Here is the another one from the same race lookng at the lower unit and prop!

That one is even better! Really shows the abuse the lower unit and the prop goes through. Do you know what props they're running?

That second one is the shot I wanted with the Spectre but never got around to getting. Would have been even cooler in bigger water. Thanks for sharing

I'd bet on herring 5 or 6 blade or dewalds.

How many of you guys run ethynol free fuel? We can only get rec 90 down here. I have been running ACES IV with my motors and it has been good but took a look at the new octane boost from Boostane. Ordered a case to try it. Looks like one quart for 25 gallons raises it from 90 to 94. Will let you know how it works. Also has additives for water etc.

Wish I could run ethanol free. Nearly impossible to find in California other then race gas. Just had my tanks redone because of it.

Double Rigged. I am a former Porsche and motorcycle racer and have investigated a lot of the claimed octane boosters. None, in my opinion really do any real raising octane. If you read the Boostane documentation carefully (and others similarly) you may see that the claimed "points" gain is .1 per unit, not 1.0! So one quart per 25 gallons raises octane 90.0 to 90.4. Just what I found out. ACESIV, from talking to the inventor, helps with upper cylinder lubrication, mostly. Probably a good idea, and DBR recommends it. I think with all their dyno time on 300XS's they know a bit about the good and not so good stuff. Just my opinions. David
