Henry & Lynn, which prop do you have on the Yahama? If you have the 11-3/4in pitch prop, that is a speed prop. It will bog down trying to push a heavy boat with a displacement hull. The 9-1/4in power prop would allow the engine to spin up higher rpm, where the power is. Cost would be $100. You should be able to hit hull speed with ease. Fuel consumption would go down, as you could make 5kts at half throttle. Just a thought. Don, #6293, Niceville, FL

We had it removed, as it was pushing the aft end 6" down into the water. We have a 1992 Yamaha 9.9 hp 4-stroke on a bracket, with a 6-gallon plastic auxiliary fuel tank (plus an additional 5-gallon lawnmower-type fuel tank). We can go 4.5 knots all day long while using 1/2 gallon per hour - we can exceed 5 knots with the engine opened up all the way. We'll never reach hull speed with this motor, but it's quiet, fuel- efficient and reliable. To keep our batteries charged, we leave small solar trickle-chargers out in the cockpit while we're away and use either a generator or shore power to operate our battery charger. We also now have a nice storage area (where the A4 went). We stow the generator and a 135 amp-hour deep cycle battery down there - the battery runs all sorts of things, from my wife's laptop to fans to my CPAP machine (I have sleep apnea). All in all, a 9.9 4-stroke is a perfectly adequate powerplant for a C27. And, the new ones will put juice back into the batteries while they're running, according to a salesman at the Baltimore boat show. Fair Winds to you & enjoy your C27.
