Cummins Onan says it's discontinued (12 volt version) and offers no xfer. Need a new old stock version, or a current cross reference to a champion or NGK or similar. this is for a Onan 7.5 MDJE.
I have some antifreeze coolant collecting in my engine pan below the ONAN MDJE 7.5. She will run for 4 or 5 hours and then shut down for overheat. We add about 3 cups of antifreeze to the tank, and away she goes. I have checked all the hoses on both sides of the water system and I cannot find...
One blade with slight damage from shallow encounter with mud bottom. See pictures. Make offer for the pair or message me with questions. GT Correction to listing title: Should read "C399", not C300.
Our ONAN 7.5 MDJE suddenly started blowing black smoke and spewing diesel fuel into the water yesterday. It continued to run, but we shut it down within 10 seconds. Initial concerns are possibly one cylinder dead-heading, or other serious failure. This is a very old unit leaving us the...
I have a friend of a friend who says he was just charged $85K to clear through the Panama Canal. We are trying to back into the math. Can someone give me the short and simple on how to calculate your cost to clear the panama canal?
Thanks,

Does anyone have specs on the amp draw for the 120 volt Euro Kera forceio 2 burner ceramic cooktop? We are tripping breakers and the panel amp guage is broken. Thought someone might have the wattage and amp rating handy...
THe AC panel ammeter has failed on my 120 panel. I have 30 amp service and further inspection on the inside of the AC cabinet shows a large sand colored donut that appears to be part of the gauge, apparently around the main power source wires from the Shorepower inlet to measure amperage...
We need an aftermarket -multi fit bow pulpit for mounting across uneven surfaces on the bow of the Bertram. Open to any adaptable solution, but will need to work with 45 lb claw Manson Supreme anchor. Don't want the cost of integrated handrail. Just trying to solve the problem logically. Many...
Over the last 6 months, the minimum idle to avoid setting off the low oil pressure alarm has gone up for my starboard 671 turbo. It was originally about 680, but is now up to almost 800. This engine shows about 40 lbs at cruise and right under 20 on electronic guages (no mechanicals installed)...
I have the rebuild kit for the raw water pump on my Onan 7.5 MDJE. The shaft sheared in half so disassembly was not clean. Now I am not clear how the two part seal and spring go back. If I understand correctly, the rubber and white portion of the two part seal gets dropped into the deep end of...
I need an Exhaust manifold for my Diesel ONAN MDJE. The Cummins Diesel part number is 154-2122, which superseded the original part number 154-1058 for the heat-exhanger version of the manifold.
The end where the nipple and Exhaust elbow attach is rusted out. The inner threads where the 1...
I was servicing the genset last weekend and fired it up from the bilge after an oil change and fuel filter change. It has developed an exhaust leak at the joint where the manifold goes into a pipe that later feeds the through hull pipe. This union is behind the Genset, and right under the...
I have a Bertram 42 FB that never had a windlass fitted. I need to add the windlass, bow roller, anchor, chain and rode. I believe wiring is in place under a cover plate on the heavy line turn-block on the nose.
Here are the controlling constraints:
- The bow has a large block installed...
Just did an oil change, took out a lot more oil than my multifit manual says must go in. Am concerned that the rotated engine install used in a Bertram may use a unique oil pan. (Hatteras was straight up, wasn't it?) The multifit manual shows 2 pans, one very shallow (clearly not mine) and one...
Guys,
My '76 starboard 671 Turbo (4 Valve) is getting worse. We had a raw water impeller fail two weeks ago (185-190 degrees before shutdown) and misdiagnosed as a thermostat. Replaced that, retested and with new IR thermometer quickly found raw water impeller housing overheated. Engine got...
My big flybridge dash rewire project had a casualty: neither water temp gauge will operate and that kills both at the lower helm as well. There were a few wires difficult to label and photograph and it turns out it affects water temp. The sender wires are bright yellow and there is no other at...
My starboard engine is a little more smokey this year than last having owned the boat 2 years. The port engine (DD 6-71s) was rebuilt in the 80s and the starboard one is a little weaker. 25 lbs oil pressure at idle, good compression, no obvious issues, just smokey with the throttle up.
A...
My flybridge guage panel was metal and the Stewart Warner gauges oxidized and failing. I had a new panel made by a guy that does Sea Ray panels with a CNC router out of the black material with routed white letters. That panel has rectangular 1.450 x .83 cutouts and he provided some Carling...
