    470 4 barrel conversion, one cylinder missing

    Can you put a temporary fuel pressure gauge inline just before the inlet to the carb to verify fuel isn't the issue? I actually had one for a while installed permanently using a 3/8" inverted flare tee and adapted the middle of the tee to a gauge thread, but the weight of the tee fitting and...

    Super stuck gimbal bearing in Mercruiser Pre-Alpha -- is there a clip?

    The snap ring ears should be pretty obvious if you have one. What tool are you using to try to remove the gimbal bearing? One tool that works well is a rear wheel bearing puller. Malllory makes a gimbal bearing puller tool # 9-79820

    need help mercruiseris

    did you put the drain back in the heat exchanger? The engine should have coolant/ anti freeze in it. If so I'm betting on the drain plug. There are two in the heat exchanger, the AFT end one is sea water one... that's the one that gets removed to winterize the engine.

    Merc 470 running hot

    Welcome to the 470 club! :thumb: The engine circulating water pump almost never fails. I run the same model and don't budge off 160? all day long with the 4" exchanger. My mind is thinking drive related. Your port engine runs at what temp? Did you do just the impeller in the drive or the...

    Merc 5.0 falls on its face

    There is a MCM 200 and it is a GM 305 but they stopped making the 200 in 1987. In 1988 the GM 305 was called the 5.0L Not really a big deal but the engine would probably be an '85, '86 or '87..... depending on Serial # see the chart

    OVERHEATED BOATER

    pull the drive back off and run the engine off a garden hose by sticking it in the water inlet in the bell housing. You should be able to run it that way..... or on muffs..... forever without overheating. (Photo by Fishermark of his)

    Mercruiser 170 Closed Cooling Issues

    Man to keep pulling the head off and not have it checked out at a machine shop is crazy. Loss of coolant has several possible causes, http://boatinfo.no/lib/mercruiser/manuals/mercruiser8.html#/244 The three I'd try testing could be: Cracked or warped head Improperly installed gasket...

    engine, lower unit or starter?

    Usually a burnt rubber smell is an indication of a failed engine coupler. You can run the engine with the drive off, stick the garden hose in the water inlet in the bellhousing and try and fire it up. Just make sure it doesn't fall out. Photo of Fishermark's bellhousing.

    Upper Shift Shaft Seal help, New Loose Twin Seal Style

    I used a piece of either 1/4" or 5/16" threaded rod, some washers and nuts. (can't remember the size, but it has to fit inside the bushings). With the shift shaft out, inserted the rod through the bottom bushing and the top bushing. put a small nut on the rod above the top bushing, and a nut...

    Alpha 1 overheated badly

    The two seals your referring to at the bottom of the upper unit... The bottom one pops out from the outside, just stick a screwdriver or seal puller and pop it out. and tap the new one in there with an appropriate sized socket. The upper seal goes in from the inside. You'd have to pull the...

    470 Engine turns over but wont start? 1977 Mercruiser

    Dwell is the amount of time in degrees that the points are closed. Changing the gap causes a change in dwell. More gap = less dwell and vice versa. Changing dwell also changes ignition timing, but changing the timing does not change dwell. Dwell should be between 28?-34?. You have to adjust...

    No water circulation

    You have to shift the shifter to forward gear so the drive is in forward. You don't have a transmission you have an outdrive. If your shifter is stuck.and you can't shift between the gears then remove the shift cable off the engine that goes thru the transom to the outdrive and push on the end...

    Pull the drive off and run the engine off a hose. Stick the hose in the water inlet in the Bellhousing and let her rip, just make sure it doesn't fall out. The water inlet inlet is shown below in Fishermark's photo.. The left side opening covered in grease. To be safe... you will need to do a...

    Mercruiser 470 Delco Distributor weights & springs

    There is also Mr. Gasket 928G. spring kit without the weights. I think I would re use the original weights. General Motors use to like to make the same part work for several model cars, easier to produce... I bet the springs are no different. You could check your advance timing with an...
