ariip 0 Report post Posted March 29, 2015 Hi, I own a monterey 295 SCR and I have change her engine for a Volvo Penta 8.1 GXi-F, 420 HP (2007) with a 1.78 stern drive DPS. Do some body can inform me what propellers I should use? F4 or F5 or other? Thank you a lot Share this post Link to post Share on other sites
