precision gear drive

Post by bassinflats »

Just bolted on up to my 350 chevy motor and it seem like it takes more starter power to turn motor over. Do you have to go to a high torque starter. Motor seems to spin fast enough with old starter and no reduction box. Just wondering if I have a tired starter, even tried a different battery and same results. Only built one airboat before this and it was direct drive, any suggestions would be hlpful

I have a precision on my 406 ,it seemed to drag little bit more when the gears were newer and tighter but never did change original starter to a high torque.

i have a pretty basic 350 with a precision box. standard starter no trouble. make sure you got a good battery. if you have high compression you may need a gear reduction starter or just try a new starter

If its just a box and no prop it shouldn't make any noticable difference. It could be starter , bad ground, a number of things.
