This one gets the most use. 1973 Correct Craft Ford inboard(~45 hrs./yr): Last changed before my purchase in 1998. All used in a sandy bottom shallow lake. Courage? lunacy. 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. Factory OEM parts last a lot longer too. There are outboards on out lake from the 50's & 60's that have never had an impeller change-out. 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.- Hide quoted text - - Show quoted text - Similar to a big outboard. |
