1994 5.8L EFI, wiring and OMC or Volvo drive questions

[johnmogs]

I've surfed enough here to know most guys will tell me to run from the OMC/Ford, but I think i've got a sweet enough deal to consider it further, pending answers to my below questions. Thank you in advance!

1994 Four Winns Candia 214
Engine Model #58FACPCMDM, SN: T01273156
Outdrive Model # 3868052, SN:T0786812
Transom Model # 3868030, SN T00348607

I got the engine model number off the intake cover, but couldn't find in Google search, so not sure I have the correct Engine Model number.

Boat has bad seats and gel coat needs a good rub. Engine is not running due to a wire harness meltdown (between the boat and the plug going into the motor harness), looks like either friction and/or the exhaust manifold melted the wires and once naked they shorted. I can repair the wires as there is a lot of slack, but not sure it will run. It may have overheated as the outdrive is very dirty, might be full of mud. So if it doesn't run, these questions will help me figure out the next options:


First Question: is this a OMC or Volvo outdrive, the tag said OMC Cobra, but I found this model # in another post and comments said it's a Volvo. I couldn't find the Volvo decoder website so I'm asking here, if you know, please also let me know what Volvo's marketing name is (like MerC's Alpha, bravo). Otherwise I'll assume it's a OMC Cobra and will be hard to find parts. I don't know Volvo's well, more familiar with MerCruisers, so any links to Volvo outdrive evolution would be nice.

Next Question: Wire Harness between boat controls and motor harness, I assume it's low voltage and protected by fuses, so it shouldn't have killed anything like the motor's ECM. Is this a safe assumption, or should I look for other fried parts on the motor? any easy checks?

Third Topic: If the engine does not run, I'd like to replace with a GM 5.7L, is it possible to install a turn key GM Merc 5.7L engine without changing the outdrive? I would buy the turn key with all the manifolds, etc. just not sure if I need a hub adapter and if the exhaust will fit, or if I should just get the full Merc 5.7L Alpha/Bravo system from another boat. If I do is the transome hole pattern the same for my oudrive and the Mercruiser Alpha and Bravo systems?

Thanks very much for any help you can offer, I realize this might turn into a big winter project so I'm not planning to pay much for the boat, but do like the deckboat for space and the 5.7 for pulling kids.

Re: 1994 5.8L EFI, wiring and OMC or Volvo drive questions

It's most likely a Volvo SX drive. Those were the OMC/Volvo joint venture years. Mine is a 95. It said OMC Cobra on the drive, but it's actaully an SX. As a matter of fact I bought a later model Volvo Duoprop and just bolted it on. The concern would be whether your engine/drive package was a 92 or 93. Just because the boat is a 94 doesn't mean the power package was. I do know that in 94/95 Four Winns was putting the joint venture stuff in. That means the engine would an OMC, but the drive and bolt-on's were all Volvo.

The biggest issue I would worry about is whether the short toasted the computer. You can't get them anymore and if you can find one used they are BIIIIG $$. Then again you could just put a new intake manifold and carb on it.

But listen, trust me on this. Walk away. I own a Ford setup in a Four Winns from this vintage. Find another boat. Expertise and parts are really hard to come by as time goes on. I am pretty well versed on this setup and am presently in the middle of a long block build. I can tell you all kinds of parts that can be cross refernced to aftermarket stuff, and it STILL kicks my ***. I will be looking to unload mine in the very near future - I've had it for 6 years. It's as reliable a setup as any when operating properly, but when there is a problem it's painful to deal with.

Exhaust alone for this beast is going to run you almost a grand.

As for the conversion to a GM you are going to need to move the engine mounts and get a GM exhaust Y. None of the bolt on-on's will transfer, including the flywheel cover and coupler. The Volvo drive (if that's what you have) is bullet proof so you are ahead there.

Proabaly not the post you were looking for, but if I can save someone else the pain....

Will a Merc 5.7L flywheel and coupler mate to the Volvo drive, or do I need a Volvo 5.7L, or adapter from the Merc flywheel to the Volvo drive?

If I buy this boat I will plan to replace the 5.8L with 5.7 fully dressed with the y-pipe, engine mounts, etc.
If the 5.8 runs - I got lucky and should sell it running ASAP.

The boat as it sits is not worth much, as seats and a motor swap cost more than the boat would sell for if running and in good appearance, so if I'm up for the project I'll not pay much for the boat.

Any other info on Volvo model numbers labeled as OMC Cobra drives, to answer that question would be appreciated.

Thanks,
John

That's definitely the Volvo joint venture drive.

That's definitely the Volvo joint venture drive.

But does that make it an "SX" or SX equivalent?

if I should just get the full Merc 5.7L Alpha/Bravo system from another boat. If I do is the transome hole pattern the same for my oudrive and the Mercruiser Alpha and Bravo systems?

If you decide to swap with a Mercruiser Alpha (GENII) or Bravo engine AND drive,

It'll all "fit"........but you'll need to drill 2 additional holes in the transom cut-out to accommodate the 2 additional studs in the GENII/Bravo transom mount. You'll also need to relocate the side engine mounts slightly.

I would only get the boat knowing that I would need to pull everything. If the 5.8L engine runs, you can probably sell it and the drive if it's any good. (as-is no returns!!!)

If the engine doesn't run, you'll probably need to part it out or remove all the EFI stuff and put a carb and dist on it. There's no parts for either the Spitfire ignition or the EFI system. (and if you find them they'll be more than what you should pay for the entire boat!!!)


Good luck!!

John,


You had the model number slightly wrong. It's probably 58FACPMDM You can view the parts layout at http://epc.brp.com and just about any other place that sells old OMC parts.

Yes...at least for the drive.
