Hey guys,

I'm new to the boating world and just purchased a Bayliner 195 with 4.3L I/O - alpha 1 outdrive. I know it's not the best thing for wakeboarding but it's what I have...

Anyhow I have read here and there that there are better prop's for wakeboarding as far as pulling someone up. I wanted to ask your suggestion what would be the best for me.

Thanks in advance!

the best you can get is the mercury high-five prop. Five blade stainless is great for wakeboarding because it gives a better hole-shot and speed control. As for the pitch, get something under 20 if you plan on adding ballast to your boat, if not 21 is probably good

What is the difference between stainless and aluminum?

Is there a big difference between 4 and 5 blade props?

Thanks for the suggestions!

5 will get way better hole shot than 4, you loose top speed

stainless better hole shot, a slighter less rpm and speed than AL

a 3 blade al will out run a 3 blade stainless

But because we are on wakeboard forums, we assume that top speed doesnt matter. So to answer his question, a stainless prop is better because it will last longer, comes in 4 and 5 blade models, and has high resale value.

Get the high five.

You're right, I'm not really concerned about my top speed. Does a 4 or 5 blade prop make the boat less "Squirelly" when going slow? Just curious...
Thanks!

it has more surface area so it holds the water easier than a 3 blade, so it maintains speed better. As far as pulling the boat side to side when someone has tension on the line, a little, but not a significant amount. its best to compensate for that with a good driver Very Happy

Where do you guys buy your props?

What do you guys think of this:

Is that a waste?

I was looking at high fives and it seems they only make 1 size diameter prop. I've currently got a 14.5" 19*. The high fives on the website I saw were only 13 1/2 diameter I think it was. Is it typical to have a smaller diameter with more blades on the prop?

yep!

but the bigger diameter the more bite

here is a thing about props

I tested it out this weekend to get some accurate numbers for you experts as I'm new to this game...I would like to get a little pop out of the hole, maybe a little more control as well... Not really concerned about top speed because I never run her wide open.

WOT with trim all the way down was right at 5,000 RPM's and 44.3 MPH.
If I trim it up slighty it will go 1.6 MPH faster. If I trim it up too much RPM's hit 5,200 and rev limited kicks in.
The current prop is a 19* 14.5" aluminum.
I honestly don't know the weight, because I have read different #'s but I believe it is meant to weigh about 2,700lbs. I typically have 4 total passengers including myself with minimal gear. The engine is Mercruiser 4.3L 190HP with Alpha I drive.
