Every 2 years, especially if your boat goes in shallow water kicking up sand. I ahve mercruisers, and the alpha1 is a fairly simple procedure to inspect and change out. I look at mine every couple years. When I got my 23' Marquis last year, I pulled the bottom leg right when I got it home after purchase (in late fall) , and looked at the impeller while winterizing the boat.. It was getting some wear. So I left it apart, and this spring installed a fresh one and re assembled the lower end. Like I said, it's not difficult at least on a Mercruiser. I'm not familiar with other brands though. |

JimH knows the dangers of not changing his impeller, it can result in a very expensive mistake if you don't change them biannually. |

Rob On the latest Yamahas and I assume on other brands, you can get a cooling water pressure display on your multi-function gauges. My guess is that if you know what your pressure usually is under varying conditions, you will be able to tell when something is amiss, such as an impeller going tits up. Maybe. :} An inspection port would be nice. |

The only time I've ever changed an impeller was when I noticed that the water pressure was a little low on one FICHT I had on the original Contender. It must have sucked up a piece of sea weed or something. Changing one every two years is over kill in my opinion. Other than that, I can't think of a time I've ever changed one other than an older Merc that I rebuilt one time. |

Rob Until I purchased it in 2005 my 1997 Glastron spent it's entire life on an inland lake and trailered. Starting in 2005 it's new life was on Lake Erie with a lot of time anchored near beaches in sandy water. I have to back over a sand bar to get near the beach, kicking up sand while running in reverse. The impellor failed last year causing some major damage to the engine due to the engine overheating. It also caused me to be towed in twice last year. I will continue to change mine out every two years. It is cheap insurance for me. Is this something you do yourself or do you have a mechanic do it? I've never owned an I/O, and therefore, obviously, know nothing other than the generalities, about I/O innards. In the good old days, my father let me change the impellers on the lower units of customer outboards, but in those days it was a simple, straightforward mechanical operation. These days, I wouldn't attempt "mechanical" work on a modern, high-tech outboard beyond fluid replacement. |

If the water was that shallow, I'd get out and pull the boat rather than fill up the water pump with sand. I think this "fill the water pump with sand" is a bit over hyped. What I *know* is that John did not comprehend what I said. Let me repeat.......I need to back over a sandbar to get to the beach. I cannot jump out of the boat to pull it to the beach as once over the sandbar I am in water over my head for 30 or so feet. Although my IO is raised, I still kick up a lot of sand when passing over that sandbar. The water pump is not filled with sand but there is enough sand to act as an abrasive on the impeller. More experienced boaters understood what you meant. Anyone who has fished the flats in Florida and who has had to motor slowly over skinny water to get to a channel gets it. |

No problem, do what you think is best. It's your boat. I will probably be up on the trailer next week for my 2000 hour and I will post a picture of a 1700 hour impeller running in the water I posted the other day. I am still holding 3 PSI at idle and 17-18 at 4500. That is pretty much what it did new so I bet it is not that bad. gf, I am glad you have not had any problems with your impeller, and I hope your luck continues. I follow the mfg'er recommended schedule in changing the impeller, oil and outdrive fluid, and never worried about about the few dollars it cost. All of these are very easy DIY projects. It was very cheap insurance. I have never had an accident in my car, nor have I filed a claim on my homeowners insurance, but I would not consider discontinuing my insurance. For what it is worth, here is the recommended maintenance schedule: http://idlezone.com/html/boating_faqs.html While they recommended changing the impeller every 100 hrs. I only changed the impeller after the first 100 hrs, then decided I could do it every other year. At the very least, I hope you are pulling your impeller and inspecting it on an annual basis. If not, I hope your luck continues. |

PS - When I am crammed into the bilge on a hot July day changing the oil, sweating my ass off I really wish I didn't change my oil every 50 hrs, but since my boat has over 1000 hrs on it, and I have never had an engine related problem and it purrs like a kitten, I will continue to change the oil every 50 hrs. I normally run my engine at 3400-3600 rpm depending on the number of people on board. I change the oil in my car every 3000-3500 miles, and my car engine normally runs at 2400 at highway speeds so it is comparable to the way I service my car. Since the boat will sit for days without being used and will run for long periods at high revolution it is more important that the oil is in top condition. |
