Topic: 2.5L Rebuild using a commercial 3.0L stroker?

[DodgeMudder]

Good news.
I talked to him last night.  This is the motor we want (2.8L Merc).  The crank will bolt in with no clearance problems.  There are a couple of choices for the rods and pistons.  When I track down my Merc-cruiser engine and start building I'll post every thing I can.
The wife even said I could build the stroker 
Gotta go at work.

Hmmmm I'm really interested in more info on this crank, and a better spec as to what motor year and such it's comming out of to make it easier to find.  This could be a great start at making a monster of a build.

Another friend that I'll be seeing Saturday works as a marine mech.  I plan on having him pull the engine specs from their computer or copy the pages that I need from the manual.  He doesn't know it yet but he is going to help me find my Merc motor.  I'll post them as soon as I can get them.  I'm still curious about the 3.0L indust motor that started this.  I don't know how hard this Merc engine is going to be to find.
Later all,

I don't think it'll be too hard to find it, the hard part will finding one without a boat attached to it...

I'm still skeptical, but once you post some numbers and proper comparisons I'll have more confidence in this option!

[Bikerjr1]

If I do find one with a boat, well, that's no problem.  I have a SawsAll, beer cooler,and a big trash bin that will take care of the boat.  I'll probablly have some help too, how many times do you get to cut up a boat. It will be a big trash day.

If it is a fiberglass boat, I recomend you cover yourself as best as possible; fiberglass on your skin itches like hell!

I know exactly how it feels, ever retrofitted houses for surround sound and satellite? running wires through insulation-filled attics really kills...

I know that a stroker has been brought up before  and is always shot down but hell why not do one. If I were to do it, the goal displacement would be 3.0l and build it to be turbocharged. Im just wondering if there is anyone who knows what it would take to do this and what kind of numbers this sucker could put out. Just trying to start a discussion and maybe inspire some people to push the limits on the little motor that can.

The 3.0L Merc is the most common boat engine on earth.  If you are looking for one to screw around with, you can get them cheap since they are pretty much un-rebuildable (Cannot be bored out).  My last couple boats have had 3.0L in them, good motor but they are all carburated.

[oldjeep]

One other thing I should mention is that there are basically no performance mods available for the 3.0L even though it has been in use for 20 plus years.  The reason is that the motor tends to self destruct if you get much over the stock 135 HP rating.

Well I was checking out a later FSM today, just looking at specs for the VM Motori 2.5TD, while it has a longer stroke than our 2.5's, I think the crank is just too short. Not that it matters too much, because it's europe-only...

But anyways, I was surprised to learn the VM is actually an OHV, two valves per cylinder, driver-side drought engine. Roller lifters unlike our engines, but it's still pretty interesting. I wish the crank and connecting rods were interchangeable, they pretty much have to be forged because of the high CR, I'm still looking into it but I doubt I'll find anything...

I'd like to know what progress bikerjr1 has had too, if possible?

another old thread brought back to life/  nice to see people still looking for more options/  if we get a solid answer on fitment maybe my monster will come out and get that last bit of push to cap off my engine build

[Bikerjr1]

It will probably be another week or so before I can get the specs.  My friend has to download them at work and burn them then I have to catch him when I'm in town.  Hopefully it will have some useful info.  Still no luck finding a 2.8L Merc motor to tear apart.  The search goes on....

 I'm out of town untill late may, In Luxembourg at the moment. Hopefully someone can source info while i am gone. if not I will continue on the quest when I return. I know we could get cranks made to our spec, and it would be cheaper if several of us was serious about the project. I know people at crower cams they have the ability to custom make any crank shaft, but one off's are costly.

Extremely intresting stuff here!

Read the whole thread from start to here and gotta know did anyone ever figure out if the crank from
the 2.8l merc work??

i remember going thru this also and didn't find a definite answer - dwtaylor mentioned in another thread that he knows somebody that was running a 3.0L stroker (if i remember correctly but not sure) but i don't know if that was the pre-chrysler motor (whatever was used in Pontiac & such) or the one we all have - maybe he can clarify that and if he's got more info i'd be really interested to hear.
