High Five
Hi
I've just bought a used 19p High Five through the classifieds, expecting to get it on monday. I currently use a 19p aluminium and have wanted tp upgrade to stainless for some time, but never been sure which prop to get and I didnt want to make a very expensive mistake. However, at this price I thought it was a risk worth taking. I just wondered if anyone else has experience of using a 19p high five on a 20' bowrider with a 350 mag or similar and what effect it had on performance. I will probably get the balance checked before I fit it, and possibly also a prop lock (any recommendations?) It looks like tomorrow will be the first outing of the season so I will be able to compare the difference next week. Cheers Grommett |
Re: High Five
I haven't had any experience with the High 5 but you should see a performance improvement both at low/midrange speeds and possibly a slight mph gain because of its agressive rake. There are a couple of other members here that have gone the High 5 rouite so hopefully they will see this & chime in with their thoughts.

Re: High Five
I have a 19,(almost 20ft.) Shabah, with a 4.3 6V
I run a high five 19" These are great props, pulls like no other. Great for skiing, tubing or alot of people in the boat. Problem: I bump the rev.limter with it and only have a v6. If you have a v8, I would have a prop guy pitch it out to a 21" I think you will also hit the rev. limiter (around 5000 rpms) Mine will run 5000rpms, 50mph But great prop, wish mine had a little higher pitch. :wink_thumbup: Hope this helps, Jeff |
Re: High Five
I had my boat out today with the old aluminium 3 blade 19". Unfortunatly, the guys who replaced the transom assembly thought they had also fixed a subsequent problem with the trim switch/sender but when I went out today the trim stopped working so I spent most of the day with the drive all the way down. Still it was very calm and I only got 45mph at 4,800 rpm. I think this indicates a bigger pitch would be better but I'll see how I get on with the 19" High 5 first. At the price I paid, I didnt mind taking the risk of the pitch not being right.

Re: High Five
Having the drive trimmed properly will add an extra 2-3mph on you boat so get that fixed first. I dont recommend 'bumping' the rev limits on your motor. If you have a 350 MAG with the Alpha outdrive then the range is 4600-5000 while the B1 outdrive range is 4800-5200rpm at WOT while the 4.3L is 4400-4800. Keeping it within that range avoids excessive wear/tear and gas consumption unless of course you have deep pockets. ;)

Re: High Five
That's the prop I plan on putting on mine. Upgrading from a 17P 3 Blade Aluminum. I have one on my Outboard (Bass Boat) and it's awesome, you plane fast and it handles rough water great.

Re: High Five
Hey Grommet,
I have the high-five. I have a 5.0L LX V8. Mine is a 21 pitch. Great planing ability but i can hit 5000 RPM too easily. My mechanic said I have a 1.65 to 1 outdrive from the factory. It should have a 1.5 that is why I am pitched up a little. I think you will be happy, but I am a little leary of your 19P. Let me know how it goes. I can hit 50 by myself and about 45 loaded up. I also have a 19P 4 blade Stilleto if anyone is interested. Great prop but too small a pitch for my boat. $150 (new $400) Danny |

Re: High Five
Hi Darrel,
The prop works great and I really can't tell the difference from the 19P stilleto and the 21P High Five. The only difference is a lower engine WOT RPM. I don't know how to ship anything. I have never done it before over the internet. I was hoping you knew. Danny |
