Shower add-on for old restoration

[Canuck-Surfer]

Quick question here guys...
What shower kits for adding a hot water nozzle to an old boat do you recommend. I have searched online with not much success. I am restoring my 96 Sport and would like to add this to the project list.

Also...I have a separate thread about my 96 Sport Restoration (https://www.planetnautique.com/vb5/f...ration-project). Should I keep all of my questions embedded in that thread or start specific questions separately?

Heatercraft sells a good kit.

Thank! Just looked at their site. Their kit includes the mixing valve, shower parts and pump. It does not appear to have a heat exchanger. From what I understand I need a heat exchanger to have exhaust free water coming out of shower correct? Educate me on water cooling path if I’m wrong here.

I've been reading more about this and I see that there is both options with Heat Exchanger and without. Without a HEX, the issue is the water can sometimes be rusty. I need more of the pros and cons. And how many pumps do you need. If you go with the HEX option, then you need 1 pump for the raw water into the HEX that ends up becoming the hot shower water into the mixing valve. I am guessing you would need another pump for the cold lake water going into the mixing valve as well?

How have you guys designed this for a boat that didn't have it from the factory?

Lastly, I've already got a massive stainless heat exchanger I got years ago for a hottub project but never used. Pics to follow.

Most just pull the hot water out of the block either by putting a fitting on a drain plug, or by teeing off the heater line if equipped.

Correct, my 2004 SN 196 LE has a shower and it’s plumbed to use hot water directly from the block. It is then mixed with cold water from the lake depending on the amount of flow through the mixer valve. It mostly leave mine 90% hot water. Great for preheating wetsuits, gloves and boots. Likewise awesome for showering off on swim platform after a brisk ski run.
