Re: too many impeller choices
Funny, I've used Sierra ever since there was a Sierra and rarely seen a problem. Y'all must think that the OEM's actually make their own impellers. It's all outsourced to whoever gives the cheapest price.
Half true. While cost does play an important factor in their outsourcing, quality is higher.
I have not really heard of an OEM impeller failing on startup? I haven't encountered it anyways. Doesn't say a lot, I haven't done as many as some of the large scale mechanics on this site, but in my tiny little world all has been well.
Google search failed Sierra impellers and pour yourself a cup of coffee
I am not trying to drag Sierra through the mud. I have an account with them and buy many, many of their products. Impellers are not one of them however. They may have improved the quality standards over the last couple years, but I am confident in the OEM impellers so stick with them. Would I put one of their impellers in one of my own motors? Maybe, but not in someone that pays me to do a water pump job. I wouldn't want a failure to be blamed on me. They are not always that much more cost wise. Well worth the extra investment in my tiny little brain. Your water pump is a pretty critical aspect of the outboards operation right.
Wasn't exaggerating on the number of failed ones I have pulled out either. Ill go take a picture of them all. Brand new each one. Most had the hub separate from the rubber, but about a third had the key tear a groove in the hub. Strange to see indeed.
