Try to borrow one and test if FIRST before spending real bucks on it,your already at 6' which isn't terribly deep for a single. My prop c/l is 7 1/2 on my boat and so far I gained ZERO with a 2" shortie plus boat no longer carries the bow well. Just tried a 1" spacer,carried bow better but still not real good,zero speed increase,Smitty

First of all, what power/speed are you running?
A noseconed shorty (like the Imco, Sportmaster) will slow a (400hp) 65 mph boat down, but could(!) make (800 hp) 90 mph boat gain 4 mph.
If the current prop to hull dimension is 6", and you go up to 4", without a notch (donŽt know if a S26 has one) you may well be already too high for a mild powered boat.
Power, current speed and x dimension?

Let's just say I will hopefully be placing some orders with you soon! What's up with KW..did you find a place to crash? Hope to see you there
Noise...for the record I have no experience with a 2" shorty on a 26. Sorry for the hijack. Keeps the thread at the top though

Motor is aound 580 - 590 HP at the prop. Top speed 71.6 at 4950 rpm. Motor peaked at 5300. So I have some more room to play with. The boat does has a notch.

580 hp, 71 mph and you are still 400rpm below the peak power.
What prop are you running. IŽd expect it to be a 26" (on a 1.5 drive) with those figures. Labbed?
Yes, IŽd say you are ploughing deep with your current settup. The picture confirms that, too. The notch will effectively mean that the drive can be a tad higher than a similar hull without a notch, anyway.

THe drive is a 1.5. I running a stock B 26. I would like to try a 26 labed. Thinking I pick up a few RPM on the top end. What would the do for my mid range (cruise speed)?
Guess I'll have to wait till next summer.
