took the new new toy out today for the first time since I test drove it in AZ.

picked up some 30p B1's out of the classifieds and ran a 95 on gps, 5000 rpm. First cat and I love it!

what small simple mods can I do with 500 efi's to pick up some speed? boat has extension boxes.

arizona speed & marine makes a kit to bump the 500efi's up a bit

any of the below will work depending on your budget.

hp adds first...
raise x up.....
add prop blades to get the boat to bite when you raise x too high...

nose cones or sportmaster lowers will gain some mph.

me..... I would get the shortest shorties I could find and put them on and start dinging with the props and get it as fast as I could that way FIRST..... Then some winter start modding the engines depending on just how fast you want to go.....because I like to relax at the lake, I don't have a team of guys around to change out extra motors when i pop them..... keep the engines as turn key as you are willing to for speed.

If I am running a 1:50 drive with a 30p @ 5000rpm would I gaing anything out of a 1:36 (mph)?

Im going to put a pair of shorties for this summer. What can I expect from this? 3-4 mph?? or I am I dreaming......

chromecat

at this power, you will slow down by going to 1.36 gears... you don't want to change gears until you need to go higher than 34 props. depending on where your x is now i think you can get 3-4 or more by raising your x...

what's the max hight for the X? the center of my prop shaft is about 1" higher than the bottom the sponson. If I put 2" shorties on that would bring me to 3" higher????? this is new to me....

Thanks
