Re: Mercruiser or Volvo which one
I have owned a OMC, a Yamaha(both no longer made) and a Mercruiser outdrive. Never a Volvo, but I can tell you the newer ones have an issue with the tilt pumps blowing seals. My buddy just had this happen and after some research I found out it was pretty common. They had to replace the whole pump, but the good news is that it is easy to replace, just about a $400 part.
The engines are all the same. They all use pretty much the same GM engines. My Alpha outdrive has been pretty good to me, but that all comes with maintenance I believe. Mine has been trouble free for almost 4 years,and I use my boat a lot.
