    Overheating

    Cook You perform your own maintenance but rely on a repair center for "bigger" jobs, correct? Unless you have fair witness of your sea water pump in the drive you're relying on someone else's opinion On this note it's imperative to note this forum is not an avenue for information regarding...

    procedure to manually flush non-running 4.3 engine?

    Ya dude, congrats on the longevity of your old salty. It's neat, but can confirm your situation is unique. Simply because one old cobra 4.3 has survived (with I'm guessing constant observation/repair) does not include the other guessing between 20,000 and 37,000,000 other cobras out there...

    procedure to manually flush non-running 4.3 engine?

    Bummer Not to impugn your method but a quick run on freshwater muffs isn't a bad choice for a discerning sterndrive operator prior to launch With as many people pro and con on this forum considering salt water use I'd say you're either 100% fine or it's time to replace the entire...

    Tow rope to Talon bracket?

    Thank you Your OP seemed as though you may be on the verge of catastrophe. Human life is a treasure many take for granted, especially when considering another they've created. This situation not only confuses me but bothers me at times IMO there is never a good reason to visit your local fire...

    Which generation of 454? 454 is a complete different engine from an sbc btw. A 7.4 is light years ahead of forgiveness towards an operator/owner as an sbc
