On a side note – I picked up an ’88 70hp that at a casual glance appears to be a frankenmotor. The carbs look like they are off a 78 motor, and gearbox possible a 70’s gearbox too.
So this year I’m venturing into the 70hp motors. What should I know about respecting what can go where in terms of swapping parts, and what can’t?
I would say this frankenmotor is wrong as it sits, because the late production ’93 70hp I have sitting on my personal boat has adjustable low speed needles and some other stuff that creates idle headaches during initial calibration. I’m pretty sure that engineering ideas for fuel system components didn’t regress for OMC in the late 80’s 🙂
