So I thought many of you might be bored of your silly little ski boats by this time of the season, and so I thought I would lay out my son's eagle scout/winter project. You may remember this thread: http://www.correctcraftfan.com/forum/forum_posts.asp?TID=34693&title=the-mighty-seacamperwill-this-throw-a-good-wake" rel="nofollow - Seacamper The long and short of it is that I did not know what to do with the boat. Mrs Seacamper is bugging me to get it out of the driveway, and does not want it at the dock. I do not want to get rid of it, and my youngest has been drawing pictures of what the boat will look like since he was 4. (He is 14 as of yesterday) Soooooo, we decided to donate the boat to the local American Legion Post 8 that I am a member of. They are located on Lake Silver in Winter Haven Fl. The Legion also graciously donates dock space and boat slips to the Cypress Gardens Water Ski Team (CGWST), and Lake Silver is where the CGWST performs now that Legoland took over Cypress Gardens. The plan is for the Legion to make the boat available for the Sea Scouts that they sponsor, to use as their boat. If you are unfamiliar with the Sea Scouts, here is their website: http://seascout.org/" rel="nofollow - Sea Scouts Here is the plan: Here is the boat as it sits now: http://s266.photobucket.com/user/turninggrey/media/Seacamper/IMG_0002%201.jpg.html" rel="nofollow">  We obviously need to shoot for a military theme because of our connection with the Legion, so we are shooting for a "Swift Boat" look: http://s266.photobucket.com/user/turninggrey/media/Seacamper/painting_Swift_Boat_2_web.jpg.html" rel="nofollow">  Here is a really bad concept picture using all my computer skills: http://s266.photobucket.com/user/turninggrey/media/Seacamper/IMG_0002%201abcde.jpg.html" rel="nofollow">  We plan to add a mud pump or two and create a water cannon on the roof and various jets to attempt to do this: http://s266.photobucket.com/user/turninggrey/media/Seacamper/fireboat_water2.jpg.html" rel="nofollow">  We will also add lights for night effects something like this: http://s266.photobucket.com/user/turninggrey/media/Seacamper/2580912528_8a12630cf3_b.jpg.html" rel="nofollow">  The boat will be used by the Legion as a float in parades, and it will be used in the warm up acts for the CGWST monthly show, with Sea Scouts manning and maintaining the boat. We are going to get Jbear and Eddie signed up with Jbear as the silver haired skipper, and we are going to get Eddie in a eye patch and head scarf. Any suggestions on how far a mud pump will fire a stream of water?? I will update this thread as we further the project.

Tom, When you say "mud" pump, what type of pump are you referring to? If a solids diaphragm pump, they do not develop much pressure. What is needed is a dual volute double suction semi turbine type like this:  ------------- /diaries/details.asp?ID=1622" rel="nofollow - 54 Atom /diaries/details.asp?ID=2179" rel="nofollow - 77 Tique 64 X55 Dunphy Keep it original, Pete < |

| I think he meant trash pump. But, I agree with Pete's assessment that it won't develop the pressure needed to squirt that high. |

My initial thought would be to use an irrigation pump that many people on lakes use to draw water from lake to sprinkle lawns. That would give you enough pressure and volume to make 3-4 impressive water cannons.... in my mind. ------------- 2000 Air/Sport 1978 T16 |

Yeah, the idea of using the exciter for a flyboard is negated by the 200+ hp jetski's in use now. I will look for the sunglasses. Patrick probably found them and is going full HW with them. ------------- 1980 Ski Nautique Boat Bar 1988 Mastercraft Tristar Open Bow 1988 Mastercraft Tristar Closed Bow 1969 Seacamper Houseboat 1986 Harris Pontoon 2004 Seadoo GTX SC + Flydive Xboard 1999 Adventurecraft |

Hey Pete, I was hoping I could reduce the nozzle on a Harbor Freight 6.5hp unit. It would go from 3" to 1". Would that work? ------------- 1980 Ski Nautique Boat Bar 1988 Mastercraft Tristar Open Bow 1988 Mastercraft Tristar Closed Bow 1969 Seacamper Houseboat 1986 Harris Pontoon 2004 Seadoo GTX SC + Flydive Xboard 1999 Adventurecraft |

| sure it'll "work", just like sticking your finger over the end of the hose makes the water shoot farther, but there's a limit. |

Nope! High volume low head isn't what's needed. The typical centrifugal in a high head version can make 120' but not an "irrigation" which is basically what CQ posted. ------------- /diaries/details.asp?ID=1622" rel="nofollow - 54 Atom /diaries/details.asp?ID=2179" rel="nofollow - 77 Tique 64 X55 Dunphy Keep it original, Pete < |

I was thinking the same but I would need a pretty big ac generator on board. It is not out of the question, but I was hoping to put 2 "trash pumps" on board and hard plumb them, one dedicated to a water cannon to spray the clown act, and one for 4 nozzles located at the 4 corners of the cabin for effects. I will also install 2 masts to hang speakers and lights. So am I way off base on the HF pumps? http://www.harborfreight.com/lawn-garden/pumps/65-hp-212cc-2-in-gas-engine-clear-water-pump-9540-gph-69774.html" rel="nofollow - 2" Pump http://www.harborfreight.com/65-HP-212cc-3-in-Gas-Engine-Full-Trash-Pump-264-GPM-69746.html" rel="nofollow - 3" Pump ------------- 1980 Ski Nautique Boat Bar 1988 Mastercraft Tristar Open Bow 1988 Mastercraft Tristar Closed Bow 1969 Seacamper Houseboat 1986 Harris Pontoon 2004 Seadoo GTX SC + Flydive Xboard 1999 Adventurecraft |

Reduction of the orifice will only develop the max head listed of the pump. Keep in mind the max head is typically the shut off point of the flow. Considering the 3" discharge size, it's a high volume low pressure pump. Just how high/far do you want the water to go? ------------- /diaries/details.asp?ID=1622" rel="nofollow - 54 Atom /diaries/details.asp?ID=2179" rel="nofollow - 77 Tique 64 X55 Dunphy Keep it original, Pete < |

Pete, what are those pumps used for, fire trucks? Its really a price thing. We want to be able to shoot the clown act with the water cannon, and we want to hose down the "Splash Zone" during intermission. I want enough spray to look good, but I don't want to break skin. This all needs to be in the scale of a 24 foot boat verses the 70 foot boats in the pics above. ------------- 1980 Ski Nautique Boat Bar 1988 Mastercraft Tristar Open Bow 1988 Mastercraft Tristar Closed Bow 1969 Seacamper Houseboat 1986 Harris Pontoon 2004 Seadoo GTX SC + Flydive Xboard 1999 Adventurecraft |

I am guessing 50' or so, possibly 35' high? Set against a very small lake and right in front of the crowd line or at least just offset from the jump which I am guessing is 100' from shore. ------------- 1980 Ski Nautique Boat Bar 1988 Mastercraft Tristar Open Bow 1988 Mastercraft Tristar Closed Bow 1969 Seacamper Houseboat 1986 Harris Pontoon 2004 Seadoo GTX SC + Flydive Xboard 1999 Adventurecraft |

Both these pumps have average max heads of 85' and 97'. That's roughly 35 to 45 psi which is lower than what the typical house has. Turn on your garden hose and stick it vertical and you'll see the effect. I don't feel that's what you are looking for. ------------- /diaries/details.asp?ID=1622" rel="nofollow - 54 Atom /diaries/details.asp?ID=2179" rel="nofollow - 77 Tique 64 X55 Dunphy Keep it original, Pete < |

Tom, http://www.northerntool.com/shop/tools/category_water-pumps+engine-driven-pumps+engine-driven-high-pressure-pumps" rel="nofollow - Here's some engine driven centrifugal pumps that are considered to be high pressure. The next step up would be getting more into fancier turbine types similar to the one I pictured. You need to look at the head ratings as I feel it's more accurate than just psi. 1 psi is equal to 2.31 feet of head. In other words, if you had a vertical length of pipe filled with water and applied 1 psi at the bottom, the pressure would push the water up the pipe 2.3 feet (27.6 inches). You also need to factor in the suction lift which basically is deducting the lift in feet from the total head. The suction lift is the vertical distance from the water to the pump. ------------- /diaries/details.asp?ID=1622" rel="nofollow - 54 Atom /diaries/details.asp?ID=2179" rel="nofollow - 77 Tique 64 X55 Dunphy Keep it original, Pete < |

Also, you need to look at placement. If there is not enough head on the suction of the pump it will sound like you are pumping rocks (cavitation). The longer you run like that, the less performance you get out of the pump & the faster you destroy the impeller. Check the NPSHr (Net positive suction head required). Getting it below the waterline is best. If you're only running it a few hours at a time 6 or 8 times a year, you probably won't notice a problem for 15 years or more. ------------- '92 Sport Nautique |

These were primarily developed as booster pumps on fire sprinkler systems. The design is still common for sprinkler systems were there isn't enough GPM and PSI from the city water supply. ------------- /diaries/details.asp?ID=1622" rel="nofollow - 54 Atom /diaries/details.asp?ID=2179" rel="nofollow - 77 Tique 64 X55 Dunphy Keep it original, Pete < |

If you are looking for a small budget pump, maybe consider a stand up jet ski engine/pump, You can get these cheap. May take some engineering to adapt it to a hose. ------------- “Beer is proof that God loves us and wants us to be happy.” Ben Franklin |

The jet ski pump set up is really pretty brilliant. Pm me if you decide to go this route. My little brother knows standup jet skis and jet skis in general better than anyone I know and probably has multiple pumps and engines laying around. If not, I'm sure he could help you find one. ------------- 2000 Air/Sport 1978 T16 |

I think you'll be very happy if you can locate a beater jet ski or waverunner (like free) and start there. You will have a gasoline powered engine and a pump all together as a starting point. Look at those goofy jet platforms that lift adults 20-30 feet in the air! Seems like all you need is a manifold with the outlets wherever you need them. The throttle can be adjusted for spray distance (pressure). My neighbor has a fleet of the dang things in her yard and she would probably not even miss one. Craigslist is your friend. |

I feel you should take Jake up on getting in touch with his brother. My concern is what happens when restricting the output of the typical PWC pump. You may need to by-pass some of the water? I've never seen a performance HP/GPM/PSI curve for them. ------------- /diaries/details.asp?ID=1622" rel="nofollow - 54 Atom /diaries/details.asp?ID=2179" rel="nofollow - 77 Tique 64 X55 Dunphy Keep it original, Pete < |
