Looking at a boat with a 1997 Volvo 4.3L GS. Owner states this is very low hours and well maintained. From the photos it looks like new, but when I get to look at it in the flesh anything particular I should be looking for?<br /><br />Any problems with this engine/outdrive?<br />What is the difference between the 4.3 GS and GL?<br /><br />Thanks in advance
