TOPIC: 1961 lark 40 hp

I am new to the group and have some questions... I have a 1966 starcraft 15 foot boat and just bought a 1961 lark 40 that seems to run well and seems to "spit" plenty of water. I am sure that it's ready to run the question is... what is the difference between a lark III and a ski twin? I am hoping to pull the kids on skis and a tube I'm hoping the lark will do the job... any input and or information is appreciated


Thanks
Marty

The 40hp should be enugh to pull a skier or tube what the small of a boat. The diffrent between the motors I'm not suer and they the same hp?. If theyu are the same hp then both should perform about the same.
