Turns out my suspicions were correct, unfortunately. Found water in the 3 right side cylinders. Head was pulled and valves were removed. Found a 2" crack above one of the intake valves. Time to break out another... After installing a new head, some serious flushing, and oil changes it...

Batteries are fine. I can't test the charging system because it won't turn over fast enough to start. I'm waiting to hear back from the mechanic to have him take a look. I'm really thinking I blew a gasket and have water in some cylinders.

As I was thinking more about it this morning I though it was a possibility. Man I hope it's not that. This is the 3rd season on these manifolds, risers and elbows. Really hope that's not it.

Yes I tried the parallel switch and there was no change. My battery charger has a test button and it shows all 3 as fully charged. I didn't check this yesterday and I'm thinking since it's the same this morning that the battery never drained in the first place.

OK so after the battery charged all night and it's reading over 13 volts on all 3 (the one for starboard engine is isolated) the engine still only turns very slowly a couple of times, but this morning after trying it a few times i can hear an arcing sound and i caught a whiff of electrical...

This morning the battery is totally charged and the engine barely turns over. I cleaned the terminals (even though they looked perfect) and it turns just a little and pauses and again. I'm thinking its a starter issue. Crawling down there now.

Thanks for the replies! I don't have a volt meter. I'm heading there in a little to see how the battery is charged and to see if it'll start. When I start it i'll look and see what the gauge says. Before the trip yesterday it was fine at about 14 so i'm hoping to see a drop....at least this...

Returning back from lunch today everything was going great until I came down to idle. Starboard engine started idling very low (300-400) It ended up stalling. I tried to start it back up and the battery would only turn it a couple times. Now this sounds like the alternator went, ran the...

I called the number on the Sam's website. It was the customer service number at Eastern Penn Manufacturing. The batteries you bought at Sam's are, in fact, dual purpose. The rep told me that anything that is AGM is a DP battery. I was able to find the same battery at Batteries Plus in...

This is some good, interesting information. I'm going to take Ah into consideration instead of just CCA. After all, daily life and longevity is what i'm after. I do like the AGM because of its safer technology. Sealed batteries without the possible leaks and gas output sounds good...

So we have the same boat and you have 27's. I wonder what original equipment was. I can't imagine your previous owner downgraded, so I assume that one of my previous owners upgraded. Only thing is the battery trays look original. Regardless, I have 31's and that's what i'll be going with...

My thoughts exactly. I did see that the cranking amps are up there. That's around what i'm at now but I have 2 different lead acid, unknown age batteries. Also, my starting is an Optima AGM and I don't think that's good for my charger, having different type batteries. I'm going to mull it...

Ok on that link all i see is group 34. I just realized earlier i was looking at wet cell. I thought they were AGM but I keep seeing AGM batteries in both deep cycle and dual purpose. Here's Odyssey. Only Dual on their marine AGM: http://www.odysseybattery.com/marine_battery_specs.aspx

See if this works. Its Duracell's Marine/RV AGM "brochure" http://www.driveduracell.com/assets/duracell/image/1684.pdf

All the brands I've been looking at have both deep cycle and dual purpose AGM batteries. I was trying to avoid buying dual purpose but since i start one engine with my house bank, other posters say I should use dual purpose.
