Hello, I have a question regarding whether I can use a series 30 t.c. For a 301 predator with stage 1 improvements. Or should I use a series 40? Going on a manco 606. I know the 30’s are 3_7 hp and 40’s are 8-14 hp have a yerf with a 30 on it but the manco is heavier and two seater. Any advice would be appreciated!
