Please help - I recently bought a new prop for my Johnson 70 (2 stroke)?

Question

The old one has the indent where the was fits behind the nut, the new one has no indent for the prop, the dealer said its a new type but i dont think so, I paid £180 (sterling) for it, the centre piece seems to be wrong way round as indent for washer is at back, i think the sized is 11.5 by 14 or something

Answer 1

take you boat to the dealer and tell them to prove it if they said it is a new type then it may only fit the new type of motor

Answer 2

just so you know... there is no "new prop" for the 70 2-stroke. that motor has not been made since 2001 -2002 ish. so, i would return that prop ( because it is not the right one ) and ask for a refund. then i would leave that shop and never go back. they obviously do not know what they are doing and with engines costing what they do these days, you can't risk ruining your motor.

your 70hp power is the 3 cylinder engine with the large gearcase correct? the correct size and pitch is determined by the size boat you are running... here is the break down

16-18' 13 3/4 dia. 15 pitch

15-17' 13 1/4 dia. 17 pitch

14-16' 13 dia. 19 pitch

13-15' 13 3/4 dia. 21 pitch
