Yup. Thats my old 1998 37 OuterLimits. I see you changed the hatch from a sunpad to a hatch with scoops. She looks great. I hope you are really enjoying it. My best run was 114mph with 5 pob, 1.36 gears, 4 blade round ear bravo props.

How much power do you have now?
What the max rpm.
What gears and props.
What top speed.

547 cu in 871 blowers on xr 1.36 drives inbetween props right now but saw 108 end of last season. Like you said It's a great boat.

Glad to hear you are enjoying her, and very glad she found a good home.

Go fast! Go safe!

Many pics at of her and others at www.dkorinc.homestead.com

He said single step Kenny, not a Quad Step.
Plus, they got different drives.

Now ........ :signs069:

check your data, I would expect more rpm to get those speeds with a 32 prop, with 1.48 ratio

What rpm range is the motor built for? What is the rev limiter set at?

Its a great boat at any speed, but I am thinking 110mph for #5s and 860hp a side. Remember the 37 with 900sc, #6 runs 117ish.

Post a pic of you ride.

Keep in mind that Mercury #6 props are not true to stamped pitch. They are actually about 2 inches TALLER than they are stamped. Hering props are true to stamped pitch as are Rolla and TU CNC's.
