You have that much reversion that it pulled water from that close to the end the exhaust? That doesn't seem right.

Yep.... Even putting your hand next to the collector at idle you can feel it sucking in..

So if im lucky, ill get the rod bearings ordered tomorrow (if thats all it needs) they will be here wednesday. And maybe just maybe i can get out to the lake saturday or sunday

So what is you plan on exhaust? Add mufflers?

To be honest I have no idea what the actual laws are on jet boat exhaust. No one has ever batted an eye around here on dry exhaust boats I know of but one of my buddies said he was busted for not having a baffle on his Dana?

Also, in the photo with the drain pan, was you engine lifted up or does it sit that tall in the boat?

Gonna run the headers dry. If i get a ticket i get a ticket. Later on ill add water injection to the primaries like the bassets and run them on a valve. Manually controlled.

But for now run them completely dry.

No the engine is lifted up on the hoist. I have about 1/2 inch clearance without lifting it

Jet boat exhaust... or ANY exhaust on a boat- Pre 1993 (I think) must conform to SAE J-1970, and 1994 and later, SAE J 2005... this goes by the year of the engine, not year of the boat. Yes, This is on the Colorado River, at Bullhead/Laughlin

I've been checked 3 times in the last 7 to 8 years, twice by Nevada Wildlife, Once by Bullhead P.D., and had the Ranger @ Davis Camp walk to the transom with a night stick.(Before he let us in.) They only looked for baffles, (Mine are visible from the rear) or the 'night stick' test, night stick hits a baffle, your good to go.

A typical Big Block Chevy/Ford/Olds, with logs and snails, is at or beyond the limit, But they never bat an eye...
And there ares signs at Bullhead Community park launch, Rotary park launch, Riverside Casino launch, Davis Camp, Lazy Harry's, Etc.
If it looks like you comply, You'll probably be all right, Drive like an Idiot, they will slam you with the book.

Steve- Water injected headers have a weep hole that allows the water to leak out, (rather than into the cyl. head ) with your 'steam lines' hooked up, weep holes (and a valve) MIGHT save you.

Yes... I know ill be illegal.... Ill worry about it when i get a ticket. But i just want this thing to get wet and move under its own power.

My only problem with the "steam lines" Is they are necessary for the LS engine, without them, the rear cylinders can run hotter than the rest... Heres a pic of an aftermarket solution for EFI installations

So, a valve might have saved me if i only opened it at higher RPM. But i dont think i can just turn these off and have them be okay when at low rpm/idle. And since a boat spends a decent amount of time at idle (long no wake zones) i think ill be better off tee'ing from the cooling line to the header inhjection when i do that. And just running the steam vent through the transom un-obstructed. So it free flows as it needs to

« **Reply #156 on:** June 01, 2015, 08:13:44 PM »

I'd just run the steam lines to a hole in the transom. You don't really need flow from them, just a way for air to escape. I'm actually surprised you got that much water out of 1/4 inch line.

Does your MSD have a RPM switch built in? Maybe hook a parker valve to it a RPM switch to turn the water on at 1500 rpm or what ever RPM reversion is no longer an issue?

Yeah I think it does. Idk for sure

I'm going to run it straight through and worry about water injection later on.

If I get hassled at Elsinore for noise I think I'm going to mount a set of dynomax bullets on it and say eff you I have mufflers

You know, since you are running those dry you may want to weld in some O2 bungs. Putting a wideband on that to tune sure would make it easier...

I do plan on doing that later on. Just a Wideband is not in the budget right now

Yesterday my new Rod bearings came in so i went ahead and replaced them. My dad took the oil pan to his work to clean it out real good and put it in the jet wash. But he got side tracked and forgot to bring it home.

So we got the rod bearings replaced. Mains re installed and everything torqued back down and cleaned out.

tonight we will set the pan back on and set the engine back in the boat.

The plan was to get the engine back in last night, Fired up and do another oil change.. but that obviously didnt happen.

So i moved onto the list of things i have left to do. Which wasnt much.

I moved to Bilge pump, because where it was water would be about 1/4 inch up the flywheel when the bilge would stop sucking water. So i moved and epoxied it lower in the boat.

Put the packing rings in the pump.

Added some more silicone to the transom adapter. When i was testing the bilge pump i noticed i had a small leak from the corner of the Transom adapter. SO i went ahead and added another coat of silicone to that as well as the bowl/transom adapter seal

Scrubbed the seats down used bleach/water mix and magic erasers. Major difference. Also followed up with some of the meguiars vinyl seat care stuff. They are so much softer

Wired up my Step retard to a switch. Im not 100 percent sure where i want to mount it, and if i want to drill a hole in the dash or not. So i ziptied it to the steering rack for right now. Its out of the way and you cant see it

when this is turned on the MSD will drop 10 degrees of timing.

Rebuilt the 1310 drive line i picked up from a member here (88carrera i think). Put brand new Moog u joints in it, wire wheeled it and painted it gloss black

installed my el cheapo walmart fir extinguisher

And finally got the gas pedal installed and mounted.

At this point all i think i have left is
PTO (ordered should be here today or tomorrow)
Drill the rails for the rear motor mounts
Eventually fab an alternator mount
Washers for ride plate spacers
Gate valve
Beer!

Anything else you guys suggest i check/do before this thing gets wet? I think ive crossed all the bases but i could be missing something.

If everything goes right, and as planned. She will be on the water this weekend

« **Reply #161 on:** June 03, 2015, 09:30:24 AM »

You know, I would put a few hours on it before changing oil again. When it gets up to temp it will boil the moisture in the engine out. Seems like a lot of $$$ in oil.

I'd add one of these while it's out. I think most late model GM drain plugs are 12M x 1.75

I am thinking really hard about putting a LS4 in my Omega as a cheap replacement for the stupid 396. I can get those engines with low miles for $400-$500 since they have the small 60 degree pattern on them. I bet I'd break even after selling all the BBC stuff off. LS Swap EVERYTHING!

I have one of those hoses on the bahner. But i really dont see a simple way of running it in this thing. Plus to change the filter ill have to pull the motor anyway. It takes abotu 10 minutes to get it up high enough to change everything.

I was thinking to run it at home for about an hour or so and get the oil hot. Do this once or twice. Then change the oil. but i might leave it in there and jsut change it after the first lake trip

Yea, they are stupid cheap. All Aluminum with LS6 heads.

Positives:
Cheap
Balancer is super short for more room.
They usually only have 100K on them.
Pan has tons of baffles and is low profile
All Aluminum
Cheap

Negatives:
I would have to make a rear plate for the 60 degree pattern
Have to figure out a starter (no provision on block and flexplate is small)
Only 303hp stock? Seems weak for a 5.3 with LS6 heads. A better cam and free slowing intake/exhaust + vavle springs + higher rpms would probably bring this up a little.
Might have to swap the timing chain cover to work with a MSD 6LS (It's 180 out on the LS4)

I had an 08 GXP for awhile. It ran very well. I had a full exhaust on the car (STUPID LOUD) but before warranty was up i got my dads work to replace the trans. While it was apart we my dad and i changed the gear ratio and also built the trans to shift nicer (shift kit, blocked accumulators etc) Because of the gear ratio change i had to have it dyno tuned.

ended up at 284hp and 320 ftlbs at the tires (if i remember right i know 320 is right, hp might have been 283, 285 somewhere there). Car was a lot of fun. Front tires didnt last very long at all. I will say.. The car handled like it was on Rails. It had a "G meter" in it from the factory. Going up to Oak Glen i pulled .91g's in the corners once. Crazy. I wish i still had the car

Yes he does, I used to be a brake and front end tech for GM as well. But now i sit at a desk all day.

Hes the Trans/Heavy Line/Foreman for a local dealer here.

No i did not get the core there, i bought it from someone on Performanceboats

« **Reply #168 on:** June 03, 2015, 11:28:46 AM »

The GM dealer has a bunch but I have been unsuccessful getting them to sell.

It's probably good they don't. I'd LS swap everything including my forklift.

thats odd... his work has 1 core right now. But it is very rare that they have an LS engine core or are replacing one.

Lots of Gen 1 blocks though

Got the oil pan on and the engine buttoned back up. Also got it set in the boat.

This little gem came in (1 day from glenwood marine) Are they gold colored because they are fuckin expensive for a fancy spacer?

got the engine lined up where it goes, with the driveshaft and pto attached. I left about 1/4 inch of play in the driveshaft before it bottoms out.

Also got the steam lines ran for good this time. I drilled/tapped the transom adapter and added a 1/4" npt nipple to it on the inside of the boat. Later on ill convert this to AN line but this will do fine for right now

So now, the boat is ready to go. The drive line isnt hooked up currently (so i can run it on the trailer) but it is there and just needs its 4 bolts.
All thats left is to
run the PCV line
Get a filter for the other valve cover
Grease the wheel bearings
Put all the tires on the trailer
ziptie some of the hoses/wires out of the way. Just to make sure they are secured
Find a way to hold the scoop down to the carb. I have some ideas ill try them tonight
Clean/vacuum the boat
Wash my truck

And i think thats it. Shooting to hit Elsinore early Saturday morning

Well shes together and ready (i think) to hit Elsinore tomorrow. Pulled it to work with me to day so i can go to the gf's and just leave from there in the morning.

Just for shits and giggles i pulled out the trusty Radioshack decible meter i bought when the radio shack i went to was going out of business, it was 4 dollars i think.

Im @ 91db at idle (about 20 feet from the boat) and 118 @ 2500rpm... fuckers loud lol

Shawn (sevans01) works about a half mile from my house. He texted me, that thing is loud i can hear it over here...
