Ideal Prop for 21' Pontoon

[Citron]

Hi all.

I have a 09 Premier Sunsation LTD 210 with a Honda BR75 on the back. The toon has 25" tubes and an Aluminium 14X11 Solas prop (MD4908). If I am by myself with a full tank I'll hit about 6100 rpms and if I have 4-6 adults onboard she'll still hit about 5900-6000 rpms. Based on Honda specs it has max hp at 5500 rpms and operating range from 5-6k. I am looking to pick up a new prop and wouldn't mind dropping the rmps a little to. Should I try to target the max hp at 5500 rpms? I am also going back-n-forth between a 3 and 4 blade prop.

Any suggestions would be greatly appreciated.

Thanks

Every degree of pitch will raise or lower the rpm by 200.. You might try a 13.. That might hit right in you area and you should gain just a tade bit of speed..
