Hey guys, new to the boat forum thing. Just this summer I bought a new to me Fish and ski boat. A 1992 Ebbtide Dyna Trak 181SS. It has a 1995 115hp Mercury out back. Long story short the boat is rated for a 150hp so I know it’s a bit underpowered. Anyway, I’ve been playing with it this summer and over all the performance is ok. Pulls a tube, hauls the family and cruises nicely but it has more to be desired. The boat has a manual 6” jack plate allowing me to adjust the height. It came with a 23p laser 2 prob but it was way to much for the motor and boat setup. I purchased a 19p spitfire X7 and it’s been an amazing upgrade. Planes fast, and runs close to rated RPM. All in with my current setup I’m able to achieve 44mph gps. Fastest seen was 46mph. Engine height is putting the prop shaft about 2-3” below the pad. 19p Spitfire prop as stated above running 4900-5100rpm. Loaded down it will still break 40mph but I really want to get close to 50mph with the 115hp. Is that achievable or am I dreaming? I know with a 150 it would be close to a 60mph boat which would be awesome but I’m trying to avoid a re rig for the time being. Any tips or advice that I’m missing that could increase my performance? I’ll attach a pic of the boat for you guys.
Thanks in advance!
