CHECK THE VID PLEASE.
There is no easy way that I can see to just hook the hose up to a 5 gallon bucket. Everything is SO tough to get too. I can't find the line in the back either. I even pulled the floor board up that comes up. Yes, the Tower looks to be homeade... I think it's unique, plus once I get my 4 tower speakers on with the LED lights and windows tinted I think it will be pretty slick. I finally found a mechanic in Louisville NE that is going to take a stab.

Follow that hose off the raw water pump you were pointing to. It should go over to the port side of the bilge and run back. It should go through a trans cooler at some point (metal tube 8"-12" or so long, has two small lines to trans out the side), then after the trans cooler through some more hose into a through hull fitting near or next to the trans. You may have to poke your head down to see and then work by feel in that area if there is no easily removable part of the floor after the doghouse.
Anyhow, just follow that hose. You may be able to disconnect the hose from the through hull and have enough slack to get it into a bucket (or fitting on side/bottom of bucket) sitting on the floor next to the engine/trans. If it won't reach just disconenct the hose from the through hull side of the trans cooler and buy a piece of hose the same size (1" or 1.25", likely) that is long enough to get you to the bucket. Or remove hose from raw water pump side of trans cooler and it may be long enough. You can run the engine on hose/out of water without the trans cooler getting water, it's only needed when in gear and trans is making heat.
FWIW that raw water pump doesn't look new? Could be and was painted but just scuffed up on install. Hard to tell in video. New circulating pump (on engine) is good. I assume either new backing plate or if old was reused it was clean with no holes rusted through? Regardless, you'll learn to work blind when needed. Anything that mechanic did nis suspect, just gotta check and see waht's good/bad/unknown and go from there. If you were in my neck of the woods I'd gladly lend a hand, big block Ford power in an old Supra is sweet! If my 454 ever dies or needs a rebuild the Saltare is getting a 460.

I am very late to this party and didn't read all of the posts so not sure if you were able to ascertain if the water pump is installed correctly. When I first bought my 84 Rider someone had installed the water pump backwards...very easy to do...looks the same either way. I discovered it by looking over the edge of the boat and saw bubbles coming up from underneath because the water pump was pumping the hot air out. Easy way to tell if the pump is backwards if you see bubbles coming up on the side of the boat. Not sure if your intake on the bottom is on the port or starboard side. Mine was on the port side. reinstalled the pump the right way and never had another over heating problem.

In your video there is a person standing behind the engine, you need to lift up the floor section they are standing on. You will find the through hull fitting the hose is connected to. Disconnect the hose and add another section of hose with a double barb fitting. This will give you all the length you will need.
A 5 gallon bucket is way to small, if things are working properly a garden hose cannot keep up with the demands of the raw water pump. I use a base from a 25 gallon shop vac and even that gets sucked dry very quickly when my engine is cold and at high idle.

Chautaquasun, I made sure the raw water pump was on correct. Wulphie, I pulled that back panel up in the past and don't remember seeing the through hull fitting there. Will check when I get my boat back.
UPDATE.... I finally found a mechanic that owns a Street Rod/Boat Repair shop that was willing to repair/look at my old boat. You won't believe this, or I guess most you may considering many said it has to be just a water flow issue, but he said the boat was pulling through water, but after a couple hours ($$$$) of trying to find out why it was overheating he found that whoever put in this engine used a cheap hose for the main intake, and you are supposed to use copper lined hoses to avoid kinks/damage. Apparently the hose UNDER THE ENGINE, (which I would have never probably found myself) was completely kinked/flatted and gets even worse when you accelerate. He is POSITIVE this is the issue along with another kink/old hose. I won't believe it till I see it, and plan on picking it up and taking it out midweek so I'll keep you updated. If this is truly the fix, I will RAISE HELL with the previous mechanic who removed heads, grinded them down, replaced impellar, thermostat, etc etc etc! New mechanic said he'll literally give me the hose and you can clearly see why there was a problem. He did say it took several hours of labor to really track down that hose under the engine and at an idle it did seem to suck in enough water. WE SHALL SEE SOON IF THIS IS THE FIX. WISH ME LUCK!

That will do it for sure.
You need hose like this. . . http://www.westmarine.com/buy/shield...11_333_001_505

Wow, that's very interesting. Totally plausible. You should have the wire-reinforced hoses for the intake, yeah. I guess no one here thought to even ask about that, myself included! It does seem that an inspection of all the hoses should have been on the radar for anyone looking at the issue previously. But then, even this guy looked at it for several hours before thinking of that.
I hope you're in the clear now and you can move on to enjoying the boat!

Totally makes sense. If the hose was not the right type or just old and deteriorated, it cna fail like that. On the exhaust side I've heard of them collapsing internally to restrict flow while appearing normal externally. Either way, raw water pump sucking through collapsed hose would definitely cause your issues. Now you could have had issues with warped heads and such too, resultant from previous overheating. If so that was fixing the symptoms of overheating, not the cause. Glad you've finally got it though! Wish mine had a 460!

Please post a pic of the hose

Took it out. Funny story.... didn't over heat. Got to middle of Lake. LITERALLY water was pouring from doghouse!!! Water so cold idk if we would've made it. I was ready to go down withy Supra. Fortunately the engine never died and I got it to the boat lift. With all the water in the boat the 6000lb lift wouldn't pull it up. After bilging and a shop vac was able to get boat lifted up. Today we searched and dropped it back in to find the hole. Once I got down real low I found a whole completely underneath the engine a little smaller than a golf ball. I then found a a huge plug that screws in ironically in the cup holder. The first mechanic must have pulled that out when winterizing and never put it back. UNREAL. I would've never known there was a second plug. I got it in and all the water is out. No more leaks and it's running very cold if anything. Need to put new thermostat in. I'll be sure to post some sweet pics of the boat soon. Hopefully I'll be issue free for a while. Thanks for all the responses and help.
