I'm very glad I found this post..... I had to have replace my turbos (4BT's/28' FBC) because I used the factory wet elbows and over time salt water rusted the exhaust housing horribly...anyhow I bought 316L stainless tube and created my own dry exhaust that utilized all of the engine room height bef...

conchy joe

Glad your back on the water.

conchy joe

I too have a 76 28' FBC and upgraded to larger rudders. They are the BEST! I can troll on one motor easily! If you go with the 31 rudder, the post is different. On the 28 the rudder arm go below the rudder shelf, but the 31's the arm goes above the rudder shelf and are not interchangeable. My rudder...

Does anyone know the exhaust housing volume for the 150 HP Cummins 4BT. I have checked for air pressure leaks on the intake side and found none. I'm only making about 5 psi of boost at 2000-2100 RPM. I would like to get 10 PSI of boost at the same RPM. The reason for the needed boost is that when lo...

conchy joe

Any chance you would donate one of your old bow cleats to my project? I would pay for shipping.

conchy joe

Frank, I was sorry to see the problems you had. I just turned 250 hours on the 4bt's I rebuilt and did the valve lash adjustment myself. I was very concerned that I may screw it up and drop a cable too. Luckily I have put about ten hours on the motors since and everything is fine. How is your projec...

This boat is about two miles from me. I spotted it about two weeks ago and talked to the dealer. He said the boat is built in NC from the original 31 mold.

I am in the process of redoing the interior of my 28 FBC. I have gotten rid of the large closet just behind the v-birth and relocated a large top opening refrigerator there. The top of the refrigerator is the same height as the galley countertop. I move the AC unit from under the front dinette seat ...

I placed the genset to the outside of the starboard motor and it's LOUD. I may put the fiberglass sound shield back on once I have 100 hours on the genset as it was used and I have found that someone tried going through it and I have found quite a few things that were ass backwards. We will /sleep o...

conchy joe

Luckily I can pick up locally. Thanks.

Anyone else have any comments/ideas?

conchy joe

Faithful, I am getting ready to move on to sound insulation in the engine compartment of my 28 FBC. I just installed a Panda Fisher 4.2kw geneses but am leaving the sound insulation/fiberglass box off because I want room to do maintenance, etc, on it. This is my first 3600 rpm generator and boy it i...

conchy joe

Kevin, I cut mine out last years to recess my transducer, per Capt Pat's building tip. It's never caused me any issues. Also, I FINALLY got my 5" exhaust in, turbo's freed up, generator rewound, reinstalled, and have put some miles on the boat locally. Now we are trying to make it look pretty. Sorry...

conchy joe

Faithful, I was planning a trip Monday to the Bahamas with Kevin and company, however I recently installed a Fischer Panda 4200 genset and its not making any power. I bought the unit about a year ago, it ran fine and made power under a full load while in my garage. I installed on the boat a few mont...

conchy joe

I can leave anytime after July 14th.

conchy joe

Just picked up some 80 diviny cell 3/4" and two layers of 10oz and vacuum bagging supplies. Will post some
pictures.

conchy joe

What thickness? 1/2 on the diviny cell? I'm doing the entire deck

conchy joe

By coincidence, my project this weekend is to re-core the deck on my 28, I have two soft spots. I was planning on using divini cell, however I don't want over/under engineer for stiffness. Capt Pat, after cutting the back side of the deck off and coring material what layup schedule would you recomme...

conchy joe

Anyone know the ballpark figure of what these cost? Any cons to their product?

Thanks

conchy joe

That sounds better.

conchy joe

When I was there three years ago they wanted $4.25 a foot with a 40' minimum for dockage. We spent the night on the hook, just out front.

conchy joe

I talked to the guy at the show and I saw a sister boat to this one two years ago in the Abacos, with Suzuki's. As I remember they are actually 25 Bertrams that have been stretched, the bow flare changed and a 31 style chine added. I could had sworn its a twin engine boat and not a triple. I take th...

conchy joe

My only concern with the batteries mounted at the bottom of the bilge is that if you have that small compartment flood to the top of the battery, with salt water. The batteries will short, the engine will stop running, the bilge pump(s) stop and your two way radio would be dead. If the batteries are...

conchy joe

Cant wait to see it done.

conchy joe

Looking nice!

conchy joe

While I am redoing the rear bulkhead/windows and raising the engine hatches on my 28 I think that I will incorporate this project also. Thanks Capt Pat.

conchy joe

Thanks. Marlin that would be great.

conchy joe

THANKS….. That was exactly what I was looking for!

Any ballpark idea of what I would expect to pay for the custom cut glass? and any recommendations on a company to supply the glass? I'm in the West Palm Beach area.

conchy joe

Ok, so I did not want to but I had to raise the engine hatches on my 28 FBC to accommodate installing a Fisher Panda generator on the port side, outboard of the motor. As the rear bulkheads are out now and the original plywood panels weigh a ton and the original windows are fogged I was contemplatin...

conchy joe

I have always tried to avoid going to Bimini on the 4th of July weekend. If we had to start the trip that weekend, I would suggest avoiding Bimini and going to Cat Cay to meet up, or if you wanted to be on the hook, Honeymoon Harbour.

conchy joe

We are definitely in!!! Just a suggestion for the trip. Cat Cay (pick up a bunch of conch) spend the night, next day run to Chubb spend the night and fuel up. Head south to Fresh Creek, Andros spend a couple of days, work our way back up to the Berry's (get some more fuel), spend a few more days, th...

conchy joe

I'll be there. Not sure which day/days.

conchy joe

I had the standard airman B744 thru hull on a high speed fairing block and it worked ok. I'd loose bottom at 300' at cruising speed and I would get all kinds of funky returns on the screen. I decided to make the hull transducer cavity in Capt Pat building tips section. OMG, what a difference at crui...

conchy joe

The good news is its nothing money can't fix.

conchy joe

Can't answer you on brands. I forgot what I went with, but my understanding is the 28 backing pad is fine unless yours have issues.

conchy joe

Ok faithful, I working out the tweaks, on these new motors (cummins 4bt's on my 28 FBC) I have installed manual 0-30 PSI pressure gauges in the plug fittings on my intake manifold. I used a pressure boot over the turbo intake and pressurized the intake to 10-15 psi with the motor off and corrected a...

conchy joe

I agree it does look great on some boats, but probably overkill.

conchy joe

So, we finally got done enough with our gas to diesel repower to actually try to use the boat. Our local marina sponsored a trip from Boynton Beach to Bimini this past weekend and for the past two months this trip has been our goal to get the boat done enough to take it. We had 12 hours on my first ...

conchy joe

Kevin,

I agree with Charlie J, take the four strut bolts out and drop the struts. Thats what I did and then VERY carefully used a saws all to cut nearly through the old cutlass bearings. I then collapsed the cutlass bearing and out they came. Took me about an hour total.

conchy joe

Thanks but I actually found the cummins part yesterday.

conchy joe

I currently have the Cummins 4BT and I am wrapping up my gas to diesel conversion on my 28' Flybridge Cruise. In order to get the center engine deck lid down I need to remove the coolant tank from the port motor and will put a remote tank in. My question is, I am looking for a cummins part number fo...

conchy joe

All right, the diesel repower project is on the home stretch. I made a couple of partial power test runs up to 1800 rpm in the ICW and each one has had its abrupt end. I am happy that I have 50 PSI of oil pressure at idle with a hot motors. There is no smoke at idle or partial plane. I trashed a new...

conchy joe

I think I have a Delco style alternator and I am having a fit trying to figure out which wires go where. I know the the BAT wire is for the battery, but there are two spades on the side of the case and a second post with a nut and of course the ground bolt. If my thinking is correct I need to hook u...

conchy joe

The problem is my exhaust pipe is water jacketed. How would I overcome that??

conchy joe

All right my compadres. I'm getting closer to sea trials and want to add egt sensors to my cummins 4bt project. I want to add egt sensors pre turbo. Is there anywhere you tap the turbo or manifold without striking the water jacket? If not I was thinking about drilling and tapping turbo housing post ...

conchy joe

I pulled the motors out of my 28 last year while still in the water. Neighbor had a davit lift on his seawall and it worked great. The gas tank was empty so I did not even have to plug the exhaust.

Good luck.

conchy joe

Just because you can, does not mean you should.

conchy joe

Here's an update, I pulled the pump off the second transmission and put it on the first and voila, great pressure and the tranny seem to work fine. I found a used pump from a place in Washington and hopefully next weekend I'll have two trannys that work.

Thanks everyone!!!!

conchy joe

HAPPY NEW YEAR...Here is an update. As Bruce recommended I cracked the oil cooler hose and no fluid. So I take the four bolts out of the back of the oil pump and the shaft on the pump is sheared....WTF! The pump turns freely, so I take the oil pump support housing off and the pump coupling is trashe...

conchy joe

Bruce thanks for the insight. I will crack the lines to see if I have flow.
