42 fountain speeds
 

What kind of speeds will you see on a non step 42 with 600sc's and number 3ssm?

No one's had a boat with this type of set up before

93 42 Fountain non step 557 with 8-71 blower, Bmax/Imco , 88mph

Would you say thats a pretty good comparison ?

what h.p. and what prop?

Got an 85 12 Meter (40 no step) with fresh 540's dyno @ 700hp (natural) with SSM3 w/ 16.5X25's and runs about 76, hoping to get to 80 in the right conditions and maybe 1 step up in prop. Might be a close comparason?

Thanks, I was hoping it would do 80mph but I guess it takes a lot of HP to get there. I bet with the SSM3 they handle great.

86 12 meter with 496s never dynoed but gotta be close to around 600hp. 73 GPS and that's with trs drives

According to the old owner, it should be right around 800 each . Went with 27p 4 blades. Light fuel and two people. Would love to break 100+ but might need lots more powers or need boat :(
