Heater Install in 2006 LSV
I am in the process of installing a Heater Craft three outlet heater in my boat so I thought I would post up some progress pics. I bought the complete kit including three extendable heater tubes from go2marine.com for $396 + shipping. Many thanks to csmsk (Chris) whose detailed install post inspired me to tackle this project.
Most installs I have seen that incorporate shutoff valves have a short length of hose between the engine and the shut off valve. The obvious issue here is if that hose leaks, the shut off valve won't do any good since the hose is before the valve. So I decided to install a series of brass fittings (all from Home Depot and Lowes) from the block to the shut off valve, both at the supply and the return. This way, if I get a leak anywhere in the hose, I just shut off both valves and I'm good. I can finish out the day and fix it when I get home. Below are the pics:
This is the supply line. There used to be just an allen head plug here. I used pipe joint compound at all the threaded joints.
This is the return line. It's tight but it clears the recirc pump hose. There used to be just a square head plug here.
This is the heater core mounted on the front of the footbox and electrical wiring wired to a spare switch on the dash. You can see the 2" hole on the left thru which the heater hose will be routed. I drilled the hole fairly high so that if I take a bunch of water over the bow, hopefully, it won't make it into the footbox. I can't come up thru the existing hole in the top of the footbox because when my sub enclosure is in place, there is no room for the two hoses. It was a royal pain to install this heater core because of the cramped space you have to work in.
That's as far as I've gotten. Will be removing the floor next and run the heater hoses from the engine to the core. Then the fun part - drilling three 4" diameter holes in the gelcoat for the heat tubesAl

Thanks for the encouragement, guys.
Moombadaze, that is the PerfectPass servo unit in pic 1. Don't you love how they installed it? Just hose-clamped it to a hose? Oh well, I guess it works.
Tonight, I installed the heater hoses from the engine to the heater core.
Ever wonder what it looks like under the floor of your LSV? Well, here you go. There are two panels, and 4 screws per panel. Remove the screws and pull up the panels and this is what you see. I don't think it's necessary to pull it out but I did just to make it easy to run the hoses.
Here's a pic of the shutoff valves at the block with the hoses attached.

Pic of hose routing on the port side of the engine. I zip tied the heater hoses to the ballast hoses.
Pic of the heater core with hoses attached. It doesn't matter which hose you attach to which fitting. The 2" hole in the footbox for the hoses was little tight. I should have drilled a little bigger hole.
Ready for flex duct. Pic of the three heater core outlets from the front side.
Tomorrow is the big day - break out the 4" hole saw and do some damage!Al

Looks like it's coming along just great, Al! I absolutly agree that mounting the main unit was a pain in the arse. I also like what you did with the valves. Hope you have as much fun as I did with the hole saw!
Did you notice that there's always water in the cyllindrical hole in the gas tank? What's up with that?We are eternal, all this pain is an illusion.

Wow, a 4" hole saw creates a lot of dust! Last night, I drilled three 4" holes and installed the pull out tubes.
Here's the two holes for the vents in the walk thru area which is the factory location. I put two layers of masking tape on the gelcoat and measured about ten times before finally drilling. I ran the 4" hole saw in reverse all the way thru. As you can see, it makes a perfectly clean hole - the chip in the bottom of the left 4" hole was caused by a protruding head screw in the pull out tube body which I caught on the edge of the hole after test fitting the tube then pulling it out. The chip in the rightmost screw hole was because I tried to put the screw in before chamfering the hole - doh!. It all gets covered up anyway.
Here are the tubes installed. These are the new style vents - the nice thing about them is that you can twist the vents to open and close them.

Next, I drilled the hole for the third hot tube which I put behind the driver's seat.
Nice clean hole.
Here you can see the hot tube in place with the flex duct connected and secured with mountable zip ties. I ran the flex duct in the gunwale, behind the trim panel and above the floor. One of my goals was to still be able to use and access the space under the seat base for storage and you can see that I can still do that.
Here's a pic with my junk back under the seat base - I keep my collapsible oars, first aid kit, scuba knife and goggles, tools, etc. - stuff I don't use very often - under there.
