Phyton GURUs???

I'm putting a rebuilt (mostly GM parts) 502 into my 99 super air in the fall. Leading up to that I need to get my ducks in a row since spare time isn't something I have a ton of.

New Motor will be in Long Block Form from Oil Pan to Valve Covers. (no exhuast or intake gaskets included).

Old motor is still in the boat and complete. It was running (poorly) until it poked a rod through the side.

Removal/Re-install... Anybody have any tips for getting this giant sucker out of there. I'm sure it can be done once it's striped down and free from the trans/v-drive but it would be nice to put it back in as complete as possible so I'm re-attaching more things in the well lit garage on a stand as opposed to upside down in the back of the boat.. I've done 3x direct drive motors now but this will be the first v-drive.

My Shopping List:
-Intake and Exhaust Gaskets (I'm assuming I shouldn't re-use the latter.)
-Plugs
-Fuel Filter: Is the FCC the same between the Python and the Gt-40? I've actually got a filter and o-ring new in the package from a previous boat.
- Oil and Filter: I'm going to talk with my motor builder but: anything you guys would recomend? Time before break-in oil change?
- Trans Fluid: Figured I would change it while I'm in there.

Anything else I should service or swap on the motor itself while it's out?

In the boat itself I plan to:
-Service or Replace the throttle and steering cable
-Clean the Bildge
-Remove the Hard Ballast Tanks and get the plumbing ready for bags.
-Service the Rudder, Prop Shaft Seals, ETC.
-It's got a few gallons of fuel in it that I will probably pump out.

Anything else in the hull/bildge I should attend to while I'm at it.

The impeller is on my list just forgot to post.

Cooling and exhaust hoses are a great idea... I did all of them and fuel lines on my pro air and I think I’ve still got some of all of the above.... Just didn’t really think about it because my pro air was such a mess it had to have all of them.

Battery cables and bilge/blower are good to.

Glad to hear the rotella, I run it in my duramax and a few other things.

Take it with a grain of salt but from some preliminary research the 502 is very similar to a mercruiser 502. Somebody on PN had info that the ECM was used in various applications and could actually be tuned as well.

Bueno, glad I can use the filter I've got.

Thanks Zach that would be rad if you've still got it.

Glad you've moved on to greener pastures but wish you were still around for the motor laundry list and some seadeck once it's a runner.

hope all is good.

Is this one ok? or do you still want Zach to look

Looks to be 6ci short.

New long block the same configuration as the original? It’d have to be for the stock tune to carry over. Curious how you spec’d the heads and cam.

I theoretically have the original parts list used for the original python 502 build.

It’s just a word document I think direct from Mark Snider.

Show off

The Everglades are apparently full of them.

Probably a short pump, so the less common of the 2 typical auto types. Not sure if all marinizers used the same pump that Pcm did.

Appears most did... Only a few part numbers in my search most of which fit 454-502 from several different marinizers.

Zach you ever find the OG parts list?

If it’s the same list you sent me a while back it’s just the Pcm rebranded peripherals... plugs, filters, etc. No engine internals or anything like that.

So what’s the status on this project man? I’ll be in Grapevine February 10-12 for a work conference. Be willling to lend a hand if you need some help??

Externals are really what I’m after anyway. I’ve found a few things I cannot wanted to replace but most things aren’t listed for a python or 8.2..
