I was thinking a e-tec 130...would putting a 150 on the back be to heavy? Does anyone have a 20' with a e-tec 130 on the back to give me some performance #s? I have two batteries underneath the very front of my console and a brand new stainless below deck tank under console too. Any info or advice is appreciated!

EV, I believe Skip & Carla's 19 Bowrider (which is a couple hundred lbs lighter than your CC) with a 115 E-Tec will run about 37 mph with an aluminum prop. I think fuel consumption on it would be similar to your f115. My experience is that with a good stainless prop, you can raise the motor 1 hole and pick up as much as 3 mph. The 130 should easily put you into the low 40's. The 150 is almost overkill for a 20 IMHO, unless you carry very heavy loads or like to cruise at 30-35 mph! It's a much heavier and more powerful motor that will burn more gas, but give you speeds in the very high 40's and let you cruise at 30 mph with less noise than your f115! Denny
