Powerwashed the boat for the first time today! I didn't want to inject any more water into it until all holes were plugged and I got in a new drain pipe. Foam is replaced and buttoned up the deck, so she's watertight (topsides at least!)

Phase 2: drain pipe repair
The drain pipe from the drainwell to the transom was gone. There was nothing in there but foam. I glassed in two pipes, one inside the other, from the drainwell to the transom. I'm pleased with it.

As the hull is taking shape, I've been thinking of how to set up the motor. I'm planning on mounting the battery in a box over the drainwell, installing a 7 1/2 gal. tank on either side of it, and a fuel/water filter somewhere on the inside of the transom. I also plan on building a seat to go over all this.

My question is when you're running two tanks, do you use a quick-disconnect at the tank end, and switch it when you run out of fuel, or do you put in a Y-valve of some sort?

I just had a quick disconnect to change from tank to tank.
Both of my 12 gallon tanks were located under the Reversible Pilot Seat on my Montauk...

Many, many, many photos of parts are located in the OEM Parts Photo section.
Take a look:

In the above link you will find a 12 Gallon Temp Tank that many people use in place of the older 12 gallon metal tanks. Moeller makes a 12 gallon tank also.

I also have two 6.6 gal. tanks. Will the larger tanks fit under the pilot seat?

jddar,

It depends on the year of Montauk you have. Some of the earlier Montauks had some wood blocks underneath the seat that held the pivot rods in place. The later Montauks did not have these wood blocks.

In either case, I would still raise the RPS 2 inches (or more if a person is taller than 6 feet). This will allow the gas tanks to fit easily under the seat and also provide a more comfortable seating height.

I used a full 2 inch thick piece of teak and shaped it like the bottom of the RPS Z Legs....
It is very easy to do. You don't have to shape it to the Z legs if you don't want to but I think it looks a little better.

jddar,

You could use starboard on the newer models instead of the teak to raise the RPS...
