    Priming a Rebuild Engine

    They work great. If you crank the engine over with the distributor out your have to bring it back up to TDC for #1 on the compression stroke. You can also set the timing tab at 8°F BTDC or whatever your initial timing is, when you drop the distributor back in, set it so the rotor is pointing...

    Alternative to drilling your alignment tool to install gimbal bearings

    I just want to comment for anyone who may reference this later, that the 1½" pipe isn't large enough in diameter to drive the gimbal bearing in alone. To use a piece of pipe alone, I think it takes a 3" diameter pipe to grab the outer ring of the gimbal bearing, which is what I've done in the...

    470 swap to 4.3

    Blown as in a rod is sticking out the side of the block? Or a blown head gasket?

    Engine dies going into reverse

    Full impeller kit in the drive also; shift shaft bushing/seal upgrade if it's the older style. Watch this video to see what I'm referring to:

    Alternator wiring issues

    Check your grounds. I had a similar issue on my work truck, was the main battery ground to the block. The end was corroded and broke off when I moved it. Try a temporary ground from the (-) on the battery to the alternator body.

    How old is your lower shift cable?

    Water when pulling stern drive

    Yes the upper bushing is also a seal. The lower one is just a bushing, no seal. Is your upper bushing the larger upgraded design like in your link? or do you have the original smaller bushing? You would also want to get a new shift arm/lever, they can be a bugger to try to remove without...

    No gas to carb

    Disconnect the fuel line from the carb inlet. Have someone hold it in a pail and crank over the engine about 10 seconds, see if an gas comes out; if yes, then you have a carb issue, if no gas, the problem is upstream. Like Scott mentioned, could be a problem with the anti-siphon valve which is...

    Mercruiser 470 Only Showing 10 volts

    Here's the wiring diagram to add in a belt driven alt. Power it off the purple wire to the choke, not the wire between the choke and (+) terminal on the coil. That wire is a resistance wire and you won't get full 12 volts to power the alternator. You're pretty lucky on the exchanger, I had two...

    Boat turns over but will not start

    Ethanol gas does not like to sit for 3 years. The needle valve in the carb is probably welded closed with corrosion. I'd drain the tank right out and pull the carb off, get a gasket kit for it and open it up, clean out the bowl and passageways. Remove the gas line at the carb inlet and check the...

    Identifying 1976 Engine-is it a 302 or a 351?

    That flame arrestor looks like it needs a good cleaning too.
