New Scarab owner, needs help with propp choice.
 

Hey guys! like the topic says, i just bought a scarab!

it's a 29 foot with a singel merlin 580 ci engine. they guy who had it before me spent huge amount of time on rebuilding it and did not have the time to try out a propp before i bought it from him.

does anyone have a 29 with a singel engine and have some ideas for a propp for me? the engine have 661,9 hp. what do you guys use? 3, 4 or even 5 blade?

would love to attach pictures but i cant figure out how the hell to do it?

A friend had a 29 scarab with a super charged 502 making 640 h/p and used a 28 four blade prop ran 71 mph gps

perfect, thats a start for me. ill have to wait for summer to try it out. thanks!

i have a 28 excel with a zz502 pushing 500hp with a 4 blade 24 p and toped out at 67 mph in ruff water

oh and to post pics go to photobucket open an account upload ur pics there and u need to copy the url of each pic and paste the url on here

sounds like a 4 blade 26 p will be a good place to start. thanks.

here is some pictures: http://www.offshoreonly.com/forums/s...scarab-13.html

I knew of a similar set up wtih a left handed labbed 27p hydromotive which ran really well

just an update, i got the boat and tried on a Bravo one 4 blade 26 pitch. three 100+ kg guys in the boat, full tank (100 gallons, 375 litres) the boat mad 60 knots very easy.

since this was the first run, i did not want to put to much pressure on the engine. i belive i will be able to squeeze a couple of more knopt out of her later this summer :-)

Kilos....Knots...Litres...Where's my damn calculator when I need it!

Just kidding. Glad to hear you had a good first run.

Help me with my Prop
 

I have a 23 scarab scs with close to 600hp and need help with a prop. I was running a 26 4 blade that was labbed and at 80mph was at 6000 RPM. Last weekend I bent the prop past repair. Just wanting some feedback if I sould pitch up to a 28 or 30 and since it is a left hand drive boat it a left hand rotation prop would be a better choice?
