Weird. The top of that bulkhead shouldn't be exposed. But... it WILL be softer further down - it just isn't as apparent. Gravity works :) The fix is to cutoff the white skin, replace the core, then glass the skin back on and add some tabbing. Or just start fresh with new glass and skip...

It's not clear if you inspected when out of the water or not... or just a looksie from the topside?

It sounds like you may have installed the 2nd charging lead from the motor incorrectly. The charging leads should either go directly to the batteries or be piggybacked on the posts on the back side of the battery switch to the #1 and #2 posts. If you can, it's preferable to go direct to the...

There's no question that AGM's are superior to regular LA in terms of vibration resistance, being better at supplying consistent voltage and longevity. That's well documented and proven. Those are facts. As we talked about a couple times, though, whether that's worth it to an end user when...

No worries, Chinookie! Everyone starts somewhere with their "knowledge base"! As you're starting to figure out, it's a little confusing because there are multiple theories on the best way to use two batteries. And it really boils down to how they are set up for charging (one or two charging...

To expand on this for Chinookie - the reason for this stems primarily on preserving battery life (in years) as long as possible. Yes, different types/model/age CAN be safely combined - but lifespan may be affected.

But... to better state the answer to your question... connecting two 12V in parallel (even with different V) is done ALL the time and for MANY years. I'll take history's and personal experience's answer over internet stuff any day of the week! :)

I don't see any info in the reddit thing. Skunk is not talking about it being a problem - just a waste of time given he has other means that work better for him.

I'm not sure where that info came from about (2) 12V batteries of unequal voltage creating a fire if connected together in parallel. I suspect you either misinterpreted what you read or that what you read is simple internet gossip/lore. If you're still unsure, copy and paste what you read.

Correct, it wouldn't be from a thru-hull ducer. Can you take a few pics and share them? It's hard to visualize how much you are talking about and whether or not it's normal. In the meantime, if you're sure it's from the tab, inspect it really close. There could be something snagged on it...

Oh, good. I'm glad to hear that you at least have a box. It could be that it's the box/fittings that are leaking? Maybe try just filling it up while observing it - if you haven't already done so, of course. I can appreciate the want of a dry bilge!

Kind of a side point/question here... MG, are you saying that the AC drain pan is plumbed directly to the bilge? I'm surprised that Grady does that instead of running it to a small, sealed sump box that then pumps directly overboard. Some other boat brands do that. Often the shower drain and...

I wanted to clarify something regarding my last sentence in Post #2. A better way (clearer) to say what I did is that it's not "required" to let the core cure and THEN put the 1708 on - it depends largely on how confident you are that the core is in full contact with the hatch and will stay...

I didn't watch the video, but AGM's require MORE voltage. I don't know the charging ability/specs of the older 2-stroke charging system... but logically :) if it's good for regular LA, then it must be a lower charge rate? I always thought the 2-stroke charging system was not as adequate at...

It wouldn't hurt (other than cost and added weight) to use 1708 between the core and the hatch - but it's truly not needed. I can understand that someone new to this type of thing would think the opposite - but it really isn't needed. The strength of a hatch is not so much from the thickness...

AGM's are nice - they resist vibration better and generally last longer than regular flooded batteries. But of course this comes at a cost and only the buyer can determine if it's worth it. SOME newer engines require AGM's because of the stability of the battery and because they can power more...

The reason for the layer of glass between the core and the hatch is primarily because this is a "new" build and the entire hatch isn't beign done all at the same time. It's to take up any irregularities between the hatch and the core. Lightweight mat is all you really need. You don't need...

Yeah, it all comes down to how items are initially installed and/or the dreaded soft-core issues that have seemed to plague GW's for a while, now. I consistently lift boats much heavier than a 225 with no issues - so the eyes can handle it... it's the other variables that let us down :)

Oh, good! Suggestion... use a pipe cleaner and saturate the core with epoxy or poly - keep going till it no longer absorbs in. Ideally, drill the hole out about a 3/8" oversize, fill with epoxy/poly, then re-drill. But the pipe cleaner method is a pretty good option.

Ah, gotcha. You want to match that "shoulder". While you have it out... how's the transom core in that area?
