    Mercruiser 470 trim cylinders

    Hey guys, I'm noticing that when I put my trim all the way down, my drive sometimes slowly comes back up on it's own (Mercruiser 470 drive). My oil reservoir is full and I thought I got all the air out of the cylinders last year when I cleaned the old oil/water out of them (water contaminated...

    470 rough running

    Hey guys, finally got my boat out on the water yesterday after having to fix the notorious 470 coolant leak in the engine, rebuild the outdrive, gimbal bearing, etc. Anyway, it ran fine/smooth in neutral idling, but when I put it into gear it ran rough and stalled a few times (was embarrassing...

    Another 4 - 6 question

    I saw someone else post about this and I must ask. converting from 470 to a 160 l6, how much trouble would this be? I can get one for cheap locally but it would probably need a rebuild. Is it worth getting for a conversion down the road? My drive is also a 470 with 1.84 ratio but would I need to...

    Aluminum exhaust manifold

    Id like to put an aluminum exhaust manifold on my '78 Merc 470; but notice that the aluminum ones have one less mounting bolt hole than the cast one I have now. I know I'll need the riser with the reservoir built in; I'm sure it's possible to install this on my engine but what would I need to do...

    Gimbal bearing question

    Pre-alpha drive (#470 drive on a 1978 year boat). I know the manual says to change the gimbal bearing and cartridge all at once but I have done a little research and some folks say to just pop the old bearing out and put a new one in the old cartridge; has anyone changed the bearing leaving the...

    Outdrive oil leaking into bilge

    Hey guys, I have a bunch of outdrive oil that has leaked through the bellows and into the bilge area of the boat (Merc 470 with 470 drive). I have a pre-alpha "outdrive gasket set", it has 3 0-rings, a large round ring and a gasket; will this do the trick or am I looking at something more...

    drive gear oil?

    Can anyone tell me what the gear oil capacity is for the stern drive MCM-470? Also, can I purchase new gear oil from a auto parts store or does it have to be "Quicksilver Super-Duty Gear Lubricant"? I've gone through the manual and cannot seem to find a capacity for the drive. I was running on...

    470 grinding gears / speedometer

    Is the drive supposed to grind into gear when placed in forward or reverse? Also, does anyone know where to hook up the air tube running from the speedometer? I can't seem to find anywhere it goes... This is on '78 Mercruiser 470 with 470 drive. Thanks in advance!

    Steering problems and removal

    First- I am trying to remove my steering cable and have no idea how... It is frozen so it needs to go. There was a retaining clip on it that I took off and I just left the while thing soaking in some PB after being unable to turn any of the large nuts. How does this disassemble so I can get it...

    Trim problems

    My stern drive has been in the up position for probably half a year to a full year. I hit the switch to lower the unit but only one ram was working and the other not. Got the other ram working so now the unit is all the way down. At this point, the gauge says the unit is still all the way up and...
