hey guys i just got a 93 glastron ssv 175 with a Volvo penta 4.3, i believe it has a Volvo penta SP drive? im no expert and new to most of this, manual for engine and drive is on the way but how can i figure out which model the 4.3 is? is there castings somewhere? and is the drive volvo as well? it just has a sticker on there that says SP. i'm to excited to wait for the manual, thanks all
