I ran my 2000 20' Master Angler with a Merc 115 EFI 4 Stroke (390 lbs) paired with a Mercury Vengeance 16P prop since 2007. It had a fair hole shot but was sluggish when loaded. It ran well once on plane reaching a max speed of 38 mhp according to my GPS and sipped fuel. I just repowered last week to a mint Yamaha 200 HP OX66. After running the 115 4 stroke for five years, I can say that it performed ok. A 130 to 140 4 stroke Suzuki at 410 lbs seems to be almost ideal. Remember, transom weight is very important especially if you added a bracket. A 150 Yamaha 4 stroke is close to 490 lbs for 10 additional horse power. Ultimately, these hulls were designed to run mid power 2 strokes.
