LT-1 lets see some pics!

I am working on my LT-1 to replace these braided hoses with stock ones. I am also eliminating the t-fitting for the shower (that does not work anyway)
I'd like to see the front of the engine if you guys have any pics.
Any slightly modified LT-1's out there? Would love to see pics of those as well.

My '96 is in pieces (rebuilding water pump and replacing water pump drive seal) so I can't take any pics. Mine looks a little different with the alternator mounted down low.

Where is your shower tee? Have you thought about fixing the shower?

It doesn't look like your steam pipe on the heads has been moved to the front. Mine had not been moved either, they took the thermostat out to keep it cool. Fixing that is what led me to the oil leak and rebuilding the water pump.

I just recently read about the kit needed to move the steam pipe to the front....will look into that next. The engine runs cold right now so I have to check both t-stats to make sure they are there and working. I'm going with new t-stats anyway plus moving the steam pipe....not taking any chances here.

I may fix the shower too, it may just need a new y-fitting (it's located under the port side of the engine but it leaks water) The pump runs but not sure if it's pumping.

Did you get the rebuild kit off of Ebay? How is the rebuild going? I need to pull mine off and redo it also as it leaks.

what is this steam pipe that you guys are talking about?

I got the kit from H20pumpman1 on eBay. I have the old pump apart with the impeller off and bearings punched out. You just take the cover off and punch the shaft out. I need to paint some areas on the pump and put it back together. I might relocate my heater hose to the pump as well. I will have to drill and tap a hole to do that.

The same guy on eBay sells rebuilt Corvette pumps for not much more than the rebuild kit. The pump for the '92 Corvette appears the same as the pump on my '96 Indmar. The pump for the '93 - 96 vette has a heater hose location on the front. I am kind of wishing I had gone that route and moved my heater hose. You would need to add an inline valve to be able to shut it off.

The steam crossover pipe is located on the back of the heads on automotive applications. Since our boats have the engines mounted at an angle, the steam pipe needs to be on the front. The heads are the same on each end, so there are plugs where the pipe installs.

If you have any questions, let me know.

quick question ... understand getting it stock, but the braided hoses are much more durable than stock

Here is a pic I use to help identify hoses with customers. Sorry, I don't have the original without the numbers, this is a high output LT-1 from one of the Anniversary boats which is why it's blue.

Corey - Could you identify the hoses in this picture for us? It would be helpful for us newbies...

I will try to help. The hoses with direction of flow:
1) Transmission cooler to raw water pump
2) Raw water pump to back side (behind thermostat) of water mixer
3) Front side of water mixer to port side exhaust manifold
4) Circulating water pump to back side of water mixer
5) Back side of water mixer to circulating water pump thermostat housing
6) Same as #3, but starboard manifold (this hose is barely seen in the photo due to the Perfect Pass module)

There is a small (approx 3/8") hole in the water mixer/thermostat housing that bypasses the thermostat allowing water to the manifolds at all times.
