Yannis For sure glass in the holes that allow water to enter the cabin area. And add a third bilge pump next to that bulkhead. One of the best things I ever did for the boat. Keeps the cabin completely dry. But there are 2 more holes pretty much directly under the stringers. Leave these open. Then i...

Bill Fuller

Yannis, I feel I need to say something on this subject. You may remember that I have essentially the same setup as you. My cutlass bearings were installed May of 2000, that's 20 years. The boats has 6,645 hours. The cutlass bearings are still perfect! Obviously, my shafts were aligned perfectly from...

Bill Fuller

WAC Assuming you have a Borg-Warner velvet drive tranny, I would guess that the tranny has actually been rebuilt and the forward clutch pack was set too tight. I have seen this symptom numerous times and had the same problem the first time I rebuilt one. I have subsequently re-adjusted the clutch pa...

Bill Fuller

Dug You might take a look at the starter relay, which is located on the same block as the oil pressure sending unit and switch. clean terminals, check for broken connections etc. Maybe even try tapping it. Also, just to check the basics, you could jump the starter motor terminals which should start ...

Bill Fuller

Rob
Sounds like a good plan. Maybe replace the bearings just because you are in there.
Bill

Bill Fuller

Rob, One suggestion. When you set up the forward clutch pack on the velvet drives, set the clearance on the loose side of the spec. Foe instance, if spec is 0.030" to 0.055", set the clearance at about 0.050. These are not the exact specs but close and gives you an example. The first one I ever did ...

Bill Fuller

I use a Norcold dual voltage refer much as Jeff described (West Marine). I believe the current model number is DE-0041/EV-0041 My unit has been operating continuously for 15-20 years, can not remeber exactly. I'm set up so that when shore power is atached it automatically runs on 110 volts, as soon ...

Bill Fuller

Yannis, I am just leaving on vacation. Driving into Mexico. I will take some pictures of what I have when I return so you can see what works for me. My chain is 1/4 inch, I think, which is 6.35mm. I have used 3/8 inch (almost 10mm) in the passed and prefer it. But the windlass I have now requires 1/...

Bill Fuller

Yannis, The rope and chain combo has a lot to do with owner preference. 100% chain certainly gives you the best chance of holding. Many here in the U.S.A. use 100% chain, again a matter of preference. I use 60 feet and then the rest rode to make 400+ feet total. Everyone uses their boat differently ...

Bill Fuller

Stone Pony, Luke, Listen to all of the concerns posted above. They are all valid. Especially the lack of strength shown in the video. When you install a windlass, you need to do a substantial amount of reinforcing under the deck. First, remember that the chain is what sets the anchor. Normally the r...

Bill Fuller

Yannis, If you disregard the windlass, you are looking at a factory original system. The anchor sets in the chalks as shown in Joe's picture. Chain lays on the deck and feeds into the hawse pipe (see the rust where the chain was). Shown with the cover on the hawse pipe. Deploy the anchor by hand. Re...

Bill Fuller

Bob, Which 6 cylinder Yanmar are you talking about? There are several. The most pertinent to this group of boaters are the 6LP and the 6LY. Two completely different motors. The 6LY is the 6 cylinder version of the 4LH. And I think you agree, is a great motor. Bill PS, I am confused, what 250 HP Yanm...

Bill Fuller

In the case of Yanmar, one must ask which Yanmar, as there are a variety. Some are very good and others not so god (bad). The 6LP is a marinized Toyota. Driving the overhead cams with belts may be questionable but very common in the automotive industry and it is an automotive engine. Personally I th...

Bill Fuller

Greg
go here to see the Yanmar specifications for your motors.

Bill Fuller

Greg, First you need to understand your motor. It is completely different than Yannis or my 4LHAs. Your 6LPAs are not designed to cruse at 2400-2600 RPM. They are designed to cruise at closer to 3500 RPM. Your motors are rated to produce 315 HP at 3800 RPM and the Yanmar specification is for them to...

Bill Fuller

Greg, Yanmar spec for your motors is that they should turn an honest 3950-4050 RPM at WOT and fully loaded. Adjust the pitch in your props to obtain these numbers. if you have Yanmar tachometers be sure to check their accuracy with a photo tach. Yanmar tachs are almost always not accurate. Nice look...

Bill Fuller

Yannis, I keep talking about 6 cylinder motors because the key to fitting them into a B28 is the length of the engine compartment. There is plenty of width. Height can also be a problem but again, Bertram made these modification when they put the 6 cylinder motors in the boat. They are quite differe...

Bill Fuller

Yannis, A couple of B28s on this site with 6 cylinder motors. SteveZ has/had a B28 with 6BT Cummins, which I believe was repower from original 6 cylinder Volvos. RAWicklund has/had a B28 with factory installed 6 cylinder Volvo KAMD42. Again, these boats have longer and maybe taller engine compartmen...

Bill Fuller

Yannis and others, Those are definitely 6LPAs and are 6 cylinders (look at the 6 injector lines). The hull stringers have not been cut. They are not visible in the pictures as they are covered with a structure that has been built to fit these engines. Much like the original engine mounts. Also, reme...

Bill Fuller

Just on the off chance that there might still be some setting around at Seaboard Marine, give them a call. Mine were removed and in good condition but that was 17 years ago. I believe they were dismantling a B28 a while back. Any way, give them a call and see what happens. Tony is not there right no...

Bill Fuller

Happy Joe, I ran my 1975 28 flybridge cruiser for 10 years with the original small rudders, and Mercruiser 260s. I have run the last 17 years with over-size rudders and diesels. I have one comment: CHANGE THE RUDDERS! My experience includes about 3,000 hours on the small rudders and 5,500 hours on t...

Bill Fuller

Yannis, No problem, just curious. I usually just buy mine from local suppliers and there is only one length available. Years ago I could get shorter ones locally. Looking on the internet, I see you can get almost any length you want. When you mentioned you had just the one seeping, I thought you mig...

Bill Fuller

Yannis, Completely possible that Yanmar is providing you with shorter zincs than I am accustomed to finding. I do use after market ones, and I can only find them in one length, which is a bit long for the fitting on the side of the heat exchanger. Interestingly enough, most of the kits I find here o...

Bill Fuller

As a retired research chemist, also having dealt with lots of all types of chemicals and flows and some very high pressures, I agree with your statement 100% Whatever you put on the threads is there to allow the threads to mesh together smoothly (a lubricant). And prevents galling. And as Yannis fou...

Bill Fuller

Yannis The forward zinc on the heat exchanger should be shorter than the others. You should cut of about a 1/2 inch before installing. Otherwise it may be hitting the tubes. I change my zincs about every 6 months and over 17 years and 5200+ hours I have never had any issues. No seeping ever. I used ...

Bill Fuller

Which anode is giving you problems?
Is it the one of the ones on the end plate
or the one on the side, forward on the heat exchanger?

Bill Fuller

Steve, Send me an email. I am also in San Diego. I may be able to help a bit. There actually quite a few B28s in San Diego. I have a 1975 which was delivered with 351 Fords, was repower with 350 carbed Chevys in the early 80s and now has Yanmars. As a start, there are at least 8 different deck confi...

Bill Fuller

I don't consider myself an expert but I have a pretty good understanding of these motors. So, to start with, all of the 4LH "S" motors are rated to produce the exact same HP under the exact same conditions. I have always looked at the 4LHA motors as an upgrade over the older 4LH motors. Different af...

Bill Fuller

I can not provide any direct information on the boat. But I have noticed it routinely as it is slipped at Dana landing where I fuel. The boat has always looked to be well maintained and cared for. It looks good from 40-50 yards and we always seem to comment on it as we pass. As Bruce mentioned, the ...

Bill Fuller

Jack, A couple of thoughts: I don't think there is a design problem. I have been around a number of 4LHAs, including my own, and I have never seen or heard of this problem. As Kevin mentioned it could be growth, or it may be rust. Either way I think your primary filter system may not be doing the jo...

Bill Fuller

Hank
Off the top of my head I can think of three places where the coolant could exit the system without being in the bilge.
Heat Exchanger
Exhaust Manifold
Turbocharger
Everything else is raw water cooled.
One question, what kind of coolant do you use? This is a very important question.
Bill

Bill Fuller

Jack and Yannis, As Kevin said, you do not have a lack of feel but a lack of air. So first question, Have you had the running gear thoroughly cleaned, the actual bottom is less important but also needs to be clean. Here in Southern California I have to have my bottom cleaned every month. If you skip...

Bill Fuller

Ernest, I would had one comment to what Bruce said. After you have all the air out at the top of the fuel filter, close it up and attempt to start. If it does not immediately fire, have someone operate the pump while you crank the engine. This will often help push the last remnants of air out of the...

Bill Fuller

Mine have 4,200 hours on them and I honestly expect to get 10,000 hours. No oil burn and they run just like they did 15 years ago.
Like all other marine engine, you have to keep up on the maintenance.
Fantastic motors!
Bill

Bill Fuller

A couple of years ago I had one of my tachs start acting up. I suspected a bad connection at the sender, and as you have experienced, it was hard to find.
Next time I am at my boat I will find the sender again and try to post a description of where exactly it is and how to find it.
Bill

Bill Fuller

Yannis, Do you have Yanmar tachometers? If so, they are not driven from the alternator. If some other brand they could be driven from the alternator, but that would be unusual. My Yanmars tachs are driven from a sending unit that counts the teeth on the flywheel and is mounted on the bell housing. I...

Bill Fuller

All of you need to talk to Tony Athens at

sbmar.com

Either custom or stock. But the bigger question is why you need to replace. Also, fresh water flush after each trip will greatly increase the life of mixing elbows.

Bill

Bill Fuller

I would think the Volvos would do you very nicely in the B28 Moppie. I have the same setup as Yannis and Hyena Love but a few more hours. Half tower with eissinglas all around, 100 gallon live well and the 162 gallon fuel tank (which means about 150 gallons of fuel). And loaded very heavy. Just last...

Bill Fuller

Jay, The 1991 model should be a really nice boat. They got really nice toward the end of their production run (1993 I think). I assume you have the 240 gallon fuel tank. My boat is a 1975 model and was delivered from the factory with 351 fords. These were replaced in approximately 1984 with the Merc...

Bill Fuller

Jay, I agree with what Tony and Scott said. Was the oil milky with water in the valve train when the valve cover was removed? This would be a good indication of water in the oil. I would try to have that head re-worked if possible. There are a lot of different 350 Chevy heads and you want to be sure...

Bill Fuller

Jay, Did you look at the valve train before the head was removed? If so what did it look like? Oil wise. Did you look at the cylinders when the head was removed? What did you see? Straight, clear water or coolant? Were the cylinder walls rusty? If so, how rusty, just a little surface rust? It is ver...

Harry,

Still curious,
Which 4LH motors do you have?
4LH-DTE
4LH-STE
4LHA-DTE(P)
4LA-STE(P)

Bill

Bill Fuller

Harry, I run a similar set up to Eddy's with similar performance. I like to run the motors at between 2500 and 2800 RPM. I have limited my continuous cruise RPM to 2900. It just seems like the motors start to really work hard above that RPM. What 4LH motors do you have? what is your gear ratio? What...

Bill Fuller

Go to
www.sbmar.com
And look under repowers at Audax (toward the bottom, my boat) and Noelle Mae.
Both removed the large old wooden engine supports.
Mine have been in operation for 15 years and 3,800 hours with no issues.

Bill Fuller

Kevin, I don't know if your gear is similar to my Hurth 630As (ZF 63A) or not. I had a similar problem last year were I suddenly had a transmission leak. It drove me nuts for a few days, and like you, lost sleep over it. Mine was a significantly bigger leak than yours and took a while to isolate. Al...

Bill Fuller

Bob,
My plan is very similar to what you describe. The box will follow the contour of the hull, but will set in "cradles" that the old auxiliary fuel tanks sat in. The boxes should have a capacity of between 45 and 50 gallons.
Bill

Bill Fuller

Bob,
Agree, screws alone would be risky even though I am cored with Coosa Bluewater 26. My hinges will be through-bolted.
Bill

Bill Fuller

Thanks Bob, At this point I will probably just go with the hinges in the link above. I am in Florida right now and my son is working on the deck back home in San Diego. I think he is trying to finish it up before I get back. He will be fitting the hinges and latches this weekend. And then it will be...
