Didnt somebody mention on here before that Yamaha makes the powerheads for Mercury now.
Also, I know a guy that wrenched on outboards a few years ago.He told me Suzuki is a good engine till something goes wrong.Then look out.Something about the way the pistons,rods etc were put together, I think.Been 6-7 years ago so that might be toatlly irrellevent now though.
