Here we go again. Last year sent me 3 engines for port side none being any good! So I built a yamaha factory 1.8. The starboard side was good from sbt but only made it 45 hours and oil pressure is gone! New $900.00 oil pump has scarring in it from shavings from engine failing. Screw these guys! They have wasted my last 2 summers and 3 vacations. I'm gonna sell it to someone as is and build a new yamaha again. The quality control is absolutely horrible! I don't know how these people are still in business! It's still under warranty and I have no confidence they can fix it. It's time to cut my losses of thousands of dollars and time and do the right avenue of building a factory yamaha! SBT F$&# YOU!
