How much HP do I need to go 150 in my 36 nortech cat???

1100's
1075's

You may be able to get there a little easier than the other 36's. Your boat has no cabin, right? Give me a shout when you have a chance. I have pre-owned 1150 Nor-tech's, pre-owned Mercury 1075's and pre-owned Mercury 850's in stock. Any of those packages would really wake up your set-up for next summer.

Later,

Peter

how quickly do you want to get there?

NOW! LOL

Well then get yourself some 1200's with 5.0 whipples a set of big herrings and then "Hammer down and lets them puppies eat" !! Hey it works for me !!

What gear ratio,pitch,rpm and speed???

Gears ratios are 1.29,blades are 36 x 16.5 herrings 5 ears with a 16 degree rake, 6000 rpm is 153. This set up has good acceleration . You can cruise at 5000 rpm and will run in 110 to 115 range and if you got what it takes to push the top end it should run 165 at 6500 rpm. But hell, that is really hauling the mail !!!
