1652 Weld-Craft. 550lbs dry, 73" beam. Total length with 21" transom pods is exactly 18'. '03 perfect running 50HP Johnrude mounted 3" above transom height. 10 Gal fuel tank in rear. 2 Group 31 AGM batteries up front. Trolling motor. Me 225Lbs, DW 120.
Boat tops out at 33MPH at 6200 RPM with 13" stainless 3 blade prop. That's 700 RPM over spec according to this info https://www.kirschbaum.at/ki_prop/pdf/2015/RPM Chart.pdf. Hole shot with pods is epic, literally up on plane and screaming over 5,500 RPM in a 3 count. Zero bow rise, it just shits and gets. Cruise is 25MPH at 4,750 RPM. Local prop pro at C&B Admiral says he can hammer out additional cup to reduce WOT 300-400 RPM for around $100 or put me on a new 15" stainless for $$$ that will drop WOT 400-500 RPM's. I would like to have a higher top speed at reduced RPM and higher cruise speed at 4,750 RPM.
We're old farts. We don't pull skiers, boat is primarily used to get us out to the party island 2.4 Mi. from my ramp at our weekend lakeplace.
