BlackJack/250 SHO High Performance Prop?

And if it matters at all, I forgot to mention that even at 1/2 to 3/4 tank of fuel, still running 62-63 with 1 person in the boat.

The only guys I know getting 67-68 are running the Bravo 1 XS 26. One running 250 E-tec, the other 250 PRO XS. The Bravo 1 XS has thin blades, not very durable. Run it through a reef, sand, or mud once or twice and loose couple mph. And not just anybody can fix them..

My thoughts on this subject,
Why my boat isnt performing like his. If I had the same boat that u have, boat motor prop fuel etc. My question is, would my boat performance numbers be better, being that i weight 170lbs and the other person may way 230? A Boat performance is based on weight right? Imo i think thats y the performance number are different. Correct me if in wrong. This is something id like to know The weight of the person in the other boat is what we dont know? could this be y performance numbers are different? Does he weight more r less than me. sent from my iphone slayer Galaxy NOTE II |

It is possible to gain the speed with a bravo but holeshot will suffer....like stated before bravo is not a fishing prop,it is mainly for speed. Tweak the blades and it will be very hard to get it right again. That yamaha saltwater series is the best prop for a bay boat,the wide blades are designed to carry the weight of a bay or offshore boat. Take the trolling batteries and motor off if you want to gain speed.

1. What is the max rpm on your SHO
2 What is your gear ratio It may be possible to get more from a more efficient prop but you must know what your current slip numbers are . Factors that effect speed are hull design , weight, prop , setup and air temp. |

Max RPM on the SHO is 6000-6100. I'm spinning 6100 at 63 mph. Gear ratio is 1.75-:1. Dry hull weight is 1950 lbs and motor is 505 lbs. My prop seems pretty efficient and I'm just starting to think the people who are claiming to run faster with the same setup are slightly stretching the truth. I talked to Kyle at LAM today and he even talked to Bill Kenner about it. Neither of them have heard of a BJ/250 SHO running over 63, so that may be question answered right there. I'd still be interested in running a bravo 1 XS just to see what it does tho...

Did they mention what conditions were when those numbers were achieved? My boat would run about 2mph faster with a slight chop.

Maybe alittle wax on that pretty black hull?

Haha it stays waxed. I guess I'm not putting enough to make a 5-6 mph difference though

Nope. But I'm assuming it was a hurricane force tailwind with a very strong following tide....

As a BlackJack owner, I also claim BS on those making such claims.

I have a Bravo 1XS, now this on a completely different hull so this is apples to oranges but it runs 14% slip on my boat. Now I do have another prop that runs 7% slip but it aint cheap. The guys posting may be fudging some on their numbers. BUT You should do this just to see..... because I bet their numbers are with 1 battery, no trolling motor, 5 gallons of gas, on a 40 degree morning. (important) Go do this and see what it does..... Then let us know. |
