    2005 Honda 150Hp 4 stroke Opinions

    My uncle is looking at a deck boat and it has a 150Hp Honda motor on it. Are these as reliable as their cars? I know this is basically a Honda Civic engine. What should we look at on this besides compression and a test drive. The boat is 8 hours away, so this will be a one trip go-no go...

    Thermostat Removal

    I am working on this motor and have 2 questions: 1. What size allen/hex wrnech is required to remove the oil drain plug? 2. I got some very strange compression readings on this 4cyl (148, 148, 137, 180) I have never seen one so spread out, but I don't service to many Yamaha's. How bad is...

    40HP Mariner shift linkage

    I am working on a 1983 Mariner 40HP, 40EL model. The lower shift linkage pulls out of the top of the gearcase. It looks as if there is a keeper pin that is sheared off at the bottom that is supposed to keep it from coming out of the gearcase. Obviously the motor is stuck in reverse. Is there...
