Cobalt Boats Forum

Then I'll probably try to put the exact battery Cobalt put in when it was new when it comes time to change. The local Cobalt dealer here mentioned that Cobalt themselves don't put batteries in the boat - it's part of the dealer prep before delivery, so the battery brand may be different for each Co...

You need to look at your owners manual to see what the Marine Cold Cranking Amp spec is for your engine. For my Mercruiser, the spec is minimum 800MCCA. The Interstate size 27 deep cycle has only 750. The reason is that some batteries have too much voltage drop while cranking to reliably operate fu...

Sometimes they'll change the cam and/or the throttle body, but with Volvo Penta in particular it's often just a different engine tune.

Which Interstate batteries where you talking about 27DC Marine Battery or the 24DC Marine Battery Thanks. They're the same construction and materials inside, only the group 27 battery is a bit wider than the group 24 battery so delivers a few more amps. Group 27 batteries will usually fit in the sa...

Spoke to Garmin...they don't make an adapter to go from the hole for the 7607xsv to a current model. I will 3D print my own adapter once the time comes. I also have a friend with a CNC milling machine that will make me one based on my 3d printed design Makes sense. When I put a new radio and remote...

Not sure which model I have and I’m not near the boat to poke around. Here’s a pic of the 2… Pretty sure yours is the next model up but I believe it is also discontinued since I was looking for one to buy. It would have been close enough to fit my boat with a little bit of filing plastic! Looked ba...

I figured Duracell car and boat batteries were just a money grab to trade on the good name of their AA, 9V, etc. consumer batteries, but their lead acid batteries are pretty consistently rated highly by places like Consumer Reports that do actual testing.

If you want Cobalt original stuff it may be available from your Cobalt dealer, but Cobalt typically won't want to sell to you directly.

Just following up. I white flagged it and had a tech check it out during the annual service. It turned out to be a loose deustch connector to the sub - hope this helps someone in the future. Thanks for the suggestions. Thanks for reporting back, and glad we were on the right track with our advice!

I think there are really only a few battery makers out there, labeled as lots of things (Johnson Controls, Delphi, East Penn, Exide?). Johnson controls brands include Duralast, Interstate, Diehard, Kirkland, Motocraft, and others, and I've just bought Interstate dual purpose marine batteries from Co...

There are several vendors out there that will do it, including:

There are two recent Volvo Penta V8-300 motors out there - the 5.7L (which the 2015 boat likely has, but tweaked a bit to become a V8-320) and the 5.3L (which the 2017 boat likely has). The 5.7L has a cast iron block, is a bit heavier, doesn't have direct port fuel injection but is fuel injected, an...

The V6-280 has variable valve timing and advanced fuel injection that the V8 doesn't, and is a bit lighter (903 vs 1022lb dry) due to its aluminum block and smaller overall size. Add the newer tech like direct port fuel injection, and I don't think I'd feel at all bad about having the V6 280 instead...

The change in boat quality is real, but the amount of change you'll see in the same boat design between 2015 and 2020 probably isn't all that great - your best bet is probably to give each boat a thorough look-over and pick the one that has the fewest problems or flaws and feels right to you. I like...

Shadow caster should be able to integrate with the garmin on the NMEA 2000 backbone. It should also be able to use the factory button to turn on and off as well as the mfd https://www.shadow-caster.com/products/marine-led-lighting-controls/nmea2000-lighting-control-multi-zone-lighting-controller/ N...
