Default How Fast 1994 Sonic 42 Triple Hp500?

i JUST CAME BACK TO SEE ONE. WHAT PROP ARE SUPPOSED TO BE ON THOSE?

THEY ARE 1.5 RATIO BRAVO, BUT HAD 22 4 BLADE MACK PROP??????

I THOUGHT IT WOULD SPIN HIGHER PITCH THAN THAT... BUT IF THAT IS THE RIGHT PROP SET UP, THAT WOULD REACH WHAT... 70-75?

Not a chance with 1.5's and 22 pitch! More like in the high
60'smaybe 70 with that set up. Should be able to run 25-26's which would get you in the mid-high 70's on 4 blades.

45 SONIC triple 575 sci 86 tops running Bravo Drives turing 4 blasdes. Have to check the props and sea whats on there. Anything faster than that is on a trailer going downhill with a tail wind. No Ransom, triple 900 Teague motors running #6 drysump drives 104 tops .

Must be a mistake somewhere. A 42 with 2 502 MPI 415 hp will turn 22 pitch 4 blades and go 60 mph +. With 3 500's it should go 78-80.

OK OK. 42 Sonic with 500's 24p or 26p running right at 70.

45 Sonic with triple 575's running I believe 32p runs right around 90.

386 With twin 900's #6 drives not sure of prop ran 106 all day.

My 45 triple 500EFI's turning 26p runs right about 80

Madcow on here has a triple 42 not sure of what power or props.

Checked the pitch on two of the Sonics at the shop today. Triple 575sci are running 28" pitch. The 42 SS Boarder Line running triple 650 Inovations I believe is running Hydro-motive 4 blades 31" pitch. Note sure of the speeds but should be in the low 80's. She is listed in the boats ads for sale. http://www.offshoreonlyclassifieds.c...o23275-en.html
