4,3 Mercusier MPI Alpha 1 Gen 2 ......well had an incident that my Drive and transom assembly had to be replaced .So the work was done at an authorized mercrusier dealer. They called me and told me the boat was ready -I had to wait about 3 days until I was able to pick the boat up. When I got there the bilge was fill of oil and the oil reservoir was empty . They said we need to check it out and will call you when its ready. They called a week later said all fixed. When I went to get the keys I saw the tech and asked what happened he said the they installed the quick disconnect that on the hose that goes to the oil reservoir on a bolt not the fitting ??? Well when I statrted the boat there was a winning sound coming from that drive -called out the tech -he said sounded normal -also said it needed to break in? well I shut that engine off and started the port engine and proved to him how much louder the new drive was -he said run it 10 hours and bring it back. I get 20 minutes out and the alarm goes off -the drive oil reservoir is empty -luckily I had a quart on board and filled it up and drove anther 20 minutes to my dock and the oil reservoir was down about 1-1/2" . So there is no way they could of filled the drive per mercusier procedure -The winning does get louder has you go faster . Is the brand new drive toast? The shop wants to take the boat back to fix it but not want them to tear into a brand new drive.What a mess!!!
