I have a dbl clutch on the port side and I added a single matching clutch on the outside right next to the dbl.It now looks just like the triple on the starboard side.When you drill the 2 holes out, you only get one shot at this or the clutches will not line up with one another and it will look like you did a bad job at mounting the clutch.What I did to mark the holes was to take a mech. pencil, make the lead come out real far whereas it will reach inside the clutch to the mounting holes. Draw around the holes, remove the clutch, drill,tap, apply cauk to clutch, fasten clutch, clean off extra caulk, route your line, grab a beer, sit back and look at what a wounderful job you just did and drink you beer and smile.Life is good!!!Let me know if you need any other help.Steve,s/v The Odyssey (H310)
