I'm going to take a 1987 Bayliner Capri 1400 with a Force 50 for a drive tomorrow. My concern is the Force engine. A visual inspection shows that the engine looks to be taken care of. It's clean and no marks on the prop. <br /><br />I'm going to run it then do all the checks like looking for water in the lower unit and then a compression check. Does anyone know how many pounds of compression I should expect. On other posts I've read ranges from 100 to 150. On a car I seem to recall if you have less than 100 you should walk away.<br /><br />I suppose I can use the same compression guage I use on my car. I also suppose I can easily hook up a vaccum guage and drive the boat with it on.<br /><br />Just looking for any ideas so I don't make a bad decision. I'm thinking I can pick this boat up for $800-$1000. It will need a new bimini top and new upholstery on the seats and the bowrider cushions.<br /><br />Thanks for any advice.
