I just picked up my new Lund 1875 ss last Monday. It has the Merc 115 ProXS and a 15 hp kicker. This is my second Lund in 8 months thanks to a drunk driver. I was worried about the 115 being underpowered for the 1875. Dealer assured me that it would have no problem. I had it on Table Rock Lake in Missouri for 3 days last week. The motor performed great! Got out of the hole fast and topped out at around 37 mph — which is plenty fast for me. Best part — that motor was extremely quiet when running full out. All three guys that rode in it commented on it.
