I'm working with the Yamaha guys to get my rig dialed in right now, unfortunately I haven't been able to spend much time in FL. so I haven't gotten much done. They cured the overheat problem with the new ( redesigned ) intake grates. I couldn't believe that the minor change in a $2 piece of plastic could be responsible for taking us from 2-4 lbs. of water pressure to 12 lbs. at 65mph, man you never stop learning ! I'm running labbed 4 blade 26" Bravos 72.6mph at 5800 rpm turning them in. We're gonna swap the lowers and try them out to see what happens. I love the motors but the Yamaha guys know nothing about going fast, but they're learning. They've been great about working with me, the performance market is so small that they have yet to really look at it. The powerhead is awsome but the lower unit is lacking for speeds in excess of 70mph. I wanted to be able to cruise at 65mph on 87 octane without alot of noise or worry, I got that. I'll keep ya posted.
All of the pics of my boat came out fuzzy, here's one.
