please, can somebody tell which type of OMC engine do I have

[coast108]

Hello,

we have bought a Chris Craft 205 BR. year built according to the
papers is 1989. The engine is a OMC 4.3L 6V. We would like to find
a manual for the engine but there are quite a few different types.

The only ID plate we could find is hereto attached which gives
the suggestion that it is not the original engine. (this is our first
boat and we are just starting to learn)

Anyone who can shine some light on this or give us a hint how
we can determine what engine we have?

Hope somebody can advise.

Kind regards,

That tag is nothing from OMC. It is a rebuilder's tracking number from when the engine was rebuilt.

There were four models of the 1989 4.3 V6 OMC Cobra
262AMLMED 1989
262APRMED 1989
432AMLMED 1989
432APRMED 1989

All four are covered in the same 1989 OMC Cobra manual part number 507759, so it matters not which one you have.

Look on ebay or if you want a new manual, one can be ordered from Ken Cook publications.
http://www.outboardbooks.com
507759 SM - 1989; 2.3L, 3.0L, 4.3L, 5.0L, 5.7L, 5.8L, 7.5L; OMC COBRA Service Manual $45.00

Thanks a lot, appreciate the prompt reply.

Gonna order still today.

Only hope that the engine is not from a different year and built in later.

Will know soon enough I guess once I have the manual in house.

If anyone knows how I can identify the engine I would very much
like to hear it.

Best regards,
Ton

Hello,

And here are the pictures.

I think we have been tricked a bit. Boat was sold to us with an OMC engine
4.3L 6V and 205 hp.

I found following number now on the engine GM14095288.

I have googled the number and it seems to be more like an engine from 1986 with
about 175 hp.

Anybody knows if this number indicates perhaps building year as 1988 as the
GM number is ending on 88 or is that too simple.

We need to order some spare parts but need to advise what engine we have.

Pleased to hear,

Brgds,
Ton

Looks like a 4 barrel carb on there which would make it a 200-205hp.

Thank you, that is a relieve.

I need to order some belts. the one that powers the hydraulic system of the powersteering.

Does somebody knows if I can use the GM number (GM14095288) to order parts for the engine?

We took delivery of the boat last 10 days ago and while sailing it the berth, one of the belts broke.

It was a new belt but looking at it it might not have been the right one. It should have been thicker and
it looks like it wore down pretty quick as there is a whole lot of black dust in the engine room now which
was not there before. Hope that with a proper belt the problem should disappear otherwise the only
thing I can think of is that the wheels are not in alignment. Or could there be another problem?

Brgds,
Ton

that won't get you very far. looks like some sort of casting number.

I like to go to shop.evinrude.com - all the factory parts books are online with prices and availability. Look at the 4 model numbers I listed above under 1989 and see which looks like your setup the most. But then you can google the part numbers or cross reference them here at iboats.

I bet one or more of the pulleys are rusty in some spots and sanding down the belt. That really needs to be corrected or you will have to adjust the belts or even have to put a belt on every time you go out, does not take much "sanding" to basically lengthen the inside diameter of a v-belt. All that dust ends up in the flame arrestor also, and it is kind iof rubbery and hard to remove.

Regarding the pic showing the Carb, for me it is hard to see if it is a 4bbl or not. The front half of a 2bbl Holley looks just like that also. Looking at it from the side a 4bbl Holley will have a fuel bowl like that on the back half also. A 2bbl does not have anything on the back half.

Re: please, can somebody tell which type of OMC engine do I have

I looked at the Carb pic again, and I think I see the fuel balancing tube that feeds the back fuel bowl, so I am back on board with it being a 4bbl

Appreciate all the feedback. Have looked at the website but can't make heads or tails out of it. Have found a mobile motor service company who will come by next Tuesday and hopefully he can tell us what engine we have. Maybe we should have done that before we bought the boat but we were not the only contender and it became a "must have". A boys thing I guess...

Will have a look at the pulleys and see if I can solve that. Idea is we will become experts ourselves but still a long way to go....

Have a good weekend all!

why do you care exactly? insurance?
I mean it's a 4.3 with an OMC Cobra. what else do you need to know?

Go to shop.evinrude.com, click parts, change the dropdown (where it says "Evinrude") to "Stern Drive", select 1989 and then one of the four V6's... 10 seconds it takes

I don't get why you need to know what cam bearings or balance shafts are in the engine? nothing relevant to maintaining it in knowing if the block is a 86 or 88
All the filters have a part number on them and all the 4.3 Cobras take the same ones pretty much- just order off the old filters. Belts have a number too, generally.

Looks just like my 88 except mine has a Rochester Quadrajet 4bbl carb.
if you want I can look up the OE parts #s for the belts.

It would be great if you could check something for me.

Mechanic came by today and he could not find the exact type either. He is now
going to check the type by checking the type of oilfilters etc on the block
with what is stated for the different types.

He had some V-Belts with him and the ones that fitted where the following:

Alternator : 6229MC Gates
Hydraulic pump : 6227MC Gates

Could you check whether this coinsides with your manual? Would like to
order some spares just to be sure.

Thanks

Thanks, maybe I am making it myself too difficult but from what it seems is that the previous owner has
been a bit too creative. Just want to make sure with replacing stuff that it are the good parts. The V-belts on the
engine where not the ones which should be on it for sure. One broke after two hours sailing. when i bought the same
belt it didn't fit at all. when measuring it I think that the belt was not running over the pulley for the cooling water. Not a biggy I guess as that pulley is also moved by the other belt but it is not as it should. If something is designed a certain way I prefer it to work that way.

And, moreover..... it is turning into an obsessive hobby Want to get it right.
