what size prop for a 20' sf

[jcraven]

I have a 1988 20' seacraft sf with a 150 merc and a quicksilver 48-16312-a5-15pitch (14" dia)prop. I am repowering to a 200 merc efi, any thoughts on what size prop to use. I'm concerned about over revving with the existing prop.

I installed a 2001 merc 200
Propgods recomended a quicksilver 151/2 x 17p seems to be good I seeing 5600 rpm wot

Quicksilver QS5011X Thunderbolt, equivalent is Merc Mirage+

ken at propgods said the quicksilver is the same as a mirage and recommended me saving some money perhaps vecause I was a forum member and found him on THT

I have a 2001 20' Master Angler (25" transom) that I just repowered with a like new 200 OX66. I am running a 19P Laser II turning 5400 rpms WOT at reliable 52 -53 mph on my Garmin - about 4% prop slip.

I have tried 5 different props and that's as dialed in as I have found for my rig.

Propgods is a great resource.

The Lazer is what No Bones has and it apparently works well - I have a 19" Stilletto, I would recommend a 17 though but I can't imagine a prop working any better across the board. In spite of my protests I don't think Ken handles Stilltto's yet. I don't think the Mirage+ with the large diameter works as well on a 20 as they do on 23's.
