I recently aquired a 1987 Bayliner Capri 1950 Cuddy. it is in Excellent shape. It has the Volvo with the 275 lower. I know that it was winterized at the end of the season. My question is ....Is there a fuel shut off valve? I cant locate one at first glance.....the motor turns over but just wont start. sounds like it's out of gas...but there is plenty The engine is the AQ131A with 275 outdrive
