Sr4 owners-what's your top speed/hp/engine?

[Nos4r2]

I've just upped my prop to a 14" and made WOT of 42.4mph on GPS outside Fowey yesterday (Solo,60 litres of fuel aboard, slight swell,head down, wind behind me, trimmed out as far as I dare) then turned round and repeated the run into the wind making 40mph-all without chinewalking! I wonder if having 30 litres of fuel in the bow helped stop chinewalking?

Whats yours do?

you are spot on i sold my sr4 last year it saw 33 knots with a yamaha 50. the boat was pritty settled, and i too put this down to a 75 ltr bow tank that i use to keep between 3/4 and 1/2 full.

I also had extra weight from the bigger console and aframe, probley why i pnly saw 33kts, but i never really experienced much chine walking.

may be the new boat (when it is done) will behave differently.

(add a few sand bags for stability and sacrifice a few knots) not bloody likely!!!

37mph @5900rpm on merc40 2stroke and no chine walking with new smart tabs re-fitted (wider set, closer to tubes) on 13" prop with 40liters in tank at rear and total of 270lbs in human weight up front.

31 knts, tohatsu 50 (slightly damaged prop), 2-up, slight swell. I'm guessing I get more than this with 1-up but started chinewalking pretty badly so had to trim-in and wasn't looking at the GPS at the time.

4 mtr searider two tanks full, two pie eaters 60hp merc 16" hand polished (personally) stainless prop

Hull blanked off watertight.

The engine was mounted so far up the transom it cavitated like the clappers if trimmed right out and you tried to turn left or right! the builder said it would be too high but I would'nt listen. It chine walked like crazy.

Only ever used superunleaded, no dole fins = 48knots!

Unfortunately the boat was stolen in june if anyone see's it let me know, go to hotribs stolen boats http://www.hotribs.com/forums.asp the one with the picture.
