I may be wrong here, but I thought a high 5 is an increased number of blades, therefore will improve acceleration, but you are likely to loose top end as a 5 bladed is less efficient than a 3 bladed prop.

Well, I don't pretend to know much about this prop business, just bits of info I have picked up from chatting to mates in the trade. I have always thought high 5s were for pulling skiers or wake boarders out the water, designed for acceleration.

Yep, tried 'em all over the years. Even made my own out of washing machine parts! Sorry, Yes, I have run a few inc. 5 bladers and variable pitch and found that the 'right' SS 3 blade prop gave the best allround performance. Getting it 'right' is not so easy though.

When all things are said and done, you have to analyse your APPLICATION!
If you are doing a fair bit of skiing, a bit of trolling whilst fishing, long range cruising and possibly hooning around at great speeds, you want a prop to cover all these applications. As far as the Hi5 is concerned, it IS good for skiing, but I seriously doubt it is any good for long range cruising where you are sitting in the mid to upper range band. I really do not believe otherwise as I have these props on 2 boats and this is my experience, backed up by Barrus. Props are a black science and you can spend an awful lot of money getting it very wrong. Stick to what you have, 3 more knots at the top end spending a fortune is senseless!

BTW, Andre, if you are there, what props were you running on the twin Opti's?

any way back to the original thread after all this exciting stuff about 4 and 5 bladed props and who has and has not tried them

if you have a lazer 2 21 pitch then let me know as would like to buy it or perhaps borrow to try if possible, i have a kind offer to try one in two weeks time in cornwall which is great but i am looking to buy one anyway second hand if possible

if you have a revolution 4 or 5 star or other prop i should try then just say and would give them a go. my understanding is the 4 bladers are good for better top end!

if you have a 21 and want a 23 and i have a 23 and your 21 works best on mine etc then would be happy to swap if the 21 was better for me allround. so that is another option. otherwise i want to get one as a spare and to try.

i am looking to pick up a 19 as well as cant have too many props!
