Does anyone have instructions on how to do a tune up on a mercruiser 5.7L fuel injection engine?

[Tim M]

There is not much to "tuning up" the newer engines. There are no longer points, contacts, distributer rotors to deal with. Basically, what you should do anually (or more ofter if you get allot of hours in each year) is change the oil, oil filter, gas filter, plugs. Every few years change the plug wires. If you run stabilizer with every tank of gas, you won't need any injector cleaner. If you don't, once a year run some of mercruisers injector cleaner thru a tank of gas.
Are you experiancing any problems?

Thanks for replying. No problems, just want to do some routine stuff to get ready for the new season.

If your engine has a distributor cap and rotor, check for corrosion inside and in the spark plug wire connectors.

Dont forget to install new zinks in the cooling system............................... oh and how about a new raw water pump impeller, I hate it when i over heat in the spring.
Just my 2 cents worth

Don't forget to check/change the spark plugs and make sure you clean your flame arrestors too.
