Remember the days when you didn't know an impeller from a propeller? Well that's me. I thought i would start off with something easy like changing the impeller, but it doesn't seem to be going as easy as the posts I read. I'm stuck at this point, what do I do next?!?! Where is the darn impeller?!!?Thanks in advance!!!

She's in there. Looks like you removed a lot of unnecessary hardware. Probably easier to access from the back! ------------- |

So far I've only removed 4 bolts!!! Do I have to remove the hoses to get at it???

By back, do you mean here, when I say I don't know what I'm doing, this is not an understatement. Against my better judgement, I'm relying on you here HW!!! Where's Pete?!?!?

Looks like you might want some new hoses too! ------------- |

Hey , I'm open to all suggestions, I think I can handle replacing old hoses...But first things first, where's my impeller hiding and how do I get to it?!?!  ------------- -Adam 1973 Skier |

Adam, HW is right that it is in there someplace!! Really, your arrow is pointing to the pump body were the impeller is. The front section is the bearings and shaft seal. Remove the hoses and the 2 lower bolts from the pump "L" bracket and pull the pump out. The rear of the pump will have some screws holding the cover plate on. Remove it and you'll find it. Do you have the impeller yet? ------------- /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 < |

Thanks Pete, yes, I have the pleasure of going right to SECC to get parts, I picked up an impeller and a 143 deg thermostat. I just don't want to start removing bolts, clamps and hoses when I don't know what I'm doing. So I have to remove the pump to access the impeller, will head outside now, remove the hoses, remove the pump. Thanks again Pete, for a minute there I thought I was going to rely on HW!!! Do I remember something about marking the pump so I don't put it on backwards being important. ------------- -Adam 1973 Skier |

You'll be fine! You have the pictures too. The bacerds problem is more of a reversing the suction and discharge hoses issue plus a RH or LH engine question. ------------- /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 < |

Thar she be...
Thanks for your help Pete, I appreciate you helping me with something so minor. Now I know why Jbear says he never lifts his engine cover, it can be a little intimidating when you don't know what you're doing. I want to replace these old sections of hose. Just go to an automotive store? Thanks again. ------------- -Adam 1973 Skier |

You may want wire reinforced hose at least on the intake side so it doesn't want to colapse. I used marine wet exhaust hose that you can find at west or skidim<---probably cheaper. ------------- http://correctcraftfan.com/diaries/details.asp?ID=2331&sort=&pagenum=12&yrstart=1986&yrend=1990" rel="nofollow - 1988 BFN-sold "It's a Livin' Thing...What a Terrible Thing to Lose" ELO |

Adam, Greg's correct that reinforced hose on the suction is a great idea. A decent auto parts store should have it. I would replace it all the way back to the through hull in the bottom of the boat. Wire reinforced isn't the easiest to bend but see if you can eliminate at least one or possibly even both elbows at the pump. Couple of reasons; Each hose clamp is a potential spot to leak (suck air) and each 90 degree elbow adds the equivalent of 10' of additional hose in terms of restriction. Try to make a gentle bend even if you go up and over the top of the oil filter and then down next to the oil lines to the trans. ------------- /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 knew this from working with large aquarium systems in the past but never in such specific terms. The 10' is horizontal or is it a vertical head? It can't be vertical...the pump wouldn't do it. What's the formula please sir! ------------- http://correctcraftfan.com/diaries/details.asp?ID=2331&sort=&pagenum=12&yrstart=1986&yrend=1990" rel="nofollow - 1988 BFN-sold "It's a Livin' Thing...What a Terrible Thing to Lose" ELO |

Greg, The restriction caused by elbows is slightly different than suction/head pressure. Vertical head equals 1 PSI every 27" of the vertical caused by gravity so if you pumped water 90' vertical, the pump would need to develop 40 PSI just to get the water to the top. Restriction in piping is just the friction of the liquid, gas or vapor on the walls of the pipe. In elbows, the friction gets real bad. It's like trying to suck the same amount of liquid through a small straw rather that a larger one or a long straw rather than a short one. This restriction in the pipe itself is however equated to head pressure (I've always used available charts and never a particular formula) so you can compare the restriction to the pump curves that are show in head or PSI. A good example of flow restriction in pipe only without any vertical head would be a hydronic in floor heating. There isn't any vertical head because it's a closed system and even if the pump/boiler is in the basement, the hot water going up also has to go back down! With our boats, vertical lift (suction) really isn't a problem because there isn't that much lift however we must use the rubber impeller type pump because it has to develop a positive suction. A centrifugal pump (the circulation pump) won't do that. ------------- /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 < |

Man I like the way you said all that Pete. All that suction vertical head friction talk is gettin' me going. If I know woking on the boat could be this much of a turn on I might go under my motor box more.

Pete, do you really think there's enough room to eliminate both these 90 deg angles? I don't mean to question your good intentions,but is this really something I could do. I'm all for it if possible. Just wondering, Thanks again. ------------- -Adam 1973 Skier |

Adam, You're handling the impeller so I sure think you could do this. Have you found the hose yet? Before cutting it, you'll need to play with the routing with consideration of how well it flexes in the corners. Stick the hose in some rough positions and post some more pictures. The elbow closest to the pump looks OEM because of the red paint on it but the second gray one isn't. this second one is even plastic which isn't the greatest to clamp heavy hose to. Someone added it at one time but can't really tell why. ------------- /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 Im going to say that someone added a different pump . That is why the extra elbow .
Adam you may want to play with rotating the pump on the mounting holes on the front . What do you think Pete? ------------- Pat http://i175.photobucket.com/albums/w146/72ccfan/100_5977-1.jpg - My 72 Skier Rock River Dixon,ILL. |

Pat, It's a Palmer marinization and everyone seemed to use different pumps. Even same year same marinizers used different pumps. I feel the chances of it being original are good just because of the paint on it. The L bracket is the only thing that isn't painted. I too thought about rotating the pump but you then would end up with a elbow on both the intake and discharge. Looping the suction hose in a radius was the best I could come up with. ------------- /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 < |
