    looking at new prop- are hub kits the way to go?

    I have a 1984 Mercury black Max 150 and I want to change the pitch from 19 to 17. My old prop is a quicksilver 48 16316 A5. The new prop I am considering is the quicksilver silverado but it says I need a hub kit. So is this the smart way to go?

    water pressure fluxuates on throttle 150 black max 1984

    My engine is a mercury black max 150 1984. My last trip last year I was having water pressure and temperature issues and figured I needed a new impeller. Last week I replaced the impeller with a new kit and started it today for the first time. Water pressure seems good at idle around 12-13psi...

    Where can I mount my voltage regulator for a 1984 150?

    I just received a cdi voltage regulator and I was going to replace my rectifier but the voltage regulator is a lot larger than the rectifier and I don't think I can mount it in place of the rectifier above the power packs. I read a post that described a location on top behind the flywheel...

    storing a trailer on blocks over the winter

I have read the best jack points are right at the axle near the tires but should I...

    1984 150hp no tach-high voltmeter reading

    I just ran my 150 black max last weekend for the first time this year and noticed that the tachometer was not working. I also noticed that the voltmeter was reading extremely high, not pegged but almost 16volts. The last time I ran the motor everything was working and have never had a problem...

    Temperature sensor location

    I read last season about installing a cylinder head temperature gauge to provide added security. I am getting around to the installation and had a question about the location of the sensor. I realize this is not the ideal setup for accurate cylinder head temperature but it's the best I can do...

    Idle stabilizer-erratic tach

    I have read where most people suggest removing the idle stabilizer, especially if it is causing problems. While replacing my stator, I noticed the red wire from the idle stabilizer shorted against the switch box. I just removed it as people suggested. <br />While running my boat last weekend...

    flywheel removal-stator replacement

    I have a 1984 Mercury 150 and I need to replace my stator. When the flywheel is removed, is it splined or keyed to the crankshaft?<br />The book says I need to set the timing after replacing the flywheel. Do I really have to do this?
