MDI

I ended up talking to several people yesterday that know tons about the problem I'm having with that part on the engine (called an MDI). My engines are 2016 Volvo D2-40's. It's a technical problem that Volvo hasn't figured out how to fix even though they've had the problem for years. I spoke with the manager of Dream Yacht Charters here. He's been through many of these on his boats. A month ago he had a team of 5 people from Volvo engineering here for a week to try to resolve the problem in his fleet of boats with new engines but no success. He continues to be plagued with the problem.
I also ran into Michel from the French boat "Spica", which was part of the rally. He has a new Outremer 45 and has had the same troubles. He was carrying a spare MDI and needed to have his replaced here in Martinique as he could no longer start one of his engines. They have a switch wired in to allow them to start their engine if it fails again. I was planning to do the same.
Now that I know how to work around the problem I'm not worried about it anymore. It's only a pain because I need to go into the engine room to start and stop the engine. I'll solve that next :-)
