GT10S is the real racing engine. GT10S is the model number of the 1967/68 Johnson GT-115 race motor.

When you get your camera ready for pictures, take some of the lower unit, especially the exhaust outlet and alternate exhaust outlet.

can you please give any more info

like speed, performance anything like that

[Bunny]

On your boat, probably 55mph ... its only 116.2 hp

Your speed will be zero until you find one of the special props made for this motor. As you were told earlier, props for that motor are very rare.

i have two props
both brass both are twin blade but with different pitches

[beefurmm]

it does take a long time for information

still looking for as much tech spec on this engine

[Bunny]

Exactly what are you looking for? Scrutineer's sheets?


Performance and speed depend on the boat, not the motor.

I am sorry I do not have any information on your boat. On completely different boats the motor is capable of approximately 80 mph, but not on a boat such as yours.
