I've got a 03' HP170 with a yammi 90horse 2-stroke. I'm just wondering what kind of mph I should be seeing? I had my buddy gps us one day using his phone and it was giving a reading of 35-36(maybe 1/2 tank gas...two guys-400-425lbs, and average gear). I kinda thought it should be getting at least 40mph, or am I mistaken? Just wondering if the position of my motor could be off or what could be my problem(if any)? Before my speedo hole got plugged...it read right at 40...with a reading of about 42 being the fastest I had seen it, but my speedo hole is plugged now so I can't judge by it...but I know they are typically off anyways. Still got the stock aluminum prop(13x19).
Any of you guys know if what i'm getting is about right, or if does it seem kinda low to you guys? Just wondering if my motor might be positioned wrong, or what?
