1998 Merc 200 Efi Prop Help
I was looking for some input on a prop and rpm for this motor. Right now it is on a 21 foot fish and ski boat with a 26P 4 blade prop and I get about 5200 rpm @WOT and in about 57 MPH on the GPS with only me and baout 1/2 fuel. This does not seem right to me. Is it? Let me know your thoughts.

go down in pitch. probably a 24p of the same style prop should get you close with a good holeshot as well

if you going to be skiing you may want a 22. hy HS voyager use a 23 for speed and ski. it turn up to 6300 depending on the JP heigth. you need to keepit under the RPM for the oil injection and pastic bearing carriers. you shold be using a 4 or 5 blade prop se well.
