The cartridge that is the shaft, bearings and turbine blades and seals is replaceable thus making the turbo as new. The housing itself very rarely cracks and the weak point is the exhaust housing and salt water decay leading to excess rust which when cleaned will changed blade clearance. This can af...

Bruce

it cant be that much more for new

Oh yes it can.

Bruce

What if its raining out and someone is already in the head?

Bruce

Duhhhhh, boy, you 25 miles from a road and 100 miles from a taxicab......

Sounds like a movie I once saw with Burt Reynolds and Ned Beatty.

Goats don't squeal do they?

Bruce

Depending on the make and model of turbo and geographic location, 2k may be correct.

I've seen turbo's dump below 2000 hours. Seals could have been installed wrong or a bearing wore and killed the seal. It does happen.

Check to see what a new turbo goes for and compare the price.

I hate to tell all you fathers of daughters that while you think they are spending the night over at Suzies house, their out doin the sausage dance with the latest hormone crazed boy. I sat down with both my daughters, told them about sex clearly and how boys were crazed lunatics on a hormone rage b...

Bruce

Scot, I would much rather have the hard coat, fiberglass wrapped material. Its not burning hot to the touch but does get very warm. The problem with blankets is its hard to seal the dry temp areas 100%. That leaves the potential for oil in a leak to ignite against a pipe that can get well over 500 d...

I very seldom get an owner who gives me unlimited resources when working on his boat. I break down all the costs when a customer comes in for a repower estimate and they choose how they want to go. In the first picture above the boat I just finished, I had pressure washed the whole hull area to remo...

Bruce

Some have fed the packless seals from both engines so if one engine quits, that dead engine's seal will get fed with water from the running engine. On 31's this is not normaly a problem as no part of the exhaust system is higher than the water over board into the exhaust connection. But some large b...

Bruce

One way to do it would be to open the charger and add another diode to the current two. Depending on the year, there would most likley be an aluminum plate(heat sink) with the anode end of the diode pressed into the plate with the cathode going to a fuse or dc breaker for over load protection and th...

I do have a nice 454 block in the shop.

Having a guage cluster in a tower is not common due to the amount of wires needed and the possible problem with resistance from the wire length which can make gauges read off. I've worked on all the new stuf and havn't seen a diplay fog up yet. They are built and designed like all other electronics ...

Bruce

Unless someones changed it, the metal panel of the 31 can be cleaned up and rechromed or exchanged for an already done panel. If someone's changed it then a few pics would help to identify it. I've been using Isspro gauges for about 6 years now with good results. They have many different designs dep...

Bruce

If its the "Classic 31" it was made by Cabrera Jr. out in Loxahatchee which is shut down now.

It was a short lived project. I think some of the gang rode on John's(one of the investors) at the Ft Lauderdale show one year.

Don't know if the interior dimensions are the same between the two.

Bruce

John, There should be no problem with either the install or the display itself. Depending on the manufacturer, some may be simpler to install than others but in most cases you can get a 4x4 electronic display as an extension to the main display for the tower. This will read both engines and all func...

Had an armada of sailers come into the marina today all wanting slips for a stay over to hit the Bahamas. After a while they started piling back into the office wanting to extend their stays after looking at the weather reports. No deal as slips have already been reserved. After many complaints one ...

Remove the boost pressure sender and connect there.

Bruce

Flat out around 32psi. After that the waste gate opens.

30 psi gauges are fine.

It means no matter how many times you tell your kids not to touch the hot stove, they still do.
All you can do is put a helmet on them and watch them lick the bus windows as they go down the road.

Bruce

Chiles, I bow to your greatness............Thats funny.

Bruce

Hard to tell from those pics but they look like 6V53 rocker covers, could they be the 400hp engines?

Bruce

Timmy, Down here that would be a 600 to 700 job for 2. I quit doing them myself cause it isn't cost effective and there's just nowhere where I can dump massive amounts of muriatic acid without screwing up the environment. It isn't hard, but the key trick is pressure testing the tube bundles after th...

Bruce

Yes if its for one oil cooler and one heat exchanger.

Bruce

Why would you need crank bearings if they have only 800 hours?
You have journal rust?
Did it have a fuel wash out problem at one time?

Bruce

Nice work Randall.
How much blood and skin you loose changing plugs?

Bruce

Just an observation to those who are looking at bigger boats and power. I saw my 15th failure of the 800 gear behind a Cummins 6BTA370 on the port side today. Gear literaly self destructs at around 500 hours. It is in boats that weigh in at 36,000lbs. ZF claims the gear will standup. But my view is ...

Jet Glo is a two part polyester urethane in both a conventional and high solid paint. It is highly resistant to chemical, UV and salt corrosion. Superior to awlgrip and Imron. Great for aluminum with the proper prep and etching primer. A customer had his Beech King Air repainted with it. Very deep h...

Sure.
When it comes out I'll get some shots.

Its fiberglass exhaust hard coat.
The people who build my risers put it on.

Bruce

Russ,
The shop looks hugh inside, but not for long.

Bruce

Randall, Over time heat can affect the starter and solenoid if the solenoid is part of the starter. Same goes for start wire to solenoid. If everything else works then main power to starter ok. First would be to squirt some CX in the ignition switch. Start with something simple. If an automatic it m...

Bruce

Surge tubes are an extension of the exhaust that allow a "surge" of water to accumulate instead of going up the exhaust and drowning out the engine. Instances would be hard backing and the up and down motion of the boat in the water. Do all boats need them? No. It depends on the exhaust design and o...

"Time Machine" is done and delivered to a very happy owner. Some comments on the D4. 1. Was lead to believe they were really quiet. They are not. Typical diesel sound. 2. Mounts have very "flexable" rubber and I found out why. At idle they shake and at 1000 they some what thrash in my opinion. At 11...

Randall,
Most of the really good painters I've met over the years have more than a few dead brain cells.

I remember painting most of those bus interiors with nothing but a paper doctors mask.

I couldn't spell carcinogen back then.

Bruce

Bill,
Are the tachs shorting out right away or do they work for a time?

Were the old tachs two wire and the new tachs three wire?

Bruce

Well first off is the spray equipment. A good hvlp spray gun is about 350.00. You'll need a compressor with a good regulator and air drier filter. Full suit with a really good full face respirator when using those paints. If you have spray experience then okay. If not learning on Imron or awlgrip ca...

Bruce

Mikey, Please don't feel you have to change your exhaust cause of my comments. If you've been told the 5" will work and that's what you want then giddy up. Since you don't want mufflers, are you using surge tubes? Do you have the risers built yet? Reference this thread of pics I posted awhile back w...

Bruce

Now exactly which bar is that snapper hole at?

Bruce

Turbo's are no more difficult than any other piece of machinery if you know how and have the specs to do so. If the cartridge fails(the part that has the shaft and turbine blades) due to a failed bearing it can tear up the housing to where it needs either maching with sleeves or just replaced. BTW a...

Bruce

Mikey, Every pair of Cummins engines I've installed 300hp and over, mufflers or not had to have 6" exhaust or the Cummins rep that certifies my installations would not have given them the go. This goes for the QSB 330hp's that went into a 31 fall of 05. I'm not trying to argue with Tony's recomendat...

Bruce

Thats about $1400.00 to $1600.00 in parts new in box.

Bruce

I know.

Just damn tired of hearing anything about the Pats. Share the wealth.

Bruce

You talking about the wet exhaust elbow or the 90 degree elbow/riser?

Bruce

Mikey,
Whats the HP on those Cummins?
300hp and over are gonna require 6" exhaust.

The marine industry hasn't been known for introducing new technology with a low rate of failure. While the concept of the drive does lend itself to improvements in drive technology and installation of propulsion systems, no one can make a real determination either way of longevity until they are out...
