Heater Fail?

[Soon2BV]

First trip out today, and had water flowing into the engine area.  After some troubleshooting, I believe it was the heater failed, and I had a water flow from there. 

So two questions - how big of a task to replace the heater? 

And, I did a bypass and connected the hose from the top of the block to the connector where the return heater hose was.  Is this a legit bypass?  want to make sure in am not creating an issue.  feels like all did was remove the heater from the loop.  

I will add photos in a minute -

Sorry, is it leaking from the circled areas, or from the heater core that I assume is under your dash??

leak was under the floor, assuming from right in front of driver station, 

the pictures are what I connected - one was to the heater and one side was return. from some other searches it looks like this is the right fix. 

next question is how hard to change this? do I have to disassembly the panel in front of the driver?

I replaced my heater core last year. I did pull the panel in front of the driver which made getting access to everything easier. Hardest part of that was finding all the screws. The biggest challenge in the swap out is just getting your body under the dash area. I am 6' and it was interesting, but I was able to do it. Good luck

Thanks. Parts in order.  I have swivel bucket seats that I have removed before, so I may take the seat out before attempting this.

to bypass you didnt need to take the “to” heater line and connect it to what looks like a wye pioe, you just needed to cap the “to” heater fitting. what happened to the “from” heater hose that should have  been  connected to the wye.  i wondering if your  heater core was already cracked and somebody disconnected a from heater core line from wye.  t

if that is a wye pipe its where the from line  attached to receive a venturi from the impeller pulling fresh water increasing core heat exchange for heat at idle 

though usually wye pipes are copper powder coated black so thats puzzling that its white

the heater was connected, and used last fall.  so either the core is leaking or the line is leaking somewhere in that area. 

I removed the hose from the Y fitting, and cut and connected the "to" hose from the top of the block to the Y.   Now it is basically the same "circuit", just without the heater being part of the loop.

@Soon2BV Where did you find the part numbers and where did you order to fix the heater? I have a 2007 Response LXi. The first time we started the boat this year we had a lot of water showing up under the drivers side dash. My husband helped me disconnect so we've been able to use the boat since then, but now just need to figure out what parts/kit I need to purchase.

Easiest thing is to remove old one and measure it.  Then just go to heater craft or bakes and find replacement by size.

I found a replacement at Bakes. Ordered and should get this week. I bypassed it for now, and will have new hose and a new core when I take everything apart.need to know 2 or 3 outlet and year.
