hey Gone Fishin , I really don't think oil was the issue on your friends motor. I guess you really have to split boat owners into two groups , those who maintain their own motors and those who don't. I think your friend was probably in the "not so much" category. Your friend probably had a few warning signs .
Merc compressors will begin to sqeek long before they blow due to restricted oil flow. Corrosion in the fuel system in a 2005? Could be any number of things, but it sounds like it was living a hard life. Running cold is just as bad as running hot , stuck thermostat?
The Merc smart guage system is the best guaging I have used. It gives you all the info you need to know to have a healthy motor,but you have to be able to interpret those signs.
I would not use non recommended oil if you are still under warranty or don't do some of your own maintenance. Another important factor is not to mix and match oils. Find one and stick with it for a few tubs. Don't like it ? drain the tub and move on.
Oil is definately important , but I have seen manafacturers void warranties blaming "inferior oil" when the problem was obviously something else.
Hey he's got a new motor , he should be a happy man!
