I installed almost the exact same configuration last year and while its working perfectly at the moment, this is great information to have. Thank you so much for sharing, and good on Balmar for going above and beyond.

Hey Charlie, Brian had a kit that includes the two gauges for helm and flybridge and a dual staton sender for $100 bucks each (I bought one kit for the oil pressure gauge, and one kit for the coolant temp so $200 total). He said the brand was Vee Three. I also bought an expansion tank gasket...

Hi Folks, I didnt get any traction here but I figured I would reply with the answer to the question for any other lehman 120 owners out there. I spoke with Brian at American Diesel and not only did he have the right gauges and senders for my replacement, but also confirmed the thread size which...

Hi All, 81' CHB 34 trawler owner here. I'm replacing my old original AC delco temp and oil gauges both at helm and flybridge with modern VDO ones. I'm looking at dual station senders and am wondering if anyone knows the thread size of the temp gauge sender. I'm not able to get to the boat for...

Thanks all, lots of great info here. I figured I wasn't the only one who worked on a project like this. A little more info that might help frame the situation: The Balmar upgrade is in response to my 90 amp leece neville alternator actually failing on my last trip. I spent three days on the...

@O C Diver - totally agree with your comment on having spares. I have not one, but two pre threaded spares ready to go. Because the belt isnt going to fail at the dock! That said, knowing how reliable serp belts are I may just bite the bullet and convert to that and carry a spare pre threaded...

yeah, that makes sense - if the material rides high enough to not contact all of the surface area on the crank pulley I may only be getting higher durability on the thicker belt but not more horse power to the alternator. This may be one of those situations where I'm talking myself into...

Hi All, I am in the process of upgrading from a leece neville 90 amp alternator to a balmar series 621 single pulley 100 amp alternator. I currently have a 3/8 inch v belt driving the alternator and water pump on my engine. My understanding is I should upgrade this to a 1/2 inch belt to...

If they ever open a grand banks museum this could be the main exhibit. Beyond that, I really don't think that price could be justified considering the number of really well maintained/restored GB 42's that are out there for way, way less. Frankly, with that mirror finish Id be afraid of ever...

@comodave - I probably can but not without some considerable effort (then again, what job in boating doesn't require some cussing and bloody knuckles). You know how hoses are - you take em' off and usually just have to replace them after working them so much. If I'm fiddling with it that much...

Greetings! I have a new to me 1981 CHB 34 tri cabin with its original Lehman 120 with hours just shy of 4000. The boat had meticulous maintenance records until 2011 but the PO I purchased from only had professional mechanics work on his boat (a good thing) but didn't save all the receipts. So...

Thanks - that was going to be my next question. The chinese units are like 150 bucks wheras the espar d4 is just shy of 1k. Ive even heard that the newer espar units require just as much fiddling and am seriously considering the chinese knock off. Has your friend voiced any safety concerns...

Thanks - yeah, with that kind of amp draw the nuisance tripping on the 80 amp breakers between the acr and the house and on the other side at the bow thruster bank on the positive feed is totally unsurprising. Everything else about the install of the thruster looks like great work done by a...

Hi folks, I bought a 1981 33 CHB in november and found the old diesel heater onboard nonfunctional. The heater is old - its the original espar d3l model from the 80's. Im always one to try to fix the original item rather than jump to replacing it but Im wondering if I should just buy a...

Yeah, it occurred to me that I could simply use a 110 volt ac battery charger and run my inverter while underway to charge the thruster battery. I could also replace the combiner with a dc-dc echo charger (this is how I charge my start battery from my house bank). I suspect the original...

Thanks All, this is a lot of good information. @Kiwi - I suspect if you are right about the fullriver being rated at 1150 cca then its simply a bad battery. My tests showed it at 650 cca which is almost half of its rating. This boat is new to me as of November so its entirely possible the PO...

I have a bow thruster with a dedicated group 31 115 AH full river AGM battery. The dedicated battery is recharged via a connection to the house batteries (600 AH of AGM northstar Batts) about 7 feet away via a blue seas ACR/Combiner with 80 amp thermal breakers at both ends. Ive noticed when...

Im looking for a used but in serviceable condition complete winter cover for my new (to me) 1981 CHB 34 trawler located in everett, WA. My boat was boathouse stored for years and I'd like to keep it as dry as possible now that I have it in open moorage. Ideally it would be a canvas cover that...
