Does anybody know what engine I have?

So the oil pan has a similarity to both pans from the link. The drain plug in on the bottom and the dipstick comes in from the side near the bottome. It is actually the dipstick mount that is leaking, not the drainplug as I had described previously. I have sent an email to skidm to see what they have to offer. I appreciate the help.

There's nothing special about the oil pan in the boat. What I would recommend is finding someone with an oil pan from a gt40 PCM, then getting the stamping number off of it. That stamping number will be a ford number. Order a new one like that, or simply call up Summit racing or Jegs and get a new one.

As long as clearance between the hull is enough, I' can't see why just about any 351W pan will work. This is not a marine specific part. The only thing you wouldn't want is a double humps style as there is no cross member to have to get around on a boat. That would make oil changes a little extra work unless you use an extractor.

I don't recall the configuration of the 351 HO sump, but I am pretty sure it's just like this on a gt40.

edit.. DIM has this one for 400... still a lot of $$ for an oil pan, but it is a little different than the standard automotive ones.

I guess that's half off from your original quote.

Found what I believe is the parts list that PCM will not send to me.

I have not gone into depth to verify the pure accuracy however it seems to distinguish a gt-40 350 vs 351 motor being GM vs Ford which I did not know. The schematic of the Pan looks like mine as well. I will hopefully confirm in the next few days.

My 2009 price sheet points all of those item "11" to now be R005004A at $324.08

I'm sure white lake can make you a better deal....at least use the PN discount.

I will check out White Lake for sure today. I don't think the 2009 and the 1997 have the same block though so they would have a different pan.

I got an email reply from skidim.com - which has been the most helpfull vendor response so far.

The original equipment Ford pans are no longer manufactured. PCM sells us a modified automotive pan that has been totally re-worked to fit the Ford 351 Oil Sump. It is Item # 1708 on our website and cost $409.02. We are planning a bulk e-mail Spring promotion on the 18th for 10% off.

The PCM part # for the original pan is R005018 if you can find one on someone's shelf.

The part number from PCM is in the attached PDF on this thread for those who care.

FWIW, CC stopped using the Ford engines in 2003 because they were no longer being produced by Ford in production vehicles and quantities were low I guess. They moved onto the GM 350 engines "Excalibur" and 6.0L models. My guess would be you need to be looking for a rear sump oil pan from say an F-150. Either 302 or 351 engine model should be okay as the only real difference is the deck height of the block. I own a 1993 F-150 Lightning and know for a fact it's oil pan is designed that way. Weather or not it will be an exact match to your PCM pan I cannot know though. As long as the pan does not have clearance problems with the hull the only other thing you should really be concerned with is the clearance between the oil pickup tube and the bottom of the oil pan. I think the clearance should be around 1/4"-3/8", but don't quote me on that. It sounds lie your homework is paying off and you know the part number you need now, just finding the part is the issue now. Good luck with it.

On another note, if you can't seem to find the correct pan there is always the possibility of repairing the old pan if it can be done. It's just a stamped steel piece that I'm sure could have the bad pieces cut out and new steel welded in place. Not the ideal option, but another plan of attack.

First of all, there is no such thing as a GM GT-40 It is a Ford trademark designation, I believe.

You have had a few good suggestions on what to do to fix the pan. I find it hard to believe it is unrepairable.
You also might be able to put a Ford truck oil pan on the engine, but I would think the chances of that is rather slim. A different pan will require a different oil pickup to match the pan.

I really have zero business being on this thread. I couldn't do any of the work you are talking about.

There are tons of what seem to be great ideas and being Airtool and Daniel C are posting and I trust those guys comments, might a put a couple comments out there.

1. personally, I'd pay the extra $$ to get the replacement pan, do it right once.
2. We don't know the hours on the boat, but being in saltwater what else is the boat going to need. while the motor is out, what else should be done. think about the transmission also.
3. Might you have to replace the motor someday? Again we don't know the hours or overall condition.
4. While the motor is up how do the manifolds look. those bolts suck to get out while the motor is in, plus easier to heat them if you need too. also metal shavings in boat carpet SUCK.

I hope it isn't time for a new create motor

Sounds like you are going to a lot of trouble getting the motor out. I'd think you wouldn't want to do it multiple times, plus if the 125 LBS girlfriend is going to help she might only want to do it once or it just might be you and the boat on the lake.


As for the websites. Please support WLM first if you can because they donate to the site. However I buy from Skidim and you will find a lot knowledge there.

The PRICE SHEET is from 2009...NOT THE ENGINE !!!

I have given you the current part number (R005004A) that the 2009 price sheet says replaces R005018.

I now suggest you get some help with this project.

Yes, GT 40 is a ford trademark. There is no GM gt 40, just like there will be no ford SS.

Ford stopped production of 351w motors in 96, maybe some were still available in 97 F250's on the old chassis.

PCM bought as many 351s as they could and marinized them. They were used up through 2002. Then the GM's were 100% phased in, and the windsor fords were out of new marine use.

Also, a 302 takes a different pan than a 351w. The heads may fit from a 302 to a 351W (stud size is different but easy to get around), but deck height , intake and other differences were present.

If the dip stick is the only thing leaking, you should be able to fix that. taking the pan off and having it inspected might save you a lot of cash.

Alright so I finally am all set. I am going asimple route to begin, and keep my fingers crossed a bit.

I spoke with WhiteLakes who were by far the most helpful of any vendor I spoke with. David DeAndrade is the GM there and was able to fill in the blanks a bit. Coorrect Craft also finnaly did respond with the same data White Lakes told me and sadly PCM never once answered my question; they only said call my local distributor. I reached out to them 3 times

The original old Pan number is: R005018, which has now been discontinued. Everyone was correct with their understanding tht a car pan could fit however the clearance would not work from any standard car or truck model. Ford made a pan specific for this motor for PCM which we have. This at least is what I am told. Today however the pan is created by PCM which is the new model mentioned on this thread, part # R005004A. It appears this new pan has some cross over ability with the newer motors as well. Both CC and White Lakes confirmed the part number.

While I am perfectly capable of pulling the motor I just don't want to if I can avoid it. Speaking with the White Lakes the plan is to buy the replacement oil dipstick parts and drain plug kit, which I can return should the pan break while trying to remove the old parts. If the pan breaks my options are to then buy a new pan anyway or weld either way the motor has to be pulled. Also I will need to find my toold because I will have thrown them all over the **** place....

White Lakes was priced about 40% less for these parts than my local distributor and over 50% less for the replacement pan should it get to that point.

As far as the spots of rust go that are on the pan currently, I am going to go with Por15. I painted my trailer with this stuff and for those who have never used it, it is **** near bullet proof paint/rust inhibitor. The paint will seal the pan in the state that it is right now and the rust will no longer grown.

The rust appears to be strictly surface rust. I tested the rust by whacking the pan on certain areas with a hammer and picking at the rust. No sheets or flakes came off at all. I took some mild sandpaper rubbed the pan a little and found the normal metal beneith with almost no effort as well, so I feel really confident in the integrity of the pan body, so long as taking the parts mentioned do not tear off.

I give myself about a 90% chance at success, and hope my bolt/nut snapping carma does not come into play once again.

I appreciate everyones help and thoughts.

Let's hope it all goes as planned. That POR15 is good stuff, but don't get it on anything you don't want it on.

1997 nautique is different

The 97 ski nautique had the closest fitting motor to hull.....If we all remember the 1997 was the 1st BRAND NEW HULL design on the ski nautique since 1990, so trying to fit a non GT40 PCM pan in that specific year may be near impossible....for those of you that never owned a 1997 ski nautique, you wouldnt know this... but it was the only year that the motor/pan didn't come standard with the black quick drain hose in it because there is "NO ROOM IN THE INN" to have the drain hose fit between the pan and the hull....the 1997 is a royal pain in the *ss to just get at the oil filter because of such close tolerances....CC fixed this situation in 1998 and changed the mounting and even changed the hull back to a standard looking bottom since the motor was lifted up for more clearance...and in 1998 and newer, CC went back to putting in the black drain hose standard....

None of this will now matter as "MR BOBOLINA" is not going to try and replace the pan anyways...

The support that eveyone offers up on this site is absolutey amazing!
