Does anyone know if the RZ4 will have the 8.1L

[RID22]

I really want to buy the RZ4, but I'm concerned that Tige might use that 6.0L. I've had that 6.0L, and it always had problems, too endless to list. I keep reading horror stories about that 6.0 on wake world threads, so I know I'm not the only one. Does anyone know if Tige's going to use that 8.1 in that huge RZ4? I've only heard that they're testing it.

i take it you sold your vé

it dosent even say you can get the 8.1 on the rz2 or any of there boats for that matter

[RID22]

Sort of, it's a long story that I can't really get into. However, I've heard through some friends at the factory that Tige may be concidering the 8.1L for the RZ4. I may or may not have also heard it's being tested in one of the proto RZ4 plugs. Which, I think the 8.1L would be an awesome choice. MC's been running that 8.1L for a long time, and I never read horror stories about it. Plus it weighs more, who doesn't want more weight in the back of their boat. Marine Power is also much more familiar with the 8.1L, then the 6.0 that they recently started tinkering with. It should have less problems than the 6.0. From everything I've read it's close to bullet proof. I'm hoping they make the right decision on this.

proto RZ4 plugs

what is that

[Coach]

My guess it that it will be an option. Lee is the expert on this one, but if I remembered right I could opt for the 8.1 with the RZ2 but the cost was $$$$ and not what I wanted as I had a 454 big block in my boat.

[Tanner]

Man you must like burning the gas ;). I've had 2500 lbs my 24V and never had a power problem with the measley 5.7

[wannabewakeboarder]

we couln't afford to run 5.7L my friends 21i has the 5.7L 350 small block triple digits to fill the tank...i think

I usually have 10+ people on my boat, and I put about 40-50 hours a year on my boat in Powell. I surf 70% of the time, wake board 20%, and motor down the channel the other 10%. The 70% surfing keeps my fuel costs low. Honestly, the few times I had bigger guys on my boat wake boarding, I felt like that 6.0L had no pop. "Proto RZ4 plugs" is an extremely lazy way and probably not correct way to say Prototype RZ4 Plugs. The plug is the RZ4 hull. Tige has a couple of prototype boats running tests, with different motor packages. The gas will be expensive on the 8.1, but I also know from experience that the 6.0 is junk. I don't mind paying a bit more to have a reliable motor. I'm looking for reliability, the cost is second for me. I was just wondering if anyone new anything definitive about the 8.1 being an option.

well you can be over charged for my boat it has a 4 cylinder 140hp "Iron Duke" motor 28 years strong rebuilt in 04-05 35K ($35,000):eek: :D :eek:

[RID22]

That's a great deal! It just needs a tower.

im savin up for skylon pod(extented pylon) its $429 i have about $385 care to donate mr.big spender:rolleyes:

[RID22]

I'll donate $10. You need the pylon, it's getting close to boat season.

Did you try a different prop? I know my 5.7 is never really taxed no matter how much we weigh it down. I did have cavitation problems, which is why I went with a 13x11.5.

[RID22]

No, I didn't try a different prop. I asked my dealer the same thing, but he didn't recommend switching due to our altitude. The motors run pretty weak at 6000 ft.

[gman]

how about the new 5.7l with 360hp and high torque?

[wannabewakeboarder]

nuck'n, sent you a pm

[gman]

You can also see if Tige would work with Indmar and use the hammerhead (stroked 5.7l) with 400hp and 420 ft-lbs of torque.

[spharis]

Marine Power also told me they have started working on adding roller rockers and other hop-up parts to the 6.0 Tige is using. I had called for some parts info a while back and got to talking to a tech for a while.

[RID22]

I won't go near that 6.0 again. It doesn't matter what Marine power does to the motor. Marine power had a really hard time getting that motor dialed-in, at my altitude. If they can get a reliable 5.7 that pushes 400+hp, I would consider that motor. Motors and 6000ft don't mix well. Maybe I'll get a 5.7, and throw a whipple charger on it. That would be Nuck'n Futs!

[spharis]

Only problem with the blower would be feeding it air down in the hull.

[FIC]

The only problem that the 6.0l has in the marine enviroment that we have come across is fuel purcullation. Every marine manufacturer has had this same problem , and they all have addresed it with a different fix. This problem of fuel purcullation causes a multitude of problems , stumble on accelleration, hard start after a short shut down, stalling if you idled for long time say cruiseing through a no wake zone to name a few. We adressed this problem and worked with marine power and can assure you that new 6.0l engines coming out from marine power will be the best you will be able to buy . The reason that master craft and others avoid the 6.0l and jump to the 8.1 is they have not been able to profect there 6.0l. The reason that tige boats perform so well with smaller engines and the others dont is do to a better hull design. The 24ve that pulled the pro am with 2500lbs minimun ballast , multible passengers, and 5.7l pulled riders with ease and at very reasonable fuel consumption. My boat is powered by the marine power 6.0l which is under extreme use , as well as I have sold a high percentage of 6.0l engines and as of yet have had no warrantee issues.
