40 Ft Fountain First Splash
Just finished installing my new 700 HP Blown 502's. Here's the first test run. What do you think?

It ran very good, up on plane quickly, 68 MPH on the GPS at 3500 RPM. Then a problem, Port motor pulled up to 5200 RPM but the Starboard motor pulled up to 5000 and then lost power. They pulled 698 HP and 689 HP at 5500 on the dyno with no problems. After some testing back at the shop we discovered two problems with the Starboard motor. One is fuel starvation, were're checking the filter, maybe cripped hose, stuck check valve, etc. The other problem is the blower sucked the choke closed, we had them wired open on the dyno. As soon as we get these problems corrected we will splash again. Hopefully this weekend. I will let you know how it goes.
