1996 1 Step Lighting What Speeds
I HAVE 1996 1 STEP LIGHTING W/ 502'S HYDO'S 27 PITCH 4 BLADES RUNNING 4600 RPMS AND SEEING 63 TO 64 GPS. I TRIM IT UP TO 4 TO 5 ON INDICATORS AND NO TAB.
I HAVE HEARD IN THE 80'S I AM YET TO SEE IT.

A VERY STABLE BOAT HAVE TO USE SOME TAB TO MAKE RUN LEVEL IN THE 3000 TO 4000 RPM RANGE. RUNS RIGHT OVER 3 FOOT WAVE IN THE 4400 TO 4600.

WHAT SPEEDS ARE YOU ALL SEEING AND HOW DID YOU GET THERE. WHERE ARE TABS AND TRIM? WHAT PROP?

What size Lightning? A friend had a '95 35 with 502's and he was seeing mid 70's. You should definately be running faster than 63.

35 38 42 ? what size?

Wow thats odd. I have a 32 without a step w/540s and 27 hydros. Im having fuel pressure problems, but @ 4300rpms, Im at 74-76mph

sorry it a 35 lighting

22 % Prop Slip To Get This #

lab the props get the rpm up.. i ran i think 28 hydros labbed on our non step 35 with 502's prob around 550 hp i had it set up to spin 5150 - 5200 at just over 80.

99 35 lightning single step w/ 502 magnums (efi) spinning 23p Mirage Plus' through 1.36 Bravo 1s. I see 5100 rpm and 78-79. I have twice seen 80.3 with very light fuel and passengers.

4000 RPM equals 60 mph and 30 gph total, almost irrespective of the fuel and passenger load.

Tab and drive settings vary based upon the conditions and "heartiness" of the passengers.

Fountain will fax you the speed report on your boat. Give them hull ID and you should be upper 70's at minimum. 62-63 something is severely wrong. My 1993 35 non step does 75 502's carb.

1997 29' Fever single 525SC 77mph 5100 rpm
