Hot water shower install

I'm adding a hot water shower to my 2000 Supra Launch and was wondering where the best place is to tap into for the hot and cold water supply.

For the cold water supply is it necessary to tee after the raw water pump or can I just tee in right after the pickup?

For the hot water I have 2 options remove a engine block drain or tee into the hose that connects between the rear of the exhaust manifolds?

you could use the water pickup for cold. drain plug for hot.

Are you using a shower kit or setting up your own?

I'd use the block drain for hot.

2nd the block drain. I have an 01 launch, that's where mine's at. see link below for DIY.

Thanks

What size is the hose is the raw water intake? and what size is the engine block plugs?
Boat is up at the lake so I can't measure.

Matt, if you have clogging issues when using the drain block, Tee off the heater hose coming from the intake. This puts gravity on your side.

I have installed a shower on my boat and was constantly getting clogs until I relocated the hot to the intake side. It did not effect my heater and the shower has yet to get clogged.

Just did mine for about $100 dollars.

Sorry I didn't answer your question. The drain plug is a standard NPT 1/4" thread plug. I used all 3/8" hoses. I used a 1" pipe nipple with and tapped a 1/4" hole into it to tie into the water hose on the discharge of the impeller.
