Coupler Help

[z400]

Hey hey


im unsure of what coupler i need for my nitro engine.

Im running a GoTech .25 marine engine in a 32" shallow vee

well i need a coupler to adapt the engine to the flext shaft
was just wondering if the 5mm nitro coupler that OSE has will work
on the big block engines?
im running .130 flex cable by the way also.



Thanks!

I would think it would be a threaded coupler...check OCtura out. They should have something.

yeah, it is a threaded coupler i know that


but i dont know what size i need.


It doesnt matter now really, im switching flex cable sizes so i can use the coupler i have now

Sounds like the smart move anyway...unless it is a smaller than it can take. You should be able to find a manual online or your book that shows the motor thread size. Probably metric.
