A friend just purchased a boat with a non running 470 and spare motor unknown if it runs yet also a 470. I will be tapped to help getting this up and running.
My question is what resources have any of you found ( web sites mainly) for parts. IE: manifolds, internal engine parts anything else.
I have not spent much time working on these for several years so I am sure many parts resources I used have dried up.
Thanks |

I've seen manifolds and other parts on Craig's List and eBay Motors. Google the part needed preceeded by "Merc. 470" and several sites will pop up. |

It's a good strong engine for it's size, but I'd not wish to own one today!
This engine was in production for a limited time. You'd have to ask yourself why?
Note that they are expensive to work on.
Note the issues that these have between the shared area "camshaft oil side" seal and the "coolant circ pump" seal!
Also note charging system issues.
The drive uses a specific over-all gear ratio as well.
None of these issues are un-surmountable, just take note!

I fully understand the motors and the pros and cons......Worked on many of em.......including rebiulding a few.
I do not have the manuals for these in my personal posetion anylonger and would like at least them in .PDF files as there are two, and looking for some additional reasources for parts.
Thanks. |

You near NJ they have dozens of 470's,170's on the side of the road can be had almost free.
The problem is none of them run.
You are aware of the problems because now your running into them.
You understand the voodoo procedure to re-install the head?
You understand the slightest overheat, the head gasket goes, and then maybe the head warps. Aluminum is prone to do that.
Maybe it's the 3" exhaust tube has something to do with that, and if a 4" tube is not present it will continue to do that overheat.
How about the charging system, the 600 dollar fix is another reason the boats are sitting all over Jersy not running?
I'm wondering why merc stopped producing the motor after just a short while?
You like the hull, in my humble opinion, i would yank the motor and exhuast and drop in a v6. Something you can buy parts for. |

........ and I thought that my post was a little gruff!
Chiefalen, A little diplomacy, please!
(fyi... I believe that the cylinder heads are cast iron and the engine blocks aluminum!)

Hey Kghost welcome aboard the S.S. 470! I have pretty good luck on ebay and breezeworks and this website too. There are still lots of parts available if you look around. Of course some aint cheap like exhaust manis. Let me know what you find on the CC water pump seals and parts as I am going to get around to rebuilding mine this winter.
Hey Chief who peed on your cheerios this morning?
$600 charging system fix? You can buy a complete brand new alt kit for half that. The exhaust tube is the same as any other mercruiser, do you mean heat exchanger? There are lots of 4" around. And Mercruiser made the 470 in one label or another for 14 years, that's not a short while, unless you're really really old. Hell 14 years ago I didn't have any gray hair, I could read a book without glasses and I didn't have to get up in the middle of the night to go pee. Now I can't say that so 14 years was a long time ago to me.
I wouldn't disagree with you on replacing the 470 with a 4.3 IF the 470 was completely gone and you had a line on a complete 4.3 in good running shape. But you can buy a rebuilt 470 long block with a warranty for around $2000. It will cost a lot more than that by the time you buy all the accessories for a complete 4.3 drop in. |

oops yep maybe your right Ricardo the block warps.
My age sometimes i forget what i ate for dinner last nite.
Didn't mean to be so gruff, was not my intent to appear so.
But sometimes the truth hurts.
Maybe a donor boat with a good drive and motor with a bad hull, maybe damaged in some way would be alot cheaper if it has a 4.3.
Some people equate the 3.7 merc motor with stringers, seeing as omc went out of buss.
Far from the truth, i never had a problem finding a part yet, and in some way's they never have been cheaper.
Hope it works out for you in any case, i never like to see a person having a mechanical problem. |

Ok here is more, I did not have time today at work for detailed info.
"client".........The guy is a very good mechanic!!, Has his own complete machine shop, Runs a motorcycle repair business (independent)Has a boat and uses it strictly for fishing but it is aluminum and a bit small for offshore, ( massachusetts) and he wanted to get a bigger heavier boat for cheap money.
He purchased a used boat from the coastal area
He did NOT speak to me first he went and bought one. The boat will be a good fishing boat for his needs and is laid out fairly well for that.
The boat has in it a 3.7 (165 hp) alpha one set up. The motor has no real history and he did not ask, the valve cover was loose and he looked and the pushrods are missing. The motor is all there and appears to be original including the original charging system.
He called me today and we spoke and I found out what he had after many well placed questions and i remembered seeing a complete soup to nuts 3.7 (165) for sale locally on craigslist. I looked and it was still there. My "client" called and the motor was still available.
He went and purchased it right then, $400.00
Now this motor is a complete marine engine as if it was unplugged and pulled and put on the garage floor. No parts are missing and it appears to be a fresh water run motor only, NO CORROSION anywhere!! Allready has the one wire altinetor in place!!!
Well I went over after work and we got a battery, 4 spark plugs from the other motor in the boat he just purchased and installed them into this motor, Sanded the points, hooked up some jumpers and the motor cranked, poured some gas down the carb, cranked and got a few pops out the exhaust. By then it was getting dark and F'N cold,(20'F) so we called it quits.
So at this point the motor turns over, has spark, and will fire.
He is going to clean it up a bit and redo some misc stuff that has been undone by someone previous, but all in all it seems ok at this point.
Once he gets some minor stuff done he is going to retry starting it and get it running long enough to see if any issue can be heard or seen on the garage floor. If all is OK at that point he is going to fill with antifreeze and hook up raw water and exhaust tube and see how it will run for a while on the garage floor with all systems activated.
If any issues such as rod raps or piston slap is heard, he will rebiuld the block himself.
That is where the manual comes into play, I know he can buy a new merc manual but If I can download it and print it then one less thing to buy.
There are no secrets at this point of these motors to ME, I been around em for 20 years.......I fully understand there reputation and he now does also as I gave him a ear full!!
Also if worse comes to worse a V8 will be going in the boat in a heart beat if I have anything to say about it!! No issues fabricating a motor mount or anything else that may be needed, as there are a couple of local indy shops who have a few known good running COMPLETE V8, that is everything just bolt it in!
What I am asking for and looking for is for his reference and of course if and when I need it for me also. |

Chiefalen and Puget Sounder..... If you are also in the over 60 crowd....., then we can all relate!
And I don't want to discourage Kghost..... these can be good engines as I mentioned earlier.
I'm actually a Volvo guy, but did work on the M/C's for some years... including this engine.
The only two somewhat complicated and out of the ordinary things on this engine are the factory charing system and that dang front engine cover assembly......... Specifically that silly front design Camshaft/Circ pump cover and seal! What were they thinking with the seal riding directly on the camshaft???? 
Oh well!
Kghost, I don't know if you'll find what you need here, but take a look at this:
Service Manual #1 1963- 1973 All Engines and drives.pdf
See Service Manual #2 1974 to 1977 All Engines and drives.
See Service Manual #3 1978 - 1984 All engines

kghost, ebasicpower.com seems to be a pretty good site for 470 parts. Prices aren't as horrible as alot of other places. Someone on breezeworks 470 talk just posted something about rebuild parts and mentioned a site that he said was cheaper than ebasicpower.com. I looked on the site last night and it stated that some of the stuff they sell is OEM. Best of luck, Tom |

Chief don't you just miss boating season? Nothing like sitting out on the water with beer in hand and all your troubles just float away.......
I just happen to have a great running and well maintained 470 and frankly, knock on wood, I love it. I actually have to find things to work on. Now my previous boat had a volvo penta and that thing was a complete nightmare. I was in the bilge more than I ever got to enjoy driving it. I guess it's all relative. |

Yes miss summer. Every day is a new adventure around my house anyway.
Freekin snowblower motor went. I stuck i different motor on it, more hp but had a different shaft. I had to order some parts for it over the holiday week and they sent a wrong sprocket so i had to order it again.
Someone want a 7 hp " H " techomsa with the 110v electric start i paid 60 bucks for, that only needs a connecting rod, let me know. I may rebuild it anyway, lasted 50 years and i broke a connecting rod say 10 years ago and rebuilt it. |

At least you guys have a boat to jump into!
I'm still wrestling with my own boat (I mean nightmare)lol. PugetSounder, I just spent a pile on my 470 for every possible upgrade item. I even installed valves to drain oil,coolant,and raw water. Installed a high temp. buzzer and light on exaust manifold to try and stop an overheat condition. Also installed 74 amp three wire alternator,8mm high output wires and the Pertronix electronic ignition. Oh my god is there any more to do? Hopefully, not for a long time!lol
I think I can see light at the end of the tunnel or is that just another (boat parts) bill blinding the eyes out of me bloody head? lol Anyways, this winter has been rough and I will be also glad to see summer come again. |

You do know this motor does not take lightly to overheating most likly the head gasket will go.
Want help post a reply. |
