Excellent Sir!

Glad to see you’re doing another school build.

Sorry for the delay. In the spring of last year we got finished late and could not get the cage and engine stand in right away to be powder coated. EK Machine in Fall River wisconsin has helped us out the last couple of builds and did not let us down this time, they just had to wait till they had some down time to squeeze us in. We primed and painted the hull at school and then hooked up with John Hagen in Onalaska, WI to put poly on with the help of Mike Moeller, Ira Buck ,Mark Smith, and myself. It really turned out nice.

We picked up some nice rudders from Jake Tupper at Gale Marine in Galesville, WI and then managed to get them painted along with our fuel cell. The last thing we got done before the summer break was a floor board got put in.

Sniper
It is a 2.5, 165 HP fuel injected subaru.
The engine was set-up with two cooling radiators and a swirl pot right out of an airplane. With the prop pushing air in the other direction they would not cool the engine down where we wanted the temperature to be. We tried cooling fans and it was better but not great. Then we found a crack in the swirl pot, so we put in a bigger radiator and got rid of the two small ones. Added an expansion tank and we were in business.
