ya freakin me out ! How on earth can a $17K-23K outboard have a failure like within the first year of operation? The JDPowers folks should go to jail for fraud. An oil pump should last 10,000 hours at least!!! The fact that an oil pump let go is telling you that the product is poor quality...no question. An oil pump should *never* *ever* go...and should work for least for 20 years.

What do you think the Mean time between Failure is on an entire outboard? (MTBF) I bet it is like 10 hours....really. This is the kind of rating system I would like to see on these engines. It is downright embarrassing. It would be easy to compute this to survey the repair shops, they now know exactly how may hours between each repair.

IMO it is impossible to make a *relaible* power plant out of a raw salt water cooled, aluminum block high performance engine...2 cycle or 4....it just can't be done. AL has good heat transfer features BUT...is too weak, is not good with salt water, expands and contracts too much and is subject to corroision and is a poor choice to when in contact with other materials...ie steel. We are using the wrong materials for the environment. The engine has to be cooled with coolant, not raw seawater (step one). The block material needs to be changed to something more stable. The casing needs to be also changed to something more stiffer and harder. Anything that sees seawater should be non-corrosive. Electronic should be sealed completely and are good for submerged operation. If something craps out is should e easily replaced. The parts (like oil pumps) need to test for 100K hours before breakdown. What they are selling us is utter junk. I think if they are going to use seawater to cool they need to move to a ceramic block or some exotic composite. IMO lower units are going cause there is too much flex in the system.

And by relaible I mean a machine that can last 10+ years being run every day and starting when you turn the key while being maintained by the dealer 2X per year. I am talking about 300-500 hours per season every season for 10 years.
That is NOT asking that much IMO!!
