    Caterpillar 3116/3126 engine oil availability

    does SEBU6250-30 superseed SEBU6250-29? I couldn't find a copy of 29, but 30 from 2020 says to still use SAEO 30 and/or single grade API CF oil for 3116/3126 Marine. SEBU6250-30: https://caterpillar.scene7.com/is/content/Caterpillar/CM20210119-674b3-bd997

    Have you replaced your fuel filters recently? If not I would. I had the same issue and my fuel filters we're nasty. Works great now.

    Save your transmission modifications

    ttmott, Any updates since this install, lessons learned or anything? Do you think you could have tapped off the existing Sea Ray analog system monitoring module in the bilge? Added any alarms or connected bilge sensors? My Sea Ray System monitor with the red LEDs stopped working, so thinking...

    OFFICIAL - 450DA Owner's Thread****

    Has anyone replaced or upgraded the original red LED System Monitor on the dash? I realized mine stopped working. I hit the test switch and nothing happens. Getting 12v and ground is good. When I unplug it and plug it back in it gives a faint chrip, but only life it gives. I was thinking maybe...

    System Monitor to replace idiot lights ...

    Skybolt. Just realized my LED System Monitor stopped working. How has hooking the rest of the system up to the AlbaCombi worked out? Were you able to hook up things like the emergency bilge pump, the other bilge pumps, oil pressure, water temp, transmission alarms and such from the Sea Ray LED...

    Fuel Tank Replacement 400DA

    Thanks for the photos and ideas. The leak was discovered in 2011, so hopefully port is good. Port is 100% full, so I imagine difficult to scope. Stephens13, do you recall what it set you back and the cause?

    Fuel Tank Replacement 400DA

    So I've asked an adjusted price of $10k, so if thats the repair cost then I'd be ok with it, and save it for winter. The previous owner ran a fuel line for the generator to port tank. As for what caused the corrosion we don't know yet, but there is new fresh water plumbing in the bildge, I...

    The big old 80's 340 owners thread

    Why wouldn't you want to lighten the load to a fuel injected 383 / 6.3L? That's what most sites recommend if replacing with gas. Seems like a better power to weight ratio, and should be better on fuel too...

    Freygreer- The previous owner repowered my boat in 2009 with S&S Rebuilt engines. They've treated me well :) I think I even had warranty on them up until recently. But yea, it was just a core exchange for the same engine model/type, so no real performance upgrades...

    I know not worth the $$ to convert, but wouldn't it have been nice if our 340s came with the Yanmar 6LP diesels!!! Check out these performance improvements in a 1986 390DA: 1986 39 Searay 454 gas to Yanmar 6LP diesel 40 gph at 18 knot cruise to 18 gph at 26 knot cruising speed!!! I saw a pair...
