[@johngrams3612]

Hey guys great build. As a Malibu/ Indmar tech since 2006. I worked for one of the largest Malibu dealerships in the nation. You are right to say they have truck cams in them. That’s normal. The actual problem is those fat sacks that you guys removed at the beginning of the video. Aftermarket ballast has been added. Which is very common for a bigger wake. The problem is that many under experienced boat drivers chop the throttle too fast when a rider falls. And in some cases actually put the boat into reverse. While the exhaust does have flaps on the back to hold out water in this event the boat is sitting too deep in the water for them to be 100% efficient. Hence the motor takes on water into the cylinders and hydro locks. I have replaced many of those engines. And no they are not warranty at that point. Glad to see the video. Glad to see someone else complaining about getting that interior out. Keep up the good work

[@iamrichrocker]

why these excellent craftsmen make the big bucks..and why Dave's shop is considered one of the best in the USA

[@johnwhite1893]

Hi Dave, Indmar tech here, factory certified since 2004. If you get more of these in or run into any issues with your rebuild, Diacom from Rinda Technologies is the official scan software for Indmar as well as a couple of other engine manufacturers. It runs on just about any laptop. All you need is the software, the USB cable and CAN bus adapter for the OBD-M plug. Fun fact, Rinda was actually part of the group who came up with the OBD-M standard. With Diacom, you will be able to see all the live data and perform all the tests that dealers can. The only thing that will be locked is the ability to flash calibration files to the ECM, which will be a dealer-only function. Your team did a great job! P.S. Don't be surprised by the oil consumption rate in this engine even after break-in. There's a reason checking your oil level is a required pre-trip step on a boat. You should've seen it when Indmar used the ZZ383 long block for Malibu's Hammerhead 383 package. 2 service bulletins to add oil coolers and change oil viscosity later, and they finally just sent everyone a shorter dipstick😅 and then dropped the model not long after. The 8.1L was the same way. Over a quart per hour was NORMAL per manufacturer.

[@peaj4812]

I've been seriously considering buying a Malibu with the 8.1L. Would you recommend them.

[@johnwhite1893]

@peaj4812 They had their issues, but not enough of them to make me tell people to stay away from them. However, I would advise to have it checked out by an Indmar dealer who will have the ability to see the warranty history, and will also be able to do a scan of the ECM and look for potential issues. You will also be able to verify if the hours on the tach match the hours on the ECM. If either one is changed, they do NOT update each other in those years. Something else to watch out for too, is the sound coming from the bell housing at idle in neutral. If you hear metallic squeaking or something that sounds like pocket change bouncing, then the dampener plate between the engine and transmission is worn. There was an update on those. I've seen the original plates grenade hard enough to go through the bell housing and sever the steering cable. Scary stuff. So scary there's a very good chance it's already been replaced. But you never know. Just something to watch out for. They also went through several calibration updates on 2004 and earlier models trying to smooth out the idle. They would lope like crazy and not because of any kind of wild profile to the cam. It just took a few tries for the engineers to get the air bleed right at idle without sacrificing tip-in. If the one you're looking at is 2005 or later (last year was 2007 if my memory serves me) then it will have electronic throttle and you won't run into that issue. The later the model you can get on the 8.1, the better, preferably 2006 or 2007. Electronic throttle is actually a benefit on these and if anything ever happens to the ECM, you'll have much better luck finding the MEFI-5 or Indmar E-Controls ECM instead of the getting more rare by the day CEFI-3, MEFI-4A, or MEFI-4B. Happy hunting!

[@johnwhite1893]

@peaj4812 I should clarify that the damper (previous post incorrectly said "dampener" because I forgot to referee my inaccurate autocorrect) plate issue is not exclusive to the 8.1L. I've seen hundreds of them fail, even on even base model small blocks. The one we saw grenade was on a Mastercraft with an MCX, which is a 5.7L. Damper plates see a hard life, especially if the owner likes jumping the wakes of other boats. The damper that you saw bolted to the flywheel of the engine Dave's crew rebuilt in this video is one of the updated designs for V-Drive applications that have encapsulated springs. They are much tougher than the original.

[@martech360]

I have the 383 hammerhead in my 2008 and absolutely love it. It definitely likes to sip the oil though. Which viscosity is recommended for it now? I just did an oil change today.

[@johnwhite1893]

@martech360 I have no doubt you love it, the engine itself is a definite performer! Just every engine has its quirks as you experience, the constant load and high RPM of a marine application makes it addicted to its own oil. The last bulletin raised the viscosity to a monograde oil, SAE 40, unless you're consistently seeing over 90*F ambient temperature, then use SAE 50. A longer-term solution is to install another oil cooler, if it hasn't been installed already. If not, you should already see two coolers on that particular engine. One will be inline on the water inlet hose, which runs down the side of the engine next to the oil pan leading up to the raw water pump. This cooler is to cool the engine oil. The other cooler is bolted to the front of the engine and cooled by the water exiting the raw water pump. This cooler is for the transmission. So, to add one for your engine oil, you just need another marine oil/transmission cooler meant for 1.25" ID water hose, and install it in series with your other engine oil cooler. Indmar used to have a kit for it, but I think it's been so long they've discontinued it. Doesn't take much to build your own kit though.

Fiberglass hull the only metal outside of the engine, fuel tanks and jet drive was screws. The 18ft had water jacked exhaust manifold to allow what little space was left around the motor to be used for storage. The 18ft with nothing but a half tank of gas and me driving was crazy fast.

Several different things on a boat engine vs a car/truck engine, biggest is camshaft, next is the Freeze/casting plugs, must be brass or stainless, as the cooling is most likely raw water (lake or ocean water) cooled,and a regular steel plug will rust away in no time

[@cmwhitt18]

Just think there isn't any transmission, so the rpms don't drop during shifts. It's direct drive so you have to build an engine that holds wide open for long periods of time without having oil or cooling issues.

I’ve seen more than a few boat engines with automotive cams do this. Lobe separation is part of it but also duration needs to be taken into account. 110 degrees on less than 224 duration will work anything above and 112 degrees and up.
