I hit some rock on the river last year and some water must have gone in the lower unit . I did not noticed that there was any cracks before I stored it or the winter but when i removed the cover , there was definitly 2 big cracks in the lower unit . My boat is an 84 Formula 2 SC (550 hrs) with a Volvo AQ 260A ( bought it last year with no orriginal manuals) . The drive says 270 but Volvo says that they only put 280 with these engines, so I don't know what I truely have . Is there a way to know?
When I looked at the exhaused on the lower unit , it is thin and flat and looks like the 280 type but I have seen pictures of the 270 looking the same and 270 with a triangle as an exhaused.
The engine is 5.7L engine .
I don't know where to look for the serial number if there is one. ( the 280 manual that I got don't say and can't find a 270 manual )
Then where can I find a replacement unit or case a reasonnable price?

Thanks in advance for all your help
