    15 RT188 115 Pro XS 2 Stroke

    I’m debating making the move to SS. Looking at max rpm it appears 5000 to 5750. Loaded 15 RT188 115 Pro XS 2 stroke, 12-75x21P Black Diamond I was able to achieve 44.7 mph gps @ 5300 (Vessel View) on fairly calm water in 55/60 degree ambient temp. No water pressure available, no JP, 2 hole down.
    I’m in the middle of that “tolerance” I guess you call it. Is there a sweet spot in that zone to shoot for without jeopardizing reliability. Seems the Laser 20 is a popular option for this hull. Go with a 20 or 19? .
    I copied this over from the motors section so disregard the highlighting.

    That’s 2 votes for the 19P. I’ll start looking for a vendor to purchase.

    Anyone aside from Rothwell offer an exchange program? Rothwell has none in stock, and does not qualify for the program if I special order now. If I order with “their” bulk prop order in a few weeks it does since it would not be considered special order.
