Top speed of 38
 

What speed can be expected on a 38 lightning with 500 efi's?

525's?

Depends on the year, setup, props, x-dim, etc. A friends '04 with 525s showed 89.5mph on the gps tattletale when he got it. He swapped the props for 5 blades Maximus's and is running around 86 now I think. Some of the newer 38s on the river around here are claiming 90+ with 525s.

90 w/Imco 1" short lowers, stock 32p Bravo props, 525's, 04 38 Lightning

2001, twin step, 500 EFIs

83 mph @ WOT on GPS

I assume all these 38's are side by side motors?

The '04 I was talking about is staggered. When did Fountain stop doing side by side on the 38? Maybe '02 or '03?

200o with 500's, imco lowers side by side 38 lightning

low 80s

My 04' is getting 92mph with Imco 2" shorties 33 maiximus prop,and 525's at 5200rpm. I was getting 88mph out of the stock set up 32 bravo's spinning around 5350rpm. My brother had 01' with 500 efi's and was getting 86mph

87.4 (4 x's on my GPS in dead air and light chop) on stock 500 EFI's, non labbed 26" Hydros, B-1 drives-all stock in a 2001 hull. The engines are basically new though.

74 degrees outside and salt water with 60 gals fuel on board and no one else. They will go faster/slower depending on water and outside temp but I have owned this one for 4 years and it runs faster than ever with the fresh motors. Trim to "5". I can bank on 84-86 on most days. Most "claim" 82-86 according to posts.
