Wolverine heaters

November 7, 2022 at 8:33 pm I have to say I’m impressed…..new to us 1999 Albin express trawler with twin 6BTA engines. Previous owner installed these heaters on the sides of the oil pans….access to the bottoms would be nearly impossible. We’re supposed to get some freezing weather this week so I turned them on Sunday…..went down today (monday) to check on them. Used an infrared thermometer and the coolest part of the engines were 65 degrees…..obviously warmer the lower I w…

Oil Pan Heating Pad Burning Though?
This topic has 7 replies, has 4 voices, and was last updated by

November 6, 2022 at 2:42 pm Hi Everyone – I am now just about to install my third oil pan heater on my starboard engine. Zero clue why but it keeps frying. The first two looked similar when I peeled them off. Has anyone else experienced this? My port pan heater has been running with no problems and is plugged into the same outlet as starboard. Attached are pictures. The bottom of my pans are clear of paint, but now it looks like some of the adhesive (yellow pa…
7 RepliesNovember 16, 2022 at 11:44 pm Had a good talk this afternoon with engineer at Philip and Temro. I then went to the boat to apply some of my new knowledge. Turns out the multi outlet extension cord running from my 110 outlet to the Block heaters had a intermittently Bad socket driving me crazy. So both heaters are up and running. We also discussed the other heater that I could never get to adhere to the oil pan I so carefully prepared. I did get The replacement heater I purch…Last Post by:

Build a lift muffler
This topic has 2 replies, has 2 voices, and was last updated by

October 24, 2022 at 11:26 pm I’ve got a big in-line wet muffler, about 12” diameter and easily 36” long, 5” in and out. My take on it is that it’s so roomy inside that it does little to reduce sound level. I’m wondering about the feasibility of converting it to a lift muffler in hopes of making the exhaust quieter, adding a starboard side exhaust for North Sea style outlets. <br />What I don’t know is if there are certain specifications that I need to follow in buil…
2 RepliesNovember 7, 2022 at 5:08 pm Please excuse my ignorance of terminology, is 3”x 3 or 3.5” mean that the exit tube is 3 or 3.5” off the bottom of the muffler? Also, I notice that all the commercial lift mufflers are quite short (vertically) , would making it taller make it quieter? I found this drawing online that is just what I want to replicate.Last Post by:

Wolverine Heater location
This topic has 3 replies, has 3 voices, and was last updated by
1 year ago October 25, 2022 at 8:15 pm Is there a preferred location to install a wolverine heater pad on a B series, Meaning the rear or the front of the pan or does it not really matter?
3 RepliesOctober 27, 2022 at 5:21 am As to the original question, as long as it’s on the bottom of the pan on a completely flat area that is all that matters, remember its for long continuous use so the entire pan gets heater and radiates upward.. Scroll down on the below page. Installation requires a coarsely scratched, clean and dry surface.https://www.sbmar.com/product/wolverine-oil-pan-heater-model-25/Last Post by:

1 year ago June 29, 2022 at 1:31 pm Love my wolverines but after a year and a half it seems one has failed.Doesn’t seem like there is any trouble shooting to do as basically there is just a plug and a pad.Anybody have to take one off and replace. Seems like a pain to remove.I was hoping for more than a year and a half.outlet is fine.Bill
14 RepliesOctober 20, 2022 at 3:18 pm Tjborro I found those on Amazon. I was considering them also but the reviews weren’t great.About 100 bucks each.One reviewer said he got about a year and a half on his in the marine environment.But if you read all the reviews it’s hard to buy anything.They would seem to be a perfect solution if they last.Let us know.BillLast Post by:

Exhaust tube replacement QSB 5.9

October 7, 2022 at 5:17 am There are some cracks and splits in the first 12″ or so which I have wrapped and the insurance company wants to see it replaced. Providing the last 5 ‘ are in good condition do you think I can use a fiberglass sleeve and add on a new section for the first few feet??
2 RepliesOctober 8, 2022 at 7:24 pm Why is it cracking and splitting? Could point to raw water supply problems, lack of support or vibration damping, or simply old age. Your insurance company shouldn’t have to tell you when maintenance is due…Last Post by:

October 2, 2022 at 1:07 pm Here are the basics. Would very much appreciate thoughts regarding potential source of the issue and actions (if any) to be taken. Thank you. QSC 540 with 2660 hrs. Elevated aluminum in oil sample a year ago (25ppm). 80 hrs on oil. Oil changed after sample taken. Elevated aluminum this year in oil sample (29ppm). 60 hrs on oil. Report attached.

5 RepliesOctober 7, 2022 at 4:46 pm I removed the condensation drains on both AC’s. These are the check valve versions that close with a few lbs of pressure. The drain on the engine with the offending oil sample was clogged and the AC was holding a small amount of fresh water (it has been a few weeks since I ran the boat and I presume there was more water at shut down). The drain on the other AC worked fine. I suspect that the AC has been holding water after each run for…Last Post by:

6BTA 370 Voltage drop while starting

April 16, 2022 at 10:57 am How much will your voltage drop when you engage the starter ? I have 2 relatively new 31 east Penn gels in parallel and my voltage drops from 13.4 to around 9.7 is that normal ? I just installed some smx voltage gauges and that is the reading I get.
8 RepliesOctober 1, 2022 at 6:30 pm Wow, I was just writing this reply and finally realized this thread is 6 months old. Opps. Oh well, I will leave it as it may help someone else. If one battery is failing the parallel connections will show a good average voltage high enough to make things look OK. The meter will likely show a good average voltage. However as soon as you try to crank the engine the failing battery will cause that average to drop big time. I have…Last Post by:

From dual V belt to serpentine
This topic has 3 replies, has 3 voices, and was last updated by
1 year ago June 20, 2022 at 8:23 am We have a QSL9 and in addition to the standard alternator, we have a 300 amp Balmar alternator that charges our large house bank. It has a custom bracket near the front of the engine and uses a dual V belt setup from a crank mounted pulley. We would like to change it to serpentine as we have had constant trouble with getting two v belts (matched), hence one slips and smokes. Seems like the pulley for the alternator is easy to source, the crank …
3 RepliesSeptember 28, 2022 at 5:54 am Clark, HTD belt systems are great, but require much more care in building proper brackets as to alignment, etc.. I have made many “gizmo’s” using them for high torque lower RPM applications — Harley Davidson has used them for 20 yrs+ now. The belt of choice for blowers in dragsters, etc. Double V-belts, done right are more way more forgiving–I suspect our original poster was not willing to spent to time need for…Last Post by:

Stainless Fittings on ZF trans?
This topic has 2 replies, has 3 voices, and was last updated by
August 7, 2022 at 9:15 am I’m servicing my two ZF-80A transmissions with new Seaboard coolers/hoses/filters and want to replace my rusted steel hydraulic fittings on the top of the transmission. Can I use Stainless hydraulic fittings or should I stick with Steel? The ZF casting is aluminum so I don’t want to induce any corrosion. Sbmar sells stainless fittings but they don’t specifically say for transmission use. Just wanted your take.. Thanks again…
2 RepliesSeptember 27, 2022 at 5:31 pm Generally unless the metals, in your case steel or SS in contact with an aluminum casting should not suffer any corrosion UNLESS the parts are being wetted with salt water. That may produce some corrosion but it will be slow to develop. I suggest you cover the stuffing boxes with an old ,small fender you can cut to produce a cover. THe cover will stop the spray from the spinning shaft from being flung around and travelling which w…Last Post by:

Warranty on Repairs by Cummins/Onan?
This topic has 2 replies, has 2 voices, and was last updated by
1 year ago
September 14, 2022 at 8:02 pm A general question about the warranty, if any, you get if you hire a Cummins/Onan Location to repair your Cummins engine or Onan generator? Apparently there are two types of Cummins affiliates: Cummins dealers (which can be a boat dealer or independent repair shop) and genuine Cummins Locations where all they work on are Cummins/Onan products and work either at their location or provide field service to larger boats. So, is there a difference i…
2 RepliesSeptember 16, 2022 at 6:57 am Thanks Tony, If I was selling my boat and one of the after survey conditions was me getting a fairly minor (about $2k) repair done on a 20 year old Onan. If this repair is done by a Cummins Factory Distributor there would be some kind of parts and labor warranty. Is this warranty transferable to the buyer? If not, it would be better to give the money to the buyer and have him do it…if he would agree to this.Last Post by:

Smartcraft Connect any good?

1 year ago September 13, 2022 at 8:07 pm I saw on a forum that Mercury came out with a “SmartCraft Connect” module that allows you to see your engine data on a Garmin MFD. Applies to QSB and newer motors. Does anyone have experience with this module? Apparently you can plug it into your smartcraft system under the helm and run a NMEA cable to your MFD. I’m looking for a simple way to show engine info on my Garmin MFD. Is there an SMX module that does this or …

6BTA 330 coolant overflow reservoir hose barb size
This topic has 5 replies, has 2 voices, and was last updated by
1 year ago August 6, 2022 at 11:30 pm Can I find out the size of the barb on the coolant overflow reservoir bottle. I think it is for 6mm hose size, that is 1/4 inch hose. one can fit 5/16 inch hose ( 8mm) firmly but it has a wafer leak. The header tank size is larger so a different size is needed on each end. Any suggestions. Thanks

1 ReplyAugust 22, 2022 at 5:52 pm This is just general. Make sure that the wiring , at sender AND at the guage, is tight and free of any corrosion. Even light oxidation can interfere. Make sure the guage itself is receiving full 12 v. It is not just the ground wire but all of it. Poor voltage to the guage will produce poor results. Check the sender.
