30 pitch four blade spinning the motor in the 6,000 to 6,200 RPM range. The five blade prop is not quite as fast on the top end but is more efficient producing much less slip running under 4,500 RPM. In fact, running 3,000 RPM the 30 pitch 5 blade is about 7 to 10 MPH faster than the 30 pitch four blade at the same 3,000 RPM. SVO 540 states the only problem with the five blade is the boat goes too fast idling through the channel and he either has to drop it in and out of gear or just make the pass. The motor has a low 750 in gear RPM idle too. The five blade is the main propeller on El Diablo which is what we were running this day.
El Diablo is 13 years old and looks brand new. It is in perfect condition. To keep EL Diablo in perfect running condition SVO 540 has had GT Performance rebuilt the motor once, had the interior reupholstered once and the gel coat color sanded once.
El Diablo spends the majority of its time on Lake Havasu running between Havasu Springs and Pirate's. Most of the time El Diablo is cruising around the lake at 40ish MPH which is in the low 2,000 RPM range. But when it’s time to go, hold on.
El Diablo goes to bed each night on an Extreme triple axle trailer.
