One thing I don't see discussed much is the noise. My daughter is a competitive sailer and we use the boat to coach/watch events. Spend time around four-strokes and you yearn for the quiet when operating at slower speed.

The E-Tec noise levels are about the same as the 4-strokes but the sound quality is a little throatier at idle; mine is actually a couple of db QUIETER than a 4 stroke at 30-35 mph!

First post here also - A friend of mine found me a very great condition 1981 23' Seacraft close to home. Not doing a full restore yet due to funds but I am changing fuel tank, floor panels, patching some spots and repainting, etc, it had twin 150hp that did not come with the boat and I am looking to repower. Not planning on a bracket yet either. I measured from bottom of V to stock transom cap and it is about 28 1/2 to 29 inches. But the boat will not be sitting in the water at that angle right? I have the option to buy 2 99' yam 250s in great condition at a bargain price from a re-power but they only have a 25 inch shafts. Will I need a 30" shaft for a big single as opposed to twin 25 inch shafts? Or can I get away with a 25 inch single shaft length and try to find a prop that will work. Thought I would ask the experts since Seacraft Corp. and my local marine dealer are unsure?

You have a 30" transom. If you go with a single you will need a 30 inch shaft on the motor. If you go with twins you will need 25" shaft motors.

Question ? where is the measurement taken from in determining the shaft length.I have a Suzuki 225 2 stroke mounted on an Armstrong bracket. I have wondered about the shaft length/mounting height of the motor , I have a hard time keeping the boat on plane at less than 22 MPH in rougher seas , no problem in a calm sea. Thanks in advance

Thanks Rich! Anyone know the approx. cost of buying a bracket and putting it on and enclosing the transom, not including the hours of work.

Min planing speed is a function of weight, CG location and how much stern lift you're getting out of the prop. Trim tabs will also help a lot, but you might consider trying a 4 blade stern lifting prop. The PowerTech prop guys told me that having more blades improves stern lift, so just about any 4 blade prop is better than a 3 blade for same blade configuration.
