Hi ! i'm a new member on the Iboats forum. I have make a lot of Search on this forum before asking my question.
Peterborough Gemini 1988, open deck, 18,5 ft.
4.3 mercruiser Thunderbolt ignition 175hp
Alpha one ( dont know the ratio and my boat is store for winter )
Now, I have a Vortex aluminium 4 Blades prop, 18 pitch, 14.5 diameter.
ALone ; max speed 38mph, 4800-4900 rpm
With 6 people ; max speed really not fast, 4400 rpm.
. Which prop in aluminium I need to Buy to have the more speed ? I need aluminium for my Lake. Thank you !
My actual prop is perfect for Wakeboard and holeshot, but really not for crusing.
