to keep. We bought a 17' Larson outboard with a 125 Force motor and trailer for $1200 - sight unseen. We had no idea if it ran, if it floated, nothing. And, I had never even been on a boat before, so the thrill of owning " a boat" was worth the price in my eyes.
I ran out and got a trailer hitch for my 2.2 liter 89 Dodge Daytona and hauled it home. I filled it with fuel, snagged a battery for it and installed it and headed to the boat launch of our local lake. I backed it down the launch, tied it to the pier and pulled the car and trailer up the ramp and parked it. we hopped in the boat, figured out how to lower the motor down, hit the key and it cranked up first try. Nice. Then it stalled. Crap. Hit the key again and it fires again. I let it idle for a few to make sure all the fuel lines cleared out and we start heading out into the inlet out toward the lake. A few minutes later, we look down and the carpet is soggy. I find a switch on the dash for bilge pump and hit it and water shoots out the side. Cool. Problem solved, right? Wrong. We keep going and notice there is an inch of water over the carpet and the hull cover is floating. My ex-wife suggests we go faster to "outrun the water". Made sense to me. Unfotrunately, the Sheriff boat pulled up and pointed out the NO WAKE signs and we were making a HUGE wake. We tell him that our boat is sinking and we were trying to outrun the water.
He asks, "Did you put the plug in the back?"
"What plug?"
We turn around nd head back to the dock, now with water up do about 1/3 of the height of the battery. I am freaking out at this point as I tie it off to the pier and sprint up to the car to back it in and pull the boat out. It struggled a bit, but the car never even spun a tire getting up the boat ramp even with the back end full of water.
Since it was Sunday, the marina was closed, so a quick trip to the hardware store sourced a small plumbing plug for 1/20th the price of one from a marina. Used that boat a lot over the next couple years, pulling it with a Jeep Wrangler and a Jeep Grand Cherokee, but nothing launched it easier than that Daytona.
That boat ended up hers in the divorce, so I pulled it to her dad's work and left it unwinterized in an unheated factory in the winter in Michigan. Revenge is a dish best served cold.
