Props
In todays world props have come a long way since some of the posts I’ve read on here with Cafe Racers and props….. if you were to prop this boat with todays tech. She has bravos now unsure of gear ratio right now but guesstimating around 485-500 horse per side naturally aspirated engines stainless marine exhaust dart intakes Holley double pumpers….. has some old 21p 3 blades on it right now prior to these new engines….. is bravo just the prop of all props now? School me…

We’ll if start with 4 blade b1 24s. My topgun with konrads was running 4 blade 30s had 575 sci engines boat ran 78 with those I went to 5 blade 28s boat went 79 and cruise went up 8 mph. I’m not sure of your x if you swing 5 blades and the bravo might not like that I’d stick with 4 blade bravo props they seem to work well on the old straight bottom boats

I don't know about schooling you, but the Bravo 1 four blade is a great all around prop for bigger twin engine performance style hulls. When running a 30Ft + heavy Cigarette boat, the four the blade really helps the boat to get on plane quicker than a three blade prop. You will have a higher, more stable cruising speed and better throttle response over a three blade prop. A 4 blade Bravo1 prop does pretty much everything better than a 3 blade for a Cigarette boat, except for top speed numbers. You will usually lose a couple MPH at WOT when u go from 3 to 4 blade props. Not always, but usually, just because you are now pushing more water with the extra blade, slows the boat down a touch. But in my worthless opinion, I think the 4 blade is a much better choice for all around performance than a 3 blade propeller.

I should have mentioned that they are sportmasters! Sorry bout that! I’ll check the depth tomorrow cause I’m curious myself about it. Hopefully if things go right and weather cooperates might get the hull wet tomorrow and check everything out! Fingers crossed
