Yamaha 75hp / 80hp / 85hp upgrade kit

All genuine Yamaha parts for Yamaha 75hp - 85hp two stroke to upgrade it to full 90hp.

- high compression cylinder head
- free flowing exhaust
- set of carb jets

75hp and 85hp have low compression heads and require the high compression head.

75hp and 80hp have restricted exhausts and require the free flowing exhaust
All in good condition, 100.

I'm running a custom machined head and my own exhaust system on my own ported 3cyl engine with surface piercing prop so these are of no use to me! - I have stripped four of these engines down recently for their cranks and blocks if anyone needs any other parts.
