I was told today that I can put a 4.3L mercruiser on a 2001 SX 175 Glastron. Right now I have a GS 3.0 Volvo Penta,
Ayuh,.... Welcome Aboard,..... Basically, you were told wrong,.....
While anything is possible when ya throw enough money, 'n time at it,....
The best possible answer is to find another Volvo dressed motor for yer boat,....
Another 3.0l, unless ya wanta change the outdrive too,.....
