Noticed in the Yanmar manual that the electric fuel shutoff is an option which is not equipped on the Passage 42 which I'm buying. Has anyone ever added this later? Noticed that I have the engine control panel which has a blank space for the shutoff switch. Also with all the complaints I've read with regard to the oil filter location has anyone installed a remote oil filter to improve this access. I'm getting a quote from the local Yanmar people but it's always nice to get first hand advice on concerns or options. Rick
