I have a 1980,115 Johnson Outboard on a Very Heavy 16ft Crestliner Fiberglass boat,I can get it up to 62kms per hour with 4 people in it .(I used a GPS to test this )
248lbs is the weight of 115 hp chrysler outboard motor
I saw one today with a 115 and some on line with more than that.
As long as you can secure the motor to something that will stand up to the engine's power, and you can get water into it so it won't melt, you can safely run an outboard off the boat. Unfortunately, the "securing the engine" part will hold you back - 115-horse engines will flip over any garbage can, oil drum, wading pool etc., you might come up with. Your best bet would be to take the outboard to a boat dealer and have it tank tested.
