    Compression Test Readings

    at least someone was honest about what was wrong with it. Just make sure the deck and head are flat before you go back in. With a machinist straight edge. Reason being as mentioned above looks like someone was in there doing head gaskets already… prob overheated the **** out of it replaced...

    Mercruiser 5.0 vortec / 4bbl upgrade

    im with bondo im always amazed what decent used running engines sell for. another option get a 96 and up 5.7 from a truck out of a wrecking yard . Change core plugs to brass or stainless, marine head gaskets, freshen up rings and bearings if needed. strip your 305 accessories put them on 5.7 you...

    Merc cruiser 5 0 backfire

    mine will seem like a popping for sure when i hit it. If you don’t know what it is or not experienced could be confused with a back fire easily. Big difference between a lean condition is the boat will run perfectly until 4900 + depending on tach accuracy

    if you have an issue with the carb or contaminated fuel you need to take those items apart clean them and reassemble. Running seafoam through a carb wont clean it out, just like topping off bad fuel with new only makes more bad fuel.. Do some diagnosis and see what's going on.

    Carb Issues At Small Elevation Change?

    Sounds like some of the passages in the carb are plugged probably the transition circuit, if you mash the throttle and that helps seems like accelerator pump is working. As Bondo said fuel filter is a good annual maintenance item - check what comes out of it. With mositure and sitting typical...

    Merc cruiser 5 0 backfire

    I suspect its probably a lean sneeze. if you haven't done much to it would start with a compression test to verify good mechanical conditin. certainly verify timing and empty contents if fuel filter into container and see if there is anything other than clean gas. What do the spark plugs look...

    Carb Issues At Small Elevation Change?

    Normally that shouldn’t make a difference With such a minimal altitude diff. Would suspect you have a fuel delivery to carb or carb rebuild issue. if you slowly advance the throttle does the problem occur or only if yiu stab the gas. what is the maintenace history of boat? Would start with fuel...

    Removal of broken head bolt

    Is part of it sticking out once you remove the head? On things like this and exhaust manifold bolts if you can get at a stub of it and apply some penetrating oil and heat you may be able to get it out. If there is enough of a stub I put a pipe wrench on the bolt after heating it. If broken...
