AA .45 Engine Run in Aeromarine Titan 40 Deep Vee Hull

[Roger Hooks Jr.]

Here is a clip of our AA .45 Engine in our Aeromarine Titan hull. Al Hobbs encourages us not to modify the engines "At All" to demonstrate the engines true out of the box performance. As difficult as that is for us to remain complete stock, this is video of a completely stock AA engine running against modified CMBs. Notice the RPM range and the engine pulls strongly from a crawl at the start to full speed down the straight-away.

The pipe is a MAC Parabolic .45 pipe. I forget the length but I will try to remember to measure it when I get back home. I am a fan of RPM so it is probably as short as I can get it from the back of the engine and still pull a decent prop size and pitch. The prop in the video is am Andy Brown Prather prop, sharpened, balanced and pitched to 3.8". During testing it pulled up to 4.7" pitch on a Prather 245 but bogged in the turns and took the whole straight-away to get up to speed. It was faster though. I figured it was because the boat was old and beat up with a decent amount of body work to get it back to looking nice. The added weight may be taking it's toll.
