    Mercruiser exhaust question

    That's what I thought. Does the drive have to come off to plug it back in? It's a Bravo 3

    Mercruiser exhaust question

    I reached out to my mechanic about this. He is going to go back abound what he touched to make sure all is AOK. The speedo isn't working now either. I think it's a petit tube issue since it was fine before the out drive removal. You guys mention the flame arrestor. We are talking about the air...

    Do you guys think this out drive oil issue could cause the strange exhaust sounds I reported?

    Mercruiser exhaust question

    I have a strange one. I have a 2009 Mercruiser 5.0 mpi and it drives a bravo 3 dual prop out drive on my 25ft cruiser. It recently had a major cooling system overhaul which included the out drive being removed. Today I had it out for the first time. At speed (4000 rpm) the boat has a normal...

    Mystery bilge find

    That's what I thought. I know some people send a tube down the dip stick tube to pump out the oil. Maybe it was left in the bilge.

    Mystery bilge find

    Sometimes I wish water would run very high in the bilge if you know what I mean. :)

    Mystery bilge find

    My boat has a 2009 Mercruiser 5.0 MPI with a Bravo 3 outdrive. While in the bilge today trouble shooting a overheating issue, I found this hard plastic tubing in the bilge. Its about 2 feet long and maybe a 1/4 tubing size. I'm wondering if it belongs of if perhaps it was something left behind...

    Cooling orifice tube

    The thermostat was the first item to be replaced. It was done by a mobile mechanic and I have no idea what thermostat he put in it. Since the initial problem it has a new thermostat, new manifolds risers and elbows, a new raw water pump ( mine broke the shaft) AND THEN it went to the dealer...

    Cooling orifice tube

    Thanks.. I have a temp gun. I have confirmed the temp difference from the thermostat housing to the gauge but it's not an easy task on this boat. The temp gauge face leaves at lot to the imagination. "By the gauge" I feel like my temp on the first run was around 200 at running speed. The...

    Cooling orifice tube

    Good morning. I recently had my 2009 Bayliner 245SB, powered with a Mercruiser 5.0 MPI and Bravo 3 out drive, in the shop with overheating issues. They found impeller fins in the orifice tube. Since the repair the boat ran fine without going into high alarm. The gauge shows more heat than I like...

    Mercruiser 5.0 MPI running hot

    The mechanic mentioned that there are two different thermostats that can be used. One is for sea water cooling and the other would be used for a closed system.
