I'm going to stick with 25% nitro for the .91. It will be sucking down the fuel as is. The fuel tanks for a 44" Seaducer are a 4 oz. hopper and a 24 oz. main tank. [X(]

Here is the .91 ducted fan engine completely converted to a front exhaust marine engine. All ready to go into the Seaducer. The header is a MAC 15 degree header, glad I found it on their website. I was almost going to make a custom one. The one included with the ducted fan engine is a zero degree and is real short. The length in the picture is cut down to give a starting pipe length of 12.5".

Looking good, Craig. Now you can go out and kick some CMB tail! Is the Seaducer set up, yet?

Seeing that picture reminds me that those bosses on the case next to the exhaust header were drilled through and tapped for cooling water nipples.

Thanks. Not done with the Seaducer yet, but shouldn't take long. We have 3"-6" of snow forecasted for tomorrow, so spring is NOT here yet. []

Yah, I couldn't decided whether to drill those bosses for water cooling. I got nervous about messing up the case and decided not to bother. Most modern marine engines don't have cooling there anyways...

You could add a cooling coil around your header if you feel more cooling is needed.

Blackout

Yup, good idea! It also would be a good way to preheat the cooling water during the colder months.

Have you done any mods on that engine. Yet???

Blackout

Not going to at this time. I want to run it stock first to get a baseline.
