Need help with boat set up

[ppgpro]

Thought you guys may be able to help me. I have a 1998 skeeter 185sx, I had a 150 yamaha but sold it and replaced it with a 200hp 2003 Merc with 19 hrs on it so it is like new. I am using a 10 " jack plate with a 25" trophy running 70 mph on GPS at 5900 rpm. Boat handles very good, no chime walk and turns very well. My problem is I just bought a 25" tempest because I was told it was faster, Well I am running the same speed but I am at 6300 rpm. Someone said I need to lower the moter on the jackplate because the tempest likes to run deeper in the water. Any input would be very helpfull. Thanks in advanced

Post this over in the "Props" forum. Mark or one of the guys should be able to help you. Welcome to BBC.

Typically 4 blade props are little slower then 3 blade. I think a 26p tempest may have been a better choice. Maybe that 25p has too much slip so dropping the engine 1/2" may help.

+1 on 26 tempest! I run a 26 on my 200merc on a sx 200. Runs 72, rpms are 6000+ right now with this cold weather, actually been lookin for a 27 tempest to turn during the spring. My advise would definately be to get or try a 26 tempest and by the way it does like to run deeper than the Trophy. I was runnin a 26 Trophy and gettin 67-69mph, Changed to the 26tempest and got 69 at the same setting on my 12in slidemaster. Scratched my head abit, fished a while, then dropped the plate only 1/2in, Hit my new high of 72! Gonna drop it another 1/2 in next time i take it out and keep doin it till i lose speed. I know its mindboggling tryn to setup a boat, but if you dont give up it gets better until u decide to get a bigger faster boat to mess with!

Thanks for the input, I am gonna go ahead and drop it a little and see if it helps. If not I guess I will try a 26"
