Prop for Seafari w/4.3 Mercruiser

[rhody98]

Been looking at the posts here on props, lots of plugs for the Mirage plus on the Seafari....and lots of good info for prop size for a 150 to 175 hp on a 20'. With the 190hp sterndrive, the merc prop selector says 14.5 x 19 for all around performance. Can't say I would be as interested in top end....but one never knows when the wild hair will appear. In any case I have seen 15+ x 19 3-blade mirage and mirage plus props on ebay. Thoughts on this size?

When I bought the boat last Fall there was heavy enough chain in the forward storage to drag a dozer out of the swamp, didn't think much about it that time and didn't ask the previous owner but pondering now he must have been trying to keep the bow down. I haven't had the boat in the water and it didn't come with a prop so I'm starting from scratch.
