shorties on a bullet ????
 

I have an 89 bullet with a notched transom. It has xr drives on it. I feel like im dragging alot of drive. I leveled the boat on the trailer then i trimmed the drives to make them level. I measured straight out from the nose cone to the bottom of the boat and i got 5" between the center of the shaft and the bottom of the boat. I think i can run shorties any buddy out there with some experiance that can help me. How much prop should be in the water ? Were should my drive shafts be compaired to the bottom of my boat. I wanna no if its even worth my time an money. Any other options besides running shorties ? Any help would be appreciated !!!

My buddy ran your boat with you. To be honest there are a few people around our area to help you. PM me and I'll try to help...

Your PM box is full.....A couple guys tried them with pretty good results. You give up a little rough water but gain a little speed. Spinning in is faster to but, i thought the handling sucked on mine.
As big and heavy as these bullets are {8900lbs dry} They will
never be rockets on a pond but...They will run with the 38s when it's snotty:drink:

How was it getting on plane? I bought a pair of imco -2 shorties for my bullet, but haven't even tried them. I am presently running stock 454 mags but picked up a pair of Hawk 525sc takeoffs. I think the blowers should get me close to 80 ( with a bob madara cam also) so may not even bother with the shorties. Were the handling issues that bad? Mine bullet has no notch.

Hello
 

My boat gets on plane awesome !! Thats why im thinking i can go up with drives. I have a notched transom on mine. I have 575 sci in the boat with xr drives. I hit 81 this morning on gps with my new props. I just think theres more left. It really feels like im draging the drives and i guess i wont no different until i try them. Are you thinking about getting rid of your imcos ??? thats what i was looking for. so if your interested let me no.

I turned mine "In" for about 15 minutes then, pulled it and switched back...I thought it really screwed up the feel of the boat. Others have done it and got used to it I guess.
Try it..It's easy to do

A couple guys tried the Imcos and were happy...I never got around to trying them. I was very happy with how mine ran as it was.

Wouldnt mind pickin up a couple mile an hour myself over the winter. Im curious about the shorties too! Put those bad boys on and lets git this party started! A bunch of 85 MPH Bullets would be cool...:ernaehrung004:

KReed go back and re read this post. "You give up a little rough water but gain speed" That's fine if you stay on the river but in the ocean I don't see it as a benefit. How about boxes on these boats???? Let it ride like a longer boat no? It seems that both rough water handling and speed can be achieved.

wouldnt putting boxes on put the drives lower in the water ? would you have to put boxes and shorties on to achieve the goal of gaining speed ?

Yaaa
 

I like your thinking Kreed !!!!! :evilb:

Yes the boxes will put the drive back 12" and down further but you can and would probably have to to go up like 3" but you would be running in cleaner water and be able to go up in pop pitch resulting in more mph. IMO running just shorties no boxes has those props closer to the surface which in chop or bigger water will result in cavitation equaling a loss of mph. Boxes and shorties work real well in some situations and not so well in others, I think there is a little voodoo there....some trial and error.

Natlee if speed is what you are after get the Arizona speed updates for those motors I believe they make them 625hp. Someone can chime in here but I think it has a smaller pulley and a ecm update.

I spent an hr taking to az speed the other day. The kit your talkin about comes with a smaller pulley takin it to 6 lbs, msd ign., cooler thermostat, and reprogram the computers. Its a $1,000 a side with a gain of 80 hp a side !! I'm just nervous about bumpin up the boost. I'm guessing merc put them were there at for a reason. Or I could just go buy a cat and quit messin around !!! :)

2K is cheap for that HP gain !!! Go for it!

I know lots of people that have turned them up with good results I would go for it if it were mine.

HI Wayne, are your imco's available for sale?

Sorry, long gone.

thanks anyway

Still looking for some -2 or -3 Imco shorties for B1...
