    RE: Issues with Mercruiser 5.0 LX 4 Barrel Carb

    i am assuming you did do a valve leak down test whilst the heads were off ?. how did the cylinders look ? glazed or lost x scratching . over heat can cause glazing and lower compression ."however' to drop compression that low and after a gasket change still having low comp would indicate...

    Pertronix question.

    i did see that post , yes i agree it is "showing as" running slightly lean, retarded timing can appear to show lean or rich symptoms on plugs and valve heads. OP posted that after running for a bit it picks up , this is because the cylinder temp are probably getting to a point of being...

    Pertronix question.

    I'm no xspurt . but from experience it sounds to me like the timing is retarded by a few degrees . forget the timing light > advance the timing by small increments till you get a slight ping under acceleration from a full stop , once you get the pinging , retard the dizzy back to the last...

    trailer surge

    ? why do you need to be towing that amount of weight @65 + mph , your " car" is not built to do that even although it will pull the weight it is not meant to be doing it @65 + on the highway. that's a heavy load for a car so its only natural to have problems as you drive faster.

    Can I replace my 1994 Mercruiser 5.0 2BBL (305) with a 1998 5.7 2BBL (350) ?

    the 5.0 is a good motor , a couple of things i like about them is: #1, they are robust , in stock form they don't make enough power to hurt themselves #2 , i have seen a few making big power and almost bullet proof with only bolt on performance bits and a properly dialled camshaft. a 5.0 can...

    Can I replace my 1994 Mercruiser 5.0 2BBL (305) with a 1998 5.7 2BBL (350) ?

    you should be fine , i am with jimmbo on the gear ratio change as a prop change is sufficient to change the RPM up the top and load when under acceleration , iv hotted up many outboards and never yet have i changed a gearbox ratio to get the performance figures i have aimed for. just a prop...

    Dry Firing Outboard

    some motors have different poppet valves, thermostats and water flow , for example , my 4 stroke Yamaha takes 10 seconds or more to start pissing water with a new pump . you should be going by the strength of the flow once water flows rather than how long it takes to initially start to pee..

    RE: Issues with Mercruiser 5.0 LX 4 Barrel Carb

    you need to figure out why the engine got that hot and stayed hot long enough to smoke the motor component's so badly..? was the foam wrapped around the front of the lower gearbox blocking the water intake holes. i am surprised there is not water in the oil from that overheat on a SB chev, so...
