Hey guys,

I have been researching props the past few weeks and I am interested to see if anyone on here has any experience running a Quicksilver High Five SS prop? My boat is a 03 180 Horizon with the 4.3 Merc. The stock prop on the boat is a 13 1/2 X 23p and overall I am very happy with the performance. I am just looking for an improved holeshot while I am carrying a full load. After doing some research and doing a few prop selectors on different manufacturers websites this one has caught my eye, so I am just asking for your guys opinions. Right now I am thinking a 21p Quicksilver HF SS 21p. I know these prop threads are really overdone, but I really appreciate any recomendations and opinions since props aren't cheap, and I really want to make sure that I will be happy with my purchase! Thanks in advance!

I'm about the only one here running the Hi-5. If you are happy with the overall performance of the 3bl 23P and still about 400 RPM or more below the top end of your WOT RPM throttle band, I would recommend getting the 23P in the 5 bl. If you are 200 RPM or less below the top end of the WOT RPM throttle band, I recommend you step up to a 25P (can you even get that pitch???). The smaller blade diameter lends to higher RPM for a given speed. I am running a 21P Hi-5 and get very similar top end/RPM as my 3 bl 19P.

My 21P SS will turn about 5000-5100 RPM at 52 MPH (GPS)
the 23P Hi 5 will do 5200 RPM at 50 MPH, but with much improved hole-shot.

Both are with 4 peeps, full fuel. I also noticed, the more I load down, the Hi-5 is affected less. Fully loaded I can still hit 48 MPH at about 4800 RPM, whereas the 3 bl will only hit about 46 MPH.

BTW... Midwest Propeller is the best price in the biz!

I recently put one on mine, and absolutely love it. With the 5 L Merc, I lost maybe three mph according the the speedo, and my RPMs at WOT went from 4600 to about 5100. Not that I ever drive it like that, except for testing out the two props.
The new prop is a 19 p, the factory one was a stainless 3 blade 21 p.

Also, a buddy has one on his 18 ft boat with the 4.3. He has a 19 p and also loves it. I think he lost more top end than me, but he thought 21 p was too much for his boat.

Some shops let you demo them, so you can buy both, test them out for the day, and return the one you don't like.

Thank you for the replies guys! And Walt thanks for the link to the website. They definitetly do have better pricing on these. I am thinking of the 23p now after doing some more research. Like you said Walt the 5 blades seem to run higher rpm. For the money I would hate to purchase a 21p and have the boat running to high of rpm. And 210 SS thanks for the tip about the boat shops letting you test them out, I will look into that!

I have the Hi5 19P on my 1998 Horizon Sunsport RS. I replaced a 3 blade 23P prop.

Obviously does not have the same top end and stays in a higher rpm range, but the holeshot and pulling power is awesome for watersports. If you have trouble pulling a load, I wholeheartedly recommend these props. I went with the 19P on the 4.3 and I've never regretted it.
