Remember Triple Digits boat ???????
Test 20
I need to figure out how to take some of the chime walk out of the boat and the torque steer. I added a torque tab to the lower skeg on the drive and I lowered my seats by 2 inches. by lowering my seats it lowers the CG in the boat witch helped the chime walk. I also took some power out of the engine. My peak power on the dyno was at 33 degrees of timing. I turned it back to 31 degrees of total timing. Went to Iong Island with some friends and the adjustments worked, I went the best of 98.7 mph (Natural Aspirated). I improved 2.7 mph. The boat handle the best ever in 3 years and was super easy to drive. I don't feel the boat had any more in it. For this combination to go any faster a major change would be needed. As crazy as it sounds I'm starting to think I built the wrong engine combo. I actually have to much torque and the power range is incorrect for such a small boat and the big speed I'm looking to run. Look around on the Internet boat chat rooms and there are plenty of over powered 18 to 24 foot V bottoms and they all go basically the same speed with in 10 mph of each other. There in the 80 to 90 mph range. Some of these guys have huge HP and Torque and in reality they should be running more like 110 mph. This is why it didn't matter if I had 4 people in the boat and full tank of gas or no people in the boat, it went all the same speed. Same thing with the props, I could run a 22 pitch or a 30 pitch and it still went the same speed just different rpm. I will test this by installing another engine that has less torque.
Do you remember this guy ??????? with all the bs about going over 100 mph . www.rlcpe.com
