quicksilver 21p lazer 2 prop in stainless

Does anyone have a 21pitch lazer 2 that will fit an opti 200. I am thinking of getting one to compare how it performs against my 23 pitch. I wanted to borrow one first if i can to see what difference it makes but if you have one for sale then i would be happy to buy it if the price is right.

for borrowing one i can pick it up or pay postage etc

drop me a pm if you can help, thanks

You're over-propped at 23". Who's idea was it to put that on there? I'd buy a 21" and maybe keep the 23" for distance work. My Merc inboard @ 260hp and buckets of torque struggled with a 23" on a boat that wasn't overly heavy. The Laser 2 above 150hp and 22ft is really designed for inboard installations, Perhaps you could look at the QS Vengeance (which I run) which is more of a big HP outboard prop.

I have been running in so far so not really been able to see if the 23 would be the best option, i was happy to pull a higher prop for longer distance cruising but to be honest i want one of each so can switch depending on what we are doing. I will check the economy and rev and midrange and holeshot and top speed on a 21 compared to mine. Ideal situation would be to buy a second hand 21 as i would like to have a spare prop anyway. 21/23 was the recommendation with the 23 as propbably ok. we will see, as it is always a bit of trial and error. we are comfortably doing 52/53 mph currently without the opportunity to play much as we only had one calm opportunity in the dark! so wanted to take care really

I've got a Laser 2 21" here at the mo. Which i'll gladly chuck on yours when you're down. I'm doing the same but a pitch lower, running 19" and 21". Roy runs a 21" and is a navvy quicker than me, he reckons that his pull-out is perfect. So with a few more gee gees the 21" might be all that I need.

Although I have a twin set-up I was interested to talk props to the THE man at Barrus. It was refreshing to listen to his recommendation to stick with what I had - Laser 2 21P on 225hp Opti's. By re-propping to a 23P he reckoned I would lose revs and speed. Out the 'hole' would be better but you would lose performance from mid to upper range revs. He also put me off Hi-5's completely and said this was 'old hat'. Again, the immediate response on throttling up would be better, but once cruising upwards of 24 knts the two extra blades would completely negate any performance improvement as they would act as extra drag through the water; a loss of speed and revs would be the result. What really impressed me was the fact that he admitted he would happily take my money for a couple of 600 props but preferred to give me good advice and rather spend my money on fuel.

Don't agree high 5 is old hat. We've seen a significant boost in mid-range performance, can cruise at 36 knots at 4750 rpm. Saving stacks of fuel.

We've lost a bit of acceleration, but overall the boat has more grip, and I'd certainly not go back.

High Five

100% agree wih free trade.....high five transformed our boat with grip, and incresed crusing speed and the same top speed.... and we droped from a 21" laser 11 to a 19" high five.

That's maybe because your previous prop was totally wrong for the boat. I'm with Mr Barrus (what does he know anyway ), Hi 5's are gimmiky old things just like the variable pitch stuff that was around for a while, in my opinion.
