'02 SANTE Heater Installation Photo Chronicle

Step Twenty-Two: Tape Hetaer hose to copper wire, and pull from engine to dash. I chose to go this direction because it aloowed the hose to be laid out in a much more straight path, and would the bind up a little less. This part is tough, but it can be done, just go an inch at a time. Eventually the hose will be from the back to the front. I also chose to double up the hose and pull it all at once. Note the engine end has not been cut, so it is still one long piece of heater hose.

It was at this time that my suspicion that I did not have enough heater hose was confirmed. See the photo of the heater hose by the V-Drive. There is no way it will make it to the back of the boat, let alone the other side of the engine. This was solved by adding a valve in the supply line and splicing an extension to the return line. added the valve so that I could control the hot water. I live in Texas, so we don't need any more heat in the dash area during the summer. Even with the fan turned off there will still be hot engine water flowing through the heater core. With the valve, I can turn this water off, and not worry about my feet getting warmer than usual. More on this latter.

Step Twenty-Three: Connect heater hoses to heater under dash.

Step Twenty-Four: Install supply barb in engine for hose connection. I decided to connect my hoses in the same manner that Flyerace did his. (See his post on his heater install.) I connected the supply hose barb to the port on the intake manifold, and the return hose barb to the port on the water pump.

The allen plug is where I tapped for the supply water. The allen wrench size is 3/8"

Step Twenty-Five: Install return line hose barb. This barb is installed into the waterpump. The plug on this one was a 9/16" square plug.

Step Twenty-Six: Connect supply heater hose to engine hose barb. Since I did not have enough hose to reach the final desination i cut the supply line at the rear of the fuel tank. I was hoping this would leave me enough hose to make the connection on the return line without an additional splice. It also allowed me to add the valve in a reasonably accessable location. After assembling the valve (not supplied in heater kit) I attached it to the hose extension and the supply line to the heater unit. I then routed it under and to the rear of the engine, carefully noting any items it must stay clear of (rudder and stuffing box). Then I routed up the engine staying clear of the accessory drive belts and pullies, finally connecting it to the supply hose barb.

Step Twenty-Seven: Connect return line hose. I routed the return line in a similar fashion to the supply line as they go to locations that are close to each other on the engine. Unfortunatly, I was about 2' short on hose length. I added a splice using a brass splice and hose calmps (not supplied in kit) at about the raw water pump. Then I routed the hose up the engine away from the accessory drive, and to the hose barb securing it with a hose clamp.

Now I need to use some nylon zip ties to secure the heater hose in safe locations.

After that, it is wiring and installing vents.

Also reassembling the boat :mrgreen:

Here are some interior cabin shots so you can get an idea of access and routing.

One more comment. I was able to fish the heater tube, next to the gas tank, far enough to grab it from the ballast tank compartment. Then from there feed it up the the hole under the steering wheel. All without pulling up the engine compartment, or the seats and without a fish wire. For anyone trying to do the install, I would suggest trying it like that first. It will save you a lot of time and trouble if successful. It may seem crazy to be doing all this in the summer, but worth it later. I'm actually thinking about adding a second heater to the back of the boat for all the passengers to use.

Great write up Ag. Beginning to end, how long did the install take?

[skinautique]

Is it just me or did you take a ton of unnecessary steps? Why did you bother to cut out the chunk of fiberglass behind the kick panel?
