Used PCM GT-40 5.8 L for Sale

No light bulbs next time!


What chances would you be taking if you did have to have work done on it? Find a decent shop that won't try to bolt on 8 cylinder heads or 8 piston heads! Really, b2 said it and I'll confirm that the risers go first because they are out in the open. If you don't have popped freeze plugs, I'd say the engine is ok.

I've suggested before....for block/head leaks.....to cap off the raw water intake and rig a way to pressure test the system with a radiator pump.

That lowers the chance of damage to bearings , etc. during a test run.

You can borrow the pump from AZone.

I appreciate the recommendation. I will definitely investigate getting a second opinion on the GT. But if I have to get a new engine, the choice is a PCM Excalibur 343 or the PCM ZR409. I will post a vote to see what I should go for. Keep in mind that I'd be paying like $3k more for 66 more HP. I rarely drive boat at full throttle so to me it does not make sense. Never had any problems getting out of the water with my GT40, so don't see need to go for larger engine. But I am a man, and have the thought that bigger HP is better. What are the thoughts here?

$1,500 including shipping doesn't sound too bad.

Why are you selling the whole motor? Why not replace what's bad and put it back together? Replacing reverse rotation motors is sometimes more difficult than you think. The stuff that's broken will not be rotation specific, any good motor shop should be able to make the repairs for you for less than $2k.

There was a new GT40 on e-bay a few months ago, reverse rotation for a correct craft and all. It didn't sell in either listing I saw, maybe it did sell on a later listing. I vaguely recall the price was $4,500 plus shipping.

Thought after 90' that CC's with a 1:23 trans were standard rotation engines, with the trans running opposite the engine for a RH prop?

Yup, youve got it CQ. GT40 is a conventional (LH) rotation engine.

I disagree that the argument that the block is "probably good". Id say that its likely to be bad. Its just as likely that the heads, intake or exhaust manifolds are junk as well. No way to tell by inspection. The "freeze plugs" arent actually designed to protect the block or heads from cracking- theyre just casting plugs.

[Mikeski]

OK,

That make sense, I forgot that the PCM tranny's on the GT40 switched Correct Craft's to LH rotation. Even more reason not to replace it.

The other thing Grant did not mention is that CAR's GT40 was rebuilt and installed in LukeDuke's 2001.

In my opinion... you are setting yourself up for a big disappointment changing from the GT40 to a Chevy. Back when my father was running the west coast promo team as a big Small Block Chevy fan, he opted for the Chevy "upgrade" a couple times. We were consistently disappointed with the Chevy's performance compared to the Ford. Regardless of peak HP rating, I think the GT40 makes a bit more torque when needed most. If you were a barefooter or ski flyer looking for a top speed machine, the Chevy 409 would be the motor for you, but I suggest you are more interested in the sub 3,500 power and that's where the GT40 really shines.

how would i hook up the heater on my 05 210.

If you are referring to a engine compartment heater, it just plugs in.

Mike, youre still missing it- the GT40 is a conventional automotive rotation engine, just like most marine engines that are sold today. Correct Craft used to install reverse rotation (RH) engines which allowed the boats to use a RH prop when paired to a 1:1 tranny. Now that the 1.23 transmission reverses the direction of rotation (which it has since it was introduced in 1989), Correct Craft can mate a regular old LH engine to it and still swing the RH prop like they want. Theres nothing special about the rotation of the engine anymore- its all in the tranny (which I dont think the original poster is considering replacing).

I do agree with you about the 351w being torquier than the Chevies. With the right prop, though, the Chevies shine. They have a lot more lungs from 3500 RPM on up- especially that 409. With a few bodies in back, they had the CCF 196/409 hitting 57mph on the GPS this past weekend!

I'm going with the PCM Excalibur 343.

I found an engine online at www.skidim.com for about $3500 less than the dealer was quoting. It is good to know that someone else bought from here. They don't make the GT40's anymore, but the Excalibur is selling for $7,980 now.

How much will the tranny be for the Chevy? I don't think that the GT-40 bolts up to the chevy block, but I have been mistaken before.

[Flipside]

The 2001 Super Air will have a PCM 1:1 trans connected to the Walters v-drive. Skidim.com said they would have PCM put the correct damper plate on the engine so it will bolt right up. Skidim.com also said the 2001 does not require the special $700 "grayhill box" like the 2002 - 06 to make the gauges work.

TRJ,

I was typing too fast, I meant conventional rotation... I just had too many OLD boats running backwards LOL.

You are missing the point I am trying to make to Flipside. You cite a 196 with a 409 and barefooting, exactly the combo I was referring to as being the right application for the Chevy. Our wakeboarding tugs beg for the torque of the Ford GT40.

Not sure how much weight Flipside runs in his SAN? I know that I am very disappointed with the performance of my Chevy Excal. Dissapointed to the point of installing $1k worth of hi-flow aluminum exhaust manifolds in an attempt to get more power out of it. The manifolds did help but my Chevy is still anemic below 2,500 RPMs. With full stock ballast and the passenger load at the capacity limit my 211 will not pull a wakeboarder out of the water, will not even get on plane running a 13.5x16 prop. I do have a 14.5x14.25 prop available for those times but I still like to slalom and I hate running up towards the 5k range pulling at slalom speeds, it also shoots spray up into my face in a headwind, so I prefer the 13.5 x 16 for all around use.

Best of luck, don't set your expectations too high.

[Flipside]

Holy #@$% Mikeski, you've got me scared! Does anyone else have this same experience with the PCM Excalibur? I would only run the stock ballast and maybe 4-5 people on the boat.

[Laptom]

Flipside, let a rebuilder (not the dealer) examine the GT40!!
These are great engines and by no means worse or less then the newer 330 or 343 Excaliburs... I owned all and really didn't noticed any difference between the engine regarding speed or pull. We only run stock ballast and mostly 4-6 people in the boat.
The GT40 was perfect, the biggest difference I noticed was that the GT40 was much more fuel efficient!!! We could run up to 9 hours of wakeboarding on the 145ltr of fuel while the Excalibur would only do about 7.5hours on 145ltr.

Mike, I hear you- Ive got a mix of new ('90, '03) and old ('71, '78) CC's at the dock, so I have to be familiar with both set ups!

Im not missing the point you were trying to make- and I agree with you for the most part. The Fords have better power down low and the Chevies sing better up high- but the size of their respective power bands are similar, so I would think they could be set up to perform similarly by choosing the correct prop. I do realize that we're talking apples and oranges with the 196 vs. the wake boats, but I also think that the way you use the boat is the exception rather than the rule. I have heard of very few wakeboarders using their boats to barefoot! Im sure youve thought of this already, but you might want to check out the 6.0L if it ever comes time for you to upgrade. It pulls hard right up to (and sometimes past) 5700 RPM... it doesnt feel any stronger out of the hole than the 330excal to me, but I would think you could prop it down a bit to gain some low end performance without giving up all your high end.

Flipside,

The 343 is plenty of motor. It pushes my buddies 220 with 6 riders and 2500lbs or so of ballast just fine.
