Best props for a 94 top gun, 502 mag efi
What are the best props to run on a straight bottom top gun, full cabin, 502 mag efi, bravo 1 drives.....the boat came with 21p mirage plus. Boat seems to run bow up and needs very little trim.
Cruise around 4000 rpm......48-50 mph WOT around 5000 rpm.......63-65 mph Is this optimal........I just put on 23p mirage last night and ran the boat, don't have alot of running time on these props, I'll keep everyone posted.... Lookin for a little feedback Thanks mark |

wouldn't a 4 blade prop be the best bet?

Your numbers with the 21's look very good for a 502 MAG. THe 23's will lower your rmp's by approx. 200-250 for each inch of pitch. THis will probably give you a little better cruise but will sacrifice top-end.
If the boat carries the nose high get used to it, it's the nature of the beast with the rocker in a Top Gun. You can have the Prop Shop take some cup out of the props to drop the nose some. Seans comment about (4) blade is a good one but watch that you don't sacrifice drive life for more blade area. Remember that the Top Gun is a heavy rig. A.B. |

By the way I'm sure the stuff LEOPAJAM has is premo and probably labbed. This will make comparisons of prop to prop a little harder. Keep us posted....
