what prop shoud i use

miklem Posted 8/27/2011 4:06 PM (#100415) Subject: what prop shoud i use Member Posts: 17 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?

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. miklem Posted 9/2/2011 5:15 PM (#100497 - in reply to #100415) Subject: Re: what prop shoud i use Member Posts: 17 I'll give it a try,thank you
