I have been puting this off for a long time,but finaly have to make a decision.

I realy need help on this one.

When I bought the Yanmar 6LP-STE's (300 hp) I was sent 19X18X No.3 cup, three bladed props.

Gear boxes are Hurth 630 A 1 1.6 which are really 1.56 and 1.58.

A while back Tommy Drake was kind enough to send me some data but I think there is more info available now.

I think these props are not right,I could be wrong,not the first time.

I have to hand carry them to Miami,exchange them and carry them back,with a stop in N.Y.

Please help select the proper size!!!!

P.S.The boat is heavy.

Greatfuly,

Bill Moyka
