The engine is a yamaha 9.9 4 stroke. would it be powerful enough to troll with a 3-5 mph. also would it be powerful enough to limp home with in case the main engine fails on a 23 foot conquest thanks

I would expect that it would be enough to troll in that range, 3-5mph, but not any faster.

Yamaha has a high thrust 9.9. It puts out (from what I hear equal thrust to a 35 hp) I think that it is only the prop and possible the gearing. You could then get 5 to 6 mph.

You'll be limited by the thoeretical displacement speed of that hull, not the horsepower. A 5 or 6 horse would get you up to that same speed, but require full throttle to do it. The 9.5 will get you there at less than full throttle and live longer in the process. On the Conquest 23, that limiting speed is around 5.5 mph. Whether it is 6, 9, or 20hp, that's as fast as you'll go until you get enough HP to climb your bow wave and plane. That would take 100plus ponies to do.BillS
