I have recently changed my boat and new one has a Volvo penta 5.7GS motor in it. The past few months it's been having an intermittent starting issue where sometimes when I turn the key I just get a click. After a few attempts it fires right up. Sometimes it will just start first turn. I had a similar problem on my old boat that was fitted with a mercruiser 5.7EFI. I changed the slave solenoid on that and all was good. I am just wondering weather Volvo use slave solenoids and if so where would it be located on my motor? Can't fine any reference to them online. Thanks in advance for any help you may be able to offer me!
