| i'm over-propped on my new rig...only getting 3000 rpms when starting out, which makes for a hard time getting out of the hole. also limited to 5100 rpms and 38mph top-end with the motor trimmed all the way up before it starts sucking air.
motor is a 90hp Optimax; came with a 13 3/4 x 21p Trophy Plus 4-blade prop.
the Merc prop selector tool suggests the following props:
for overall performance, mid-range, and handling:
- Trophy Plus 13 3/4 x 21p (current prop)
for acceleration:
- Trophy Plus 13 3/4 x 19p
- Vengeance 13 x 18p
for top speed:
- Trophy plus 13 3/4 x 19p
- Laser II 13 1/4 x 19p
i'd like to stay with a 4-blade for the lift getting on plane; does anyone have any suggestions for what i should try next?
or...could it be a motor height issue? mounted too low? it's in the 4th deepest hole, so it could be raised as much as 3 holes higher.
