38 Top gun w/Its and spacers
 

Anyone have experience with this set up on ITS and and spacers?
Question is- how much speed loss if any with adding a 1/2" - 1" spacers to get a little more BIte out of the hole?
Thanks!

A lot depends on the beginning x deminsion as I have that set up...Boat originally had TRS drives, when bravos (no its)were installed they were placed in the same location which made them sky high, it took spacers and p5x props to get it to hook up. Later added its and hooked up even better if memory serves me right I think I picked up about 5mph. Every boat is different though

A boat from ct had 1" spacers, I think he lost 2 mph with them in iirc.
