Hi All, I am thankful at times like this for forums.
got a fibergl*** 3 hull deck boat (older sunbird) and just put a 150 yr 2000 evinrude outboard on. tried a few props available from friends: Stainless OMC, Viper. Viper 14-3/4-17 is giving me ok performance...i bought a Solas rubex 14-1/4x17 and i lost 8mph and had lots of cavitation...(prop had no cupping) and lost trimming.
Unfortunately i am overseas and can't go to a dealer or store to see the physics of the different propellers.
My engine is slightly higher than normal, and need to have trim to get speed up. i use the boat in the ocean.
i am researching again and don't know out of all the following props is best:
i have read up on these props but their are no figures to describe the amount of cupping and raking etc.
Also because i am overseas, i prefer a replacable hub.
Viper : Rebel: SSTII: Hydrus:Renegade B***: Cyclone.
The Hydus says agressive cupping, but don't know if its better that Viper?, SSTII mentions double cupping...is it better than Viper?, i have read there Rebel has better fuel economy and performance than viper, does this mean it will be better for me? help please. I would also like to move to a pitch 16 as i only get 4700 rpm at WOT.
