[Lucio344]

i need help to identify the engine in my 1978 starcraft chieftain is says mercruiser on the engine but cant find any other info on it and cant find any thing but the vin on the sterndrive it is 2000470.This is my first restore project i need to redo the transom and floor in the boat thank you for any help

Ayuh,.... Welcome Aboard,.... That, is the infamous 470 Merc motor,....

The biggest mistake Merc ever made,...

 

[Lucio344]

What is wrong with these motors?
And any idea what the stern drive is ?

 

[Bt Doctur]

the cast iron ford head on an aluminum block ,way different expansion values when overheated even slightly
drive is a very early one with most parts no longer available
Would not spend any money trying to restore this one. If you love the boats design that much, install a newer motor and housing from a donor boat.

Is that drive original on a '78?

 

[Bt Doctur]

its not an MC1 drive, guessing early 60``s by the serial number MerCruiser 0 (Sterndrive) 1965-1966

:welcome: to iboats Lucio,

Nice big Chief you have there. :thumb:

I would think about finding a donor boat for your restoration project. There's a good supply of older glass donor boats out there with newer Alpha motors and drives. Take a look at my Chief restoration and you'll see it's very doable and you'll end up with a boat that's better than new. :happy:

so i put new plugs in the motor (that has not ran in 3 years ) put some fuel in the carb ad it started right up for couple seconds i have found that the fuel pump is not working . would i be better to relapse it with the same kind or put a inline electric pump in ?

also when it starts i get water in the coming out my drain on the back of the boat (from inside) where should i start looking ?

thank you for all your help

did you put the drain back in the heat exchanger? The engine should have coolant/ anti freeze in it. If so I'm betting on the drain plug.

There are two in the heat exchanger, the AFT end one is sea water one... that's the one that gets removed to winterize the engine.

Thank you the end cap was undone any othere things i should look at? that would have been done this is my first stern drive

did you check the inline fuel filter on the inlet to the carb for restriction? sitting that long then needle in carb could be stuck closed not letting fuel into it.

If the fuel bowl is empty..... you should be able to disconnect the fuel line, and blow into the carb with your mouth using a piece of hose, if it wont take air, the needle is still seated/stuck. would have to disassemble and clean the carb...

Here is a link to series of videos by Alpheus on here, who made them on rebuilding a carb, in case you haven't done it before:

You could also disconnect the fuel line off the carb and stick it into a container... crank the engine over and see if gas comes out the line and into the container..

the card fuel filer was plunged thank you for the help
