| I have a 2005 620 w/225 merc opti w/ a Rev 4 19p 4-blade but its a slug out of the hole and 54mph on top @ 5500-5600rpm. What prop would be best? |

Also have you tried anything with PVS system on the prop, you could possibly open them up and see if that helps holeshot.

| 21 or 23 tempest is probably the best all around prop for that combo.
If 1 19 doesn't get that thing up, then it must have all the holes plugged. Try opening them up. 1/4" 3/8" and finally remove them, and see the changes.
Rev4 is a big diameter prop, and that's a lot of bite to get turning. The motor needs the prop to slip a bit on the hole shot. |
