Mako 25 props

[mdman352]

I recently bought a Mako 25 with 175 Evinrude 2 strokes. Any ideas on the prop size that should be on a boat this size with these motors???

Thanks for any advice.

What year 25?

What props are on there now and what performance numbers are you seeing.

are the motors on the transom or a bracket?

1979 Boat with motors on the transom. Today with a light load in 1'-2' tight chop, 3800 rpms was 25-31 kts depending on how I trimmed the motors. The boat/motors really like 4000 but that is faster than I wanted. They did rev to 55-5600 rpm WOT. Speed was 42 or so trimmed all the way in. If I trim the motors up I could go another 3-4 kts.

The Props (Viper) seem to be ok.

That sounds about right if you have bottom paint and wet foam. Do you have a tower or a t-top? What year motors?

[mdman352]

'96 motors. No tower, just a top covered with material/canvas.

Not sure about the foam but I have pulled out handfuls of foam that had been 'removed' from somewhere...I pulled it out of the transom area. Must have been done during tank/transom work. No bottom paint. Props are no where near "perfect" and I will have them tuned this winter.

I would love to find a fiberglass person in the mid Atlantic area so I could get some numbers on redoing the inside and outside finishes with some change in the layout.
