    Unidentified wire

    yes I would think your oil pressure alarm switch is bad. You can check it for continuity. It should have continuity to a good engine ground when engine is off and open when running and you have oil pressure When these go off its too late anyways you should watch your oil pressure and temp...

    What engine in new boat

    I suspect it may come down to what marine carb you can get. I know for a long time the 1409 was out of stock. I think they had a of road needle and seat for 4x4 use. I had a 1406 on my GTO and a 1409 on my Mercruiser both work great. In a boat I like having the float bowl with no gaskets...

    What engine in new boat

    That's what I thought. Years ago I thought michigan motorz and marine power were both using 600 cfm on their 5.7 partial engine packages, but I saw Merc uses a 750 on their reman 5.7 engines... Either way the OP has a Automotive carb

    What engine in new boat

    That is not a marine edlebrock carb. it is an automotive. the marine does not have the three vacuum ports on front ...also doesnt have an overflow nipple up by airhorn. To the OP get a marine edlebrock 1409 is 600 cfm and will work on a 5.0, if it is a 5.7 might think about the 1410 750 cfm...

    1989 Mercruiser 4.3 LX, Alpha 1 Gen 1 Overheating

    Given your comments on the impeller start there... rule it out as it is the most basic part of the system. Use Oem parts, even “good” aftermarket parts like sierra dont have the lifespan of the oem merc parts. When i had a gen one, i found the sierra impellers lasted half as long as the oem...

    You can get a fuel pump gauge at auto store or amazon very cheap some autoparts stores will loan or rent them. Some replacement fuel pumps are also too high in output pressure. I have seen this myself. You likely need to replace float and needle and seat with good quality parts Mikes carb...
