when you flip them over backwards, they cut out most of the outside light.

I found several bags of sand in the storage compartment under the bed up front that the previous owner left. I got very excited when I first found the black garbage bags and thought maybe the boat was going to pay for itself but just sand. LOL I left them there because I get some pretty great performance numbers from my boat.

Not sure how I missed this LOL. That's funny. I guess they used the sand bags as counterweight? How many did they use and were they right in the same compartment with the master a/c?

I'll check how many next time I am there. They are in the compartment closer to the bow just ahead of the one that contains the A/C. I never would have known it was there if I didn't change our mattress.

oh, ok. I didn't know there was another compartment and thought that went into the chain locker for the windlass. That seems like an easy way to add some weight up there to offset all the weight in the back of the boat.

Weight is the enemy.

I am aware that under certain conditions, the 460 can have a tendency to run bow high.

If it was my dollar and my boat, I'd avoid the extra weight and see about swapping out the trim tabs for something a bit longer WITH DROP FINS.

I learned this from Tom "TABMAN" McGow (RIP) with Bennett.

I did this on my 10 meter when she still had the gas engines.

Tabman looked at my data at a boat show and showed me the way.

Those tabs "fit" ALL the same attaching points as the factory ones did.

Made a HUGE difference in getting her ass heavy butt up and out of the water and made a big improvement in fuel consumption AND most efficient speed.

Funny thing - on my 450 when we found electrolysis damage quite by accident during a haulout, and needed to replace a tab (unavailable ANYWHERE) I found a pair of tabs that would fit the factory attaching points that were 2 or 3" longer.

As I recall, I shared this here on CSR, likely on the 460 thread (this one)

Can't confirm what effect this had on my 450, as I've since modified the props and added Floscans (swapped out from the 10 meter) but I am getting phenomenal DOCUMENTED speed and economy for my 450 weighing in at 32,000 lbs fully loaded. Couldn't be happier.

Anyway, suggest looking into a tab upgrade vs. adding more weight to pack around.

Just my own experience.

Your results may vary ......

RWS,
Thank you for reminding me and I remember reading your post about the tabs. My 460 definitely runs very bow high and that's with the tabs down all the way. I've often wondered why they didn't use bigger tabs or if all of this is a result of the engines and most of the weight being in the ass end of this boat. it appears through my own research that my 460 isn't much different than a lot of the 460's here and ride very bow high.
 
Got it installed. The doors were a PITA and I am now missing one of the screws with the dow pin on the other side. Anyone know where I can get a replacement?

Also, suggestions on what screws to use to mount it in (size?)

Thank you for all the suggestions. Oh and yes I tested it in the garage before going through all this drama. LOL.

Well my fear has come to reality. I had to relocate due to tornado damage at my marina a few months ago. And I had to move somewhere I knew was very shallow. I’m on a reservoir that raises and lowers to generate power. Today they lowered too much. I’m about 10” out of the water on the starboard side. Sitting on the prop and/or rudder. Don’t think the port side is touching since I can still rock it side to side. So what kind of damage you think I’m in for? Bent prop is all I’m hoping for. Any guess how much weight the rudder will hold? Ughhhh, it’s making me sick to look at it and know I can’t move it
 
What is the bottom like at your Marina? Mud, sand, rocks? My 420 took a squat on the bottom about 6 years ago when 3 days of wind blew all of the water out of the marina. We have a mud bottom. You have to keep in mind that the boat didn't "fall"....it slowly eased into the bottom. Perhaps I was lucky, but I didn't suffer any damage. I did take a bit of extra time at spring commissioning to make sure that the thru-hulls for the mains, generator, and AC cooling water lines were clear.

Can anyone tell me how on the dash, the mid eyebrow panel (not the panel with the gauges but the one that traditionally held the VHF and GPS) comes out, as well as how the radar panel comes out? Neither have exposed fasteners. The gauge panel has exposed fasteners but not the mid brow or radar? I am updating my helm and have purchased a new eyebrow and radar panel for my upgraded electronics but need to figure out how to remove the old ones!

Thanks!
 
My 450 DA was sitting on the bottom (mud) of our canal when the eyewall of CAT 4 Hurricane IAN passed over my home 18 months ago - no issues whatsoever.

I've done this a few times now. Usually there is a piece of rim that snaps off of the screens to expose the mounting screws. Once you you remove the screens you can reach behind and loosen the wingnuts holding the panel on. You may also be able to reach up from the compartment that opens up below.

That panel has maybe 10 machine screws epoxied to the back of the panel. It is held in place by wing nuts with washers. You can access this from the lower panel, by reaching up, but the far port nut is more easily accessed by removing the center panel. It's a challenge the first time you do it.
I've re-done that panel and have the VHF in the center now. Remove the VHF first and then gain access to the wing nuts. A/C vent removals also aid the process.

When you re-did the panel how did you re-attach it? The new panels do not come with the machine screws epoxied to them?
 
I posed this question before and my apologies for asking again as I can't find the the post to the post.

I will be serving my aftercoolers in a couple of week. Obviously the port one on a 460 is easy to get to .
Those Of you that have done it. Could you walk me through the best and easiest way to remove the starboard one.
Thanks for the help.

Well the water came up. I ran it today and all is well. Kind of had to believe. The starboard side sat on a solid bedrock shelf.
