fyi -- I've got a set of 32 pitch 5 blade herrings that might work well in your application -- I used to run them on my28 Apache with 700hp a side... always hooked up real well...

I have the same boat with 630hp each same drives ran 6,000 30 pitch 4 blades 2inch shorties decided to try -3 shorties with 5 blades 30 pitch labbed from blades what a mess! Blowesout ,forces the bow down and lost 3mph and very difficult to drive. The next thing is 1/2 inch spacers than 1 inch and maybe back to 4 blades -2

Rich

Richard great real world info here. Maybe the -3's had a bit to do with it... but yeah I'm not looking to lose speed or driveability that's for sure!

Richard cuny, did you gain anything from the -2 shorties? would you recommend -2 on the 32's?

been debating it, just don't want to have to end up needing to turn 5 blades. everyone tells me -2 shorties on the late model 32;s plane like hell with 4 blades, then some told me they didn't gain any mph

I did gain a bit ran 90 however it handled much better made the boat much lighter and it liked extra weight in the bow.

thats good information to know, i can see how it would handle better running flatter. i was told by a gentlemen with a 32 who installed shorties and gained 2 mph. it seems it can be a critical game of trial and error. every boat responds differently

If the boat responds better with more load, deeper in the water you might want to space the lowers down a bit. -2 shorties don't work in every application
