Hello to all. Great Forum with lots of activity. I am new and hope to help where I can.
I purchased my 2767 a year ago and have replaced canvas and upholsery and am presently considering upgrades to the interior next. The boat has a hatch air conditioner and I would like to replace it with "central" air and heat. I have the following questions:
1. What size BTU did Carver install and was it adequate?
2. Where did Carver locate the AC unit? Currently, my water heater is under the dinette and I could move it foward under the V-berth, but would also like to put a waste holding tank under the V-berth.
3. How many AC ducts and where were the ducts located?
4. What size ducts - 4 or 6 inch diameter?

I have a Sealand Traveler head (a way too small 5 gallon holding tank located directly below the bowl).
1. What size waste holding tank did Carver use and where was it located?

The boat has twin 6 cylinders (431a) with Volvo Duoprop outdrives. My wide open throttle is around 4800 RPM with Volvo B5 props. My concern is that I need about 3500 RPM to stay on plane, sometimes 3800 RPM depending on wind and waves.(about 22-23 MPH per mt GPS) They are brand new Volvo props. The originals spun the hubs earlier this summer and no one I have found will replace the hubs.
1. Is this the acceptable RPM and plane speed for this boat?

Thanks ahead of time for any and all input or respones.

Mark, welcome to the best forum on the forum! I have an '89 Santego and I think I may be able to help.
My aftermarket A/C is a 12500 btu and works well. Temps in the 90's with all the shades closed and limited in and out will keep the cabin in the low to mid 70's
The a/c unit is located under the v-berth, directly under the access panel.
6" duct work - one round 6" duct located port and a traditional rectangle stbd - these are mounted on the "shelf area" in front of the mirrored bulkhead dividing the cabin from the v-berth (does this make sense?) The return is midline under the dinette.
I am pretty sure your holding tank is 9 gallons because I have the same set-up, but I agree - way to small, but one way to "extend" the usage is fill up a cup from the head sink and use it to rinse and flush instead of pumping water through the head itself.
You don't mention if you have gen-set, if not, you can squeeze and I mean squeeze a 4.5kw in the engine compartment and relocate your batteries in the stern rod-holder compartment.
Regarding your rpm's and staying on plane, I have twin 4.3L Mercs (190 hp each) with Alpha 1 drives and I have to turn about 4200 -4400 rpm to get on plane and hold at 3400 - 3800 to stay on plane. Just like you, it depends on wind, weight, etc. My GPS shows 22 - 26 mph at these rpms.
Acceptable rpm's? Don't know - my gut is the v6 engines are just a little underpowered for the boat, 8400# dry, over 10k loaded out.
 
MarkZ,

I am in Sandusky as well. My boat is docked on Kelleys Island. I have a 28 Mariner and I installed a 16k BTU unit I purchased new off of ebay last year. If you are ever on the island, and I have not sold my boat, I would be happy to show you how I installed it. I know we have different boats, but the fundamentals are the same.

Thanks,

Jim
