    New rebuilt motor value-gctid813364

    Can any one give me the ballpark figure on the cost or value of a mercruiser 383 stroker V8 with 85 hours on it?

    It's going to depend largely on the build level of the engine. Is it complete with new manifolds, belts hoses everything to drop in like a new factory build or a long block. A stroker isn't much more expensive to build than any other 350. The shop clearances the block for the 400 crank, from there the parts are nearly the same replacement cos if it's a basic rebuild. The difference is really when specialty parts are installed. I have a stroker in my '72 Nova that has a list of competition parts a mile long and the price to me reflected that.

    IMO the stroker is a great improvement over a 350, but don't get caught in the game that there is significantly more value. Look at what the rebuild companies are asking price wise and add for and additional NEW parts, then discount that about 25%. As a walking in point I think that's where I'd start. Question is, why is that motor being sold with only 85 hours on it?

      I guess I'm more skeptical than pcpete. I would say 50% of new is value.

      If I buy a new one then I try to sell it unused I would expect to lose 25% just because I'm not the original factory seller.

      Now its used it loses even more value. You have no idea what has happened to it. Was it broke in properly ? Was it abused? What is oil pressure and compression? Has it ever been under water or ingested water?. For all that I say 50%. Now the other question is 50% of what?. If it was a home build sell then price goes down if it was a local machine shop price might be stable but if its a factory merc or a michigan motorz engine then i say 50% or lower depending on the build.

      Under no circumstances do you want a 383 with short piston skirts. Good for the race track very bad for a boat so you need to know what's in it. Short skirts won't get you more than a few 100 hours if even that on the engine..

        The reasoning behind this is I bought my 87 wellcraft antigua 265 off a guy who was retiring last september. He didn't want to sell it but his wife had talked him into it. The motor is the original motor so just factory stock but it is completely rebuilt. I took the boat as a bit of a project boat but it runs excellently. The dashboard, gauges, switches and read outs were bought brand new when the motor was redone almost 2 years ago. The guy I bought it off of said he couldn't get the digital panel to read the hours on it. I was tinkering with it and found 2 plugs not connected under the dash panel. I reconnected them and everything ran like a top. The hours were reading as 84.9 so I connected water to it and started it up and just watched. It changed to 85.0. I paid $3,800 for the boat so I was stoked when I learned the hours were that low. I was just wondering the value of the motor in it. It looks almost brand new. It was kind of the feeling of buying an old corvette off a guy who left it covered in a barn for 20 years.

              DittoDave! Great advise being given to you......... please take heed!

              NOW..... I don't know exactly why you asked the question since you appear to be pleased with the performance of this engine!

              Please note that IF this is a Mercruiser 6.3L (aka 383 cu in engine) it will have been a "Re-Manufactured" 4.030" bore GM engine.

              If this is a Mercruiser 6.2L (aka 377 cu in engine) it will have been a new standard 4.000" bore GM engine.

              In either event, it will incorporate the dreaded GM Full Dished pistons.


              Use Caution re; your Progressive and Total Ignition advance!

              Here is a thread regarding the 6.3L SBC (aka 383 cu in) from back in April of this year.

                I love this boat. I just got it registered yesterday. It will be awesome when we can get it out on the water for a family vacation. My fianc├® loves it. I redid the interior and put a bench seat and table in place of the booth seating. My 13 yr old son says it looks a lot newer than an 87 and likes it. My 8 yr old daughter said she likes it but doesn't want to stay on it overnight yet. Its still sitting on the trailer. Not sure how she will be on the water if she wont stay on it on land.

                From what I have been told about motors, a remanufactured motor like one that new can cost $4,000 to $7,000. It was a huge surprise. I just wondered if it was true.

                Chief, I don't think I have any papers on the motor but I am going to go through all that again today.

                  The 383 cu in (aka 6.3L) SBC is a remanufacturered engine, possibly from GM or others, and may be tagged as a Mercruiser Engine.

                  I doubt that any of us would need to pay near $7k for the 383 version.

                  And once again, please be very conservative regarding your ignition advance on this 383 that you have!

                  Also, this boat is apparently a 1987. Unless I missed it, you have not mentioned what stern drive it is equippped with!

                    Ah, now your question makes more sense. The advise about being gentle is gold. Kinda like the guy with a car that everybody just knows will s#%t and git, he doesn't need to prove anything. Take the kids through a boating safety course, it's not just about learning safety, it's about confidence and knowing what to do in an emergency. Practice with your crew the simple things like timing the boat up and releasing lines. Once they have it down a bit, do it with the engine running so they understand the louder voice is required both directions to be heard, it's not anger, but there will be stress in your voice.

                    You talk about the boat being on a trailer, go to your local ramp on a Sunday afternoon for some great entertainment and lessons. There will be those that have zero problems, then there will be those who are disorganized, tired, and very possibly had a bit more recreational beverages or whatever and really demonstrate what can go wrong. You'll find you may want to have a paper checklist, at least in the beginning, so that everything is completed. Nothing like getting the boat off the trailer and to the dock and then realizing that the plug isn't in.

                    Here's to wishing you and yours a great time.

                      Without hijacking the thread, I have the 6.2 Horizon MPI, and reading through this thread makes me think I should simply throw it over board though it has been good so far. What should I do so as not to encounter any bad things due to the dished pistons? We cruise at 3400 or so RPMS and are adults.

                        Make sure your timing advance is dead set at the OEM specifications and no further, In other words, this engine can produce better performance with a "quench style piston" being fitted and timing could be bumped ahead a touch but with the "one size fits all piston" that it's likely been fitted with it could be prone to some detonation if timing isn't spot on. As all sbs's, It's a great engine as is, ibut it could be sooooo much better.

                            To answer the question. If installed and running right it makes the boat book value. Maybe by being new it adds a bit over book but not much. Book value assumes that every single thing works. If it doesn't then you start deduction process.

                              On the stern drive, I am not sure which one it has. I am very new to boating. It looks very similar to the Alpha one on my bayliner 1850 but I don't think that is it.
