RESALE VALUE
GO MERC.
GO MERC.
Oh yea those bores are waaaaay out of round! Then they use those low tension ring packages as wellCarb'd HP 500
GM HO 8.1 block
GM Dimple rods
GM forged crank
GM bearings
GM 088 325cc heads
SRP forged Pistons
Crane cam
Crane roller rockers
Crane springs
Dart intake
Holley 800cfm carb
The exhaust and peripherals are all Merc though [emoji13]
Oh, and badly out of round cylinder bores (Merc didn't bother using torque plates) [emoji57]
4v heads allow bigger flow numbers with tamer camshaft profiles and smaller duration numbers. 2 smaller intake valves can flow more than one huge one, especialy at low lift. 4 valves can make better use of the combustion chamber space available. Notice you dont hear those 1350's idling high or loping at all.
But it is way more expensive, and GM has very efficient 2v head designs in the LS and now LT motors that make it unneccesary to do 4v production motors on their V8's
Those Merc QC4V motors are bad ass though for sure....when cost is no object the 4v OHC BBC delivers the goods
No option for build it yourself?
My first choice would be stock factory merc or ilmor power, followed by custom power from a proven marine engine builder such as Pfaff, Teague, or Larry Peto

Really?Any reputable builder would.
Does builder back up work 100%? Or does customer get to pay again?
Any reputable builder would.
Not true.
Sometimes they start to believe that they can do no wrong. NOTHING can possibly be "their fault" because they are legend...it says so right on the Internet.
Now if you are the one in a hundred that has a problem with the builder, and clearly demonstrate what and why that problem is, what do you think your chances of getting it rectified are?
Zero, that is what your chances are.
99 people will line up and rip you apart for daring to cast dispersion on their hero. Never again would I ever pay someone for something that I can do myself with actual attention and care, because when YOU are the one that gets fucked you have no recourse.
Factory, or a REAL custom builder like Teague.
Written warranty and an actual, legible, real dyno sheet.
Sorry to hear about your experience.
Personally, I've Never understood the "get on the Internet and bitch about it" mindset. That almost never goes well.
I have a customer right now that is so made at me it's unreal. And honestly, I don't blame him! He has had more than his fair share of problems.
But there is no way in God's green earth I'm gonna let him stay that way. I'm gonna pay for the tow, and pick up his car, and see what is wrong with it tomorrow.
He says it cranks but won't start. Fuel or ignition, right? It's no way the engine build, but I still have to do whatever will make him happy. I will not let him go away mad.
To think you have no recourse is nuts. The consumer has Tons of ammo! Small claims, BAR or even a letter from a real lawyer is all you need to get the attention you need. Don't give up if you Know you are right!
All the chrome is back on it. I guess it looks ok. [emoji6]You are a good man Joe. You scare me sometimes with the direction you want to go with my GTO. Remember, It is MY GTO!!!!!!
Love ya man.

Merc. has the 520,540 & 565 pkgs. Then the 600/700. Then they jump all the way to the 1100,1350,1650 pkgs. I wonder why they don't currently have something in the 800HP-1000HP range? For that reason, I've always liked the TCM825 & TCM985/1025 pkgs.:thumbup:
Merc all the way. I don't buy into the "for the money you would spend on a Merc motor, you can build some VERY nice one off power" bullshit
No way in hell a custom motor will last as long as a Merc motor under the same conditions.:thumbup:

From the used / consignment sales side of the equation, it's much harder to sell a custom motor / wrenched boat than a stock MFG boat ... just my .02
LOL!!!
Lot's of If's there. How about what would YOU do??
Sorry. I don't have time to read Every thread on this site. Hallett Dave would kick my ass if I did! [emoji12]I believe CT made his choice in another thread. There is a lot of great info on this site if you look around. [emoji14]
Let's not let Grads muddy the waters. [emoji6]
Atta boy Grads. You done good.I voice my opinion and I get accused of muddying the waters, everyone else voices their opinion and they get a pat on the back?:grumble:

And you feel this way why exactly?Don't feel too bad grads.. When it comes right down to it, you are actually right on this one.. Lol.

If you were looking to re-power or even buy new power your boat project, would you prefer dealing with a custom engine builder, or a crate type engine builder, and why?
Just curious what the feeling is out there.
Custom all the way, or do it yourself. I don't buy into the "Mercruiser is the greatest thing since sliced bread" bullshit
For the money would spend on a Merc racing motor, you can build some VERY nice one off power.
put then you get passed by some guy wifes house boat with the bimini up....see ya...... Zoooooom!!!!!
What special parts or construction does Merc put into their moors, that no one else on earth is able to do?
Marketing Budget
I'd go with the guy you trust to do the job and get it done right the first time. I would prefer reliability over excessive power. Strangely...I'm in the market to have this done!
There are a few really good builders out there, there are a lot of decent builders and there are a small handful of top tier guys. Me personally if I am going for stock power I would go with Mercury. Anything non stock would be one guy and one guy only as he has earned his reputation over the years. Brummett is the only guy that has built my dad's engines and now mine. We have waited over a year in the past to have him do things and would do it again. This is not to take away from anyone else out there it's just my .02
Yes. Carson does a great job. I remember you and I skiing behind your dads all aluminum motor when we were kids[emoji106] good stuff.
That was a fun boat!
well, I am biased. My family and I have had several boats. Several of the boats have had high performance engines. Carson, Teague and the other big name builders have always been in the spotlight as I was growing up in that generation. In fact, we owned boats with those engines. Watching from a distance, my dad and I saw Alexi at Boostpower Marine spend endless hours on Lake Arrowhead with boats and at the time lap tops, hand held things and whatever he was doing. We saw him run around in circles with his dads and others boats and fine tune them before injection was really an option for a consumer (hour after hour).It was like the lake was his dyno! At the time we never would use him as he was just a kid in our eyes. Alexi started early and is now just over 40 years old with a long experience of EFI, engine design and actually drives just about every boat made for magazines and private consulting jobs. I am sure he knows what works etc at this point. I am sure the other guys have experience and talent, but Alexi gets it done and efficiently. I can't wait a year for a motor or a month for a part. I need it now! He makes it happen and does not cut quality! I have been told that he designs a lot of the software functions of many top tear ECU's that runs the engines. Another important item I want to share is the fact that I have visited with him at every Desert Storm event at his booth. Very few engine builders have all the competitors stop over and actually hang out and chat with him. He is obviously respected and has a great relationship with all the major hitters in the engine world. To me that says a lot! Who does that! I have tried to get him to trash talk a builder and he just says that all builders have their talents and I respect that a bunch! Anyway, I thought I would mention a bit of what Ive seen and experienced. I currently work with him along with my father and have had a flawless experience for several years. Boostpower Marine is my choice!
Interesting and great question! Even though Boostpower is my company and we provide several services, I would like to mention a few things a consumer should consider.
What level of horsepower and service will you need?
For example, if you need a local anybody to work on your boat for service and repair and your horsepower is 550 or less, my first choice would be Mercury! They have a worldwide network of services and their pricing is decent. They are a public company and have great folks their that we work with.
If one were to have a more custom look and internal parts preference and perhaps a bit more power, I would seek a builder who has been in business for a good period of time and provable success stories. I would also consider were they are located and most of all, Can You Get Along with the people/owners. It's really a matter of relationships for the smaller builders.
Several mentioned in this thread build nice products, however what I mentioned about logistics and relations for sure matters.
The other day a guy wanted our BOOSTPOWER 550. We almost never build those smaller hp motors these days. I recommended the Mercury 565 without custom finishes we modify them with for his repower! He kinda looked at me funny but it's a better price value then ours because ours was and had been over engineered. I mentioned if down the road you wanted to make it into a 900 ours is designed that way. Anyway, I sold him a modified New Mercury!
The other key subject one may consider is the type of boat you are working on vs. horsepower and Provider experience.
I mean if you are building a fast V drive boat, you would want to goto a company that has all of the Logistics and Personal relations for one and then decide who has set them up in that type of boat! A in experienced good quality builder may not set up the motor how it really needs to be for a particular application! Keep this in mind.
Another quick example is that a jet boat engine vs. a v drive engine vs. a twin engine boat application are fairly different animals! So, you may consider throwing out the local qualified company to you and pay the piper to send the boat on the road! We see it about every job! They come for a specific need, they also know that we can come to them and will! Others may do this too!
When it comes to ultimate power the choices get small! Of course Mercury makes their new turbo engines which are an engineering marvel[emoji106], but remember, the small handful of big power builders have good solutions and customization abilities as well.
The playing field is definitely getting smaller by the month but the big power players will survive if not for their quality --for their personalized specialty services!
Anyway, sorry to write a book, but thought I would stimulate some good thoughts.
Thanks
