right gear ratio

[qaztwo]

I have two old mercruiser manuals, and the stern drive one states for my engine a 351, I need a gear ratio of 1.33 to 1. I bought one recently that was 1.5 to 1, couldn't find 1.33, thinking that I could use a larger pitch to help gear down the drive. Will this work, and most importantly will it not put to much strain on the engine and drive.

Yes.<br /><br />

If the correct rpm at WOT are achieved then no problem.<br /><br />C............

Re: right gear ratio

in many cases at high altitudes drives are regeared to a steeper gear ratio to lighten the load on the motor.

That 1.33/1 ratio gear set is about as common as Hen's Teeth...........<br /><br />The 1.50/1 will work Just Fine............

Re: right gear ratio

I didn't even know they production made 1.33/1 drives. Is this a 351 Winsor or Cleveland? If “W” I had one built up pretty good (hi H.P.) a couple years back and a 1.5/1 drive worked fine.

Re: right gear ratio

Thanks for the replies, and it is a winsor. I found one drive that had the 1.33 ratio, but it looked so bad that even if the gears where still good didn't know if I would use them.
