388 slingshot with shorties
 

anybody running imco's shorties on slingshot need some info thinking about changing from standard lenght imco's

I tried to run -2 but boat didn't want to plane and had to go to inch and a half spacers to get it on plane but looking back think I should have played around with some different props first. I was trying to run 32p five blade herrings and think I was changing one too many things at once to really know. I have been thinking about experimenting again this time one thing at a time

talk to brett at bblades helped me alot and he knows how to set the slingshots up hes done several of them

This boat runs great. http://www.offshoreonly.com/classifi...o46110-en.html

I know Charlie who has/had Nauti-Girl at LOTO tried them once and ended up taking them off. Stock HP500 boat with PR cabin.

is that sportmaster lowers?

Yes. The boat runs solid.

A friend of mine bought that boat new. The engines were set 2" lower because he thought that he would put intercoolers and other changes later down the road and he still wanted the engines to clear the hatch. As a result, the X Dimension is 2" lower than a standard slingshot. So, with -2" shorties, it has the same overall propshaft centerline as any other slingshot.

I like the thinking ahead. It's a sweet boat. I can't wait to tell the current owner.

I spent a lot of time boating with him in that boat. I could just see everyone thinking that 2" shorties are the way to go based on how well that boat runs (used to run 90+ in the heat with 4 peeps any day of the week.) Not realizing that it has a different transom cutout. 2" shorties do not work on that boat with the standard x dimension cutout.
