Will a 40 hp motor pull a tuber on my 14 foot boat?

Theres a boat for sale that is 14 foot MFG Niagara with a 1960 Johnson Super Seahorse 40hp motor. He says it will pull the donkey out of a tuber. Anyone know if this 40 will get the job done?|||Yes easy...I used to pull skis, boards, tubers, other boats, and lots of things with a 25 hp Johnson Seahorse on a 14 ft molded mahogany boat back in the 1950's...





I am sure your 40 hp engine will do a better job|||Yes it will my exboyfriend had a john boat with a 40hp motor and we tubed all summer it was a blast just dont get the rope caught up in the motor!|||maybe with a beach start it will pull one kid... get a test drive from the seller, beats getting something that will not do what you want... offer to buy the gas !|||Think about it, that motor is old. Back when it was new, it had more power. That 40 hp is equal to to days 25hp. You can always change the prop to a lower pitch and get more pulling power. Just make sure the rpm does not go beyond 5000. The motor being in good shape could pull a tube, even a skier on 2 skies with some experience. But it will be no speed demon. Maybe 17-25mph.|||Not familiar with that boat but if it is not overly heavy, yes it will work fine. Gotta remember for safety you need two ppl in the boat. Never took a donkey tubing, what type of life jacket does he use? Just curious.|||Yes,





Something to consider though,


how much weight will determine the amount of pitch on the prop.





Probably would be best to start somewhere in the 15 pitch and work your way down to possibly to a 12 pitch.





Hope this helps|||if you are at a low elevation and have little weight in the boat and the tuber is small, then yes. I had a 1960 Glasscraft with a 35 hp Johnson and it could not pull most adults at 5000 elevation|||Yep|||why not?|||Depends on your altitude. A motor looses 3% of its horsepower for every 1000 feet above sea level. I live at 7.000 ft so your 40 HP would be a 31.6 HP here. If the boat is one of those old heavy fiberglass scows I sure wouldn't put much faith in it. Years ago I had a 14' starcraft with an Evinrude 40 HP at about sea level. Top speed was about 24 mph, we could pull a single skiier. But those tubes really need to get up to speed to skim on the water, go too slow and all they do is plow through the water.


Best idea is to go take it for a spin and see how it does.
