Four stroke v Two Stroke

Sal marine have just put three Suzuki,s 250 F/Stroke on a 10.5 ring rib.
I said wouldn,t three 250 E-tec,s be the choice as they are supposed to do every thing a four stroke dose and have a big weight advantage.
The man said they wont fit two strokes due to there lack of TORQUE
What did he mean ?

I don't know about the specifics of the e-tec vs. the Suzi's. However torque => acceleration, while HP => top speed.

My guess would be that torque limitations on a boat are more due to propeller selection and slippage than any limitations of an engine's output. Undoubtedly someone who knows more about it than me will correct me and provide more detail!
